Abstract
A panel for roofing or siding applications, with a nailing flange along its rear edge and decorative elements simulating natural materials along its front edge. The panel has a longitudinal locking mechanism that allows the panel to be interlocked with similar panels in front of and/or behind it in a water-resistant latching manner that prevents both front-to-back and upward movement of the interlocked panel, while simultaneously encompassing and protecting the nailing flange. The panel includes a transverse locking mechanism for interlocking the panel with similar panels on either side of it in a water-resistant manner. The panel is preferably made of a blend of rubber tire drums and plastic. The panel has a support structure that offers support against pressure applied to the top of the panel while simultaneously providing an integrated venting system for the system of interlocked panels. Starter strips and accessory caps with similar features facilitate the installation of the system of panels onto a substrate.
Description
ROOFING PANEL SYSTEM
Technical Field The invention relates to the field of roofing and siding, and more particularly to a system of interlocking panels that can be used for roofing and/or siding applications.
Back round Roofing and siding panels of various kinds are known. Such panels are generally fabricated with raised decorative elements simulat-ing classic roofing and siding materials such as, for example, shake, tile, brick, stone, and slate. Such panels may be fabricated from they-moplastic sheets, by injection molded plastics, fiberglass molding, and metal, among other materials . In comparison to real wood shakes or tiles, such panels are generally easier t~ install, require less care, provide a reduced fire ha~ard% and provide greater durability.
Summary of Invention A roofing system according to the present invention includes high-profile panels made from recycled rubber tire crumb and recycled industrial polymers such as polyethylene and polypropylene or other virgin plastics.
The panels incorporate a longitudinal locking mechanism along the length of their front and back edges that allows each panel to lock to its neighbor to produce a weather-resistant closure. This longitudinal locking mechanism allows the panels to be continuously staggered to avoid any repetition of pattern that would be unappealing to the eye of the beholder. The portion of the longitudinal locking mechanism along the rear edge of a panel protrudes upward, while the portion of the longitudinal locking mechanism along the front edge is a longitudinal cavity within an indented region on the underside of the panel, into which the rear edge of an adjacent panel can latch. This longitudinal locking mechanism allows the panels to expand and contract and tighten with exterior forces, such as wind.
Fasteners, for example nails or screws, may be used to fasten each panel to a substrate along its rear edge through a nailing flange in marked preferred locations. All such fasteners are protected by the longitudinal locking mechanism against exposure to the elements.
The panels also have transverse locking mechanisms on each side, adapted so that adjacent panels can be locked together in a side-to-side manner. This transverse locking mechanism may be a hook and lap arrangement, which offers a tight lock and easy alignment of the panels during installation.
When interlocked together, the panels offer protection against wind, rain, and other elements of nature. wilt-in cavities along the front edge of the panels and in front of the longitudinal locking mecha-nism diffuse wind-driven rain pressures and resist the entry of rain along the front edge of the panel. If rain were to get past these cavities, it would be quickly diffused when it reached the longitudinal locking mechanism and would drain naturally away.
Additionally, the panels have supports built into the under surface that evenly distribute forces to the substrate when the panels are walked upon.
The undersurface is also specially designed with an integrated venting system that allows for continual air flow under the panel, reducing the possibility for moisture build-up from underneath, which is a common source of wood rot or mold.
The panels can be manufactured to look like wood cedar shakes, concrete tile, Spanish tile, Italian tile, slate and other textures on their top and/or front visible surfaces. Many other designs may be imparted to the visible surfaces as may be required or desired. The panels can be colored to numerous synthetic colors to emulate the colors of nature -for example, greys, black, or browns.

The panels ° polymer and rubber matrix makes them flexible and gives them a high coefficient of expansion and contraction. Being composed of recycled materials, the panels may be an environmentally friendly and cost-competitive alternative to natural products. Addition-s ally, the panels are themselves recyclable; if ever a panel has to be recycled, it can simply be re-ground and reprocessed. The durability and resistance to ultra-violet radiation of the polymer matrix offer an extended life expectancy of about 50 years.
The panel design allows for easy application, thus cutting labor costs and installation times. Because each panel contains an assembly of three to five pieces of textured decorative elements (for example, simulated shakes or tiles), they are easy to handle and install. For example, the panels can be made about 16 inches by 40 inches (40 cm.
by 100 cm.), with an exposed surface when installed of about three square feet (300 square cm.) and a thickness of about 1.g in ches (4.5 cm.) at the thickest protrusion.
while the most common usage of the panels is for roof applica-dons, they may be also used for other applications - for example as siding.
Accessory caps may be used on roof applications in respect of changes of direction on various types of roofs - for example, on gables, ridges, hips, or valleys, otherwise to cover any change in direction where there are exposed edges of panels. These accessory caps incorporate similar design features as the panels.

Description 'Throughout the following description specific details are set forth in order to provide a more thorough understanding of the invention.
T-lowever, the irwention may be practised without these particulars. In other instances, well known elements have not been shown or described in detail to avoid unnecessarily obscuring the present invention. Ac-cordingly, the specification and drawings are to be regarded in an illustrative, rather than a restrictive, sense.
Figure 1 is a top plan view and Figure 2 is a front elevation view of a panel 10 according to an embodiment of the invention. Each panel 10 is preferably manufactured from a blend of recycled rubber tire crumb and recycled industrial polymers such as polyethylene and polypropylene or other virgin plastics. Such a polymer and rubber matrix makes the panel 10 flexible and gives it a high coefficient of expansion and contraction; expansion and contraction will be minimal but the flexibility of the panel 10 makes it resistant to cracking or breaking. The preferred material composition also makes the panel 10 essentially impervious to water absorption or penetration. Being com-posed of recycled materials, a panel 10 with such a material composition may be an environmentally friendly and cost-competitive alternative to natural products. Additionally, such a material composition would make the panel 10 itself recyclable. If ever a panel 10 needed to be recycled, it can be simply re-ground and reprocessed. The durability and resistance to ultra-violet radiation of a panel 10 with such a material composition offer an extended life expectancy of about 50 years. A
panel 10 of such a material composition also has high insulation and sound dampening qualities. It is also lightweight, reducing the stress and structural pressures on any building on which the panel 10 is in-stalled.
Even so, a panel 10 according to the present invention could conceivably be manufactured from any type of material or blend of materials, including rubber, plastic, fiberglass, metal, and/or other natural or synthetic materials.
Although the most common usage of the panel i1is for roofing applications, it may also be used for other applications, such as siding.
Referring to Figures 1 and 2, a panel 10 according to an embodi-meat of the invention includes decorative elements 12, the top and frontal visible surfaces of which may be characterized by simulated textures of wood shakes (cedar or otherwise), slate, stone, brick, concrete tile, Spanish tile, Italian tile, other tile patterns, or any other effects. Many other designs may be imparted to the visible surfaces as may be required. The panel 10 may be colored to numerous synthetic colors to emulate natural colors - for example, greys, black, or browns .
Although each panel 10 is a unitary member, the decorative elements 12 are preferably separated by gaps 14 to give the appearance _7_ of discrete shakes, tiles, or other natural materials affixed adjacently.
The decorative elements 12 are preferably staggered so that their frontal faces 16 form an irregular pattern when viewed from the top. This irregular pattern avoids the artificial appearance that the frontal faces 16 would present if they were perfectly aligned. As noted, the frontal faces 16 may also have simulated textures imparted to them to provide integrity and consistency with corresponding simulated textures im-parted to the top surfaces 18 of the decorative elements 12.
Although each panel 10 could conceivably include just one decorative element 12, the panel 10 preferably includes a plurality of decorative elements 12. For example, each panel 10 can have a single row of three to five decorative elements 12 in the form of simulated 511akeS or tiles. A typical panel 10 with a single row of about three to five simulated shakes or tiles can be, for example, made about 16 in ches by 40 inches (40 cm. by 100 cn~.), with an exposed surface when installed of about three square feet (300 square cm.) and a thickness of about 1.g inches (4.5 cm.) at the thicl~est protrusion. A panel 10 of this approximate size, combined with the general lightweight nature of such panels 10, make the panels 10 easy to carry, position, align, and install, thereby cutting labor costs and installation times. It is possible for each panel 10 to have a plurality of rows of decorative elements 12 rather than just a single row. I~owever, if the overall size of the panel 1is to be maintained at about 16 inches by 40 inches (40 cm. by 100 cm.), each decorative element 12 would then need to be made smaller, which might be desirable for some applications but the decorative elements 12 might then no longer simulate the sizes and proportions of actual shakes and tiles commonly found in building applications. Alternatively, the size of the panel 10 can be made larger, but this should be balanced against having a panel 10 sized for optimal ease of carrying and installa-tion.
_g_ Referring to Figure 1, each panel 10 has a nailing flange 20 along its rear edge. The nailing flange 20 has recessed indicators 22 to show preferred locations where fasteners may be inserted to affix each panel to an underlying substrate. Fasteners, for example nails or screws, 5 may be used to fasten a panel 10 to a substrate or structure at one or more of each recessed indicator 22.
Figure 3 is a bottom plan view of a panel 10 according to an embodiment of the invention. As shown in Figure 3, a panel 10 accord-ing to this embodiment is not of solid construction, but is preferably 10 hollow other than a network of structural supports that run between the outer edges of the panel 10. In particular, a network of longitudinal supports 24 which run from one side of the panel 10 to the other side, and transverse supports 26 which run from the front of the panel 10 to the back, form an overall structure that allows for contact and support of the panel 1~ to the substrate to which it is fastened w1t11out the need for the panel 1to be completely solid. The structure formed by the longitudinal supports 24 and the transverse supports 2~ distributes any weight or forces of pressure that may be imparted to the top surface of any panels ~ 0 and evenly dissipates those pressures to the substrate, whether such pressures are caused by elemental forces such as wield or by someone walking on the panel 10, all without causing damage to the integrity of the panel for the substrate. The longitudinal supports 2 and transverse supports 2provide strength and integrity to each panel 1, but allow the panel 10 to be manufactured using less material, while achieving a more lightweight panel 10 that is both easier to install and easier for the substrate or underlying structure to support. The struc-tural supports need not be in a grid pattern as shown in Figure 3; any other pattern that similarly distributes weight and pressure will also be effective, although a grid pattern allows for simpler and more cost-effective manufacturing.
Referring to Figures 3, 5, and g, structural cavities 25 created by the multiple intersections of longitudinal supports 24 and transverse supports 26 also enhance the isolative qualities of the panel 10 by encapsulating pockets of air which become part of the natural insulation mechanism of the panel 10. Along with the thermal qualities of the composition of the preferred materials used in the manufacture of the panels 10 themselves, the air pockets within the plurality of structural cavities 25 give the panels 10 further isolative qualities which assist in cost savings in the heating and air conditioning of buildings on which panels 10 are interconnected into roofing or siding systems in hot or cold climatic areas.
As best shown in Figures 5 and ~, the longitudinal supports 24 and transverse supports 26 are preferably slightly recessed from the bottom of the panel X10 relative to the outer edges of the panel 10 - in 1~ particular, the side edges; this permits movement of the air pockets trapped under the panel 10. Accordingly, the slightly recessed longitu-dinal supports 24 and slightly recessed transverse supports 2~ together form a structure which both provides structural support to the panel 1 and assists in the dissipation of any built-up moisture underneath the panel 10 that may be created by moisture vapor which may percolate from the substrate or otherwise, thereby resisting damage caused by moisture in the form of damp rot, fungus or mold which proliferate in areas of dampness. In other words, the longitudinal supports 2and transverse supports 2provide both an effective support structure as well as an integrated venting system for the panels 10.
In addition, as shown in Figures 2, 3, and 5, a plurality of slots 27 in the bottom surface of each panel 10 near its front and rear edges connect air pockets that may otherwise be trapped beneath each panel 10 to pass to adjacent panels 10 to which they are connected, thereby creating a complete and integrated insulating air blanket under a system of interconnected panels 10 to further alleviate the chance of any mois-ture or vapor build up under a system of interconnected panels 10.
Such systems of interconnected panels 10 are shown in Figures 4 to 7. As shown in Figures 4 to 7, a plurality of panels 10 can be con-s nected together to form an interconnected system of panels, intercon-nected both in a side-to-side manner and in a front-to-back manner.
With respect to the front-to-back connectivity, each panel 10 has an element of a longitudinal locking mechanism along its length near each of its front and rear edges that allows it to interlock with an adjacent panel 10 in front of it or behind it. With respect to the side-to-side connectivity, each panel 10 preferably also has a transverse locking mechanism on its sides that allows it to interlock with an adjacent panel 10 to its side. both the longitudinal locking mechanism and the trans-verse locking mechanism will be described in more detail below.
Deferring to the cross-sectional side views of tl~ae panel 10 in Figures ~, 9, 11, and 12, a longitudinal protrusion 28 extends upwardly from the panel 10 in front of the nailing flange 2~, and forwardly toward the frontal faces 1. Referring to Figure 1, the longitudinal protrusion 28 preferably runs the length of the panel 10 near the rear edge of the panel 10 but in front of the nailing flange 20. Tllis longit~-dinal protrusion 28 forms one half of a longitudinal locking mechanism that permits a panel 10 to be longitudinally interlocked with an adjacent panel 1. In particular, the longitudinal protrusion 28 of one panel 1 interfits and interlocks with a corresponding longitudinal cavity 30 near the frontal faces 16 of an adjacent panel 1, as shown in Figures 11 and 12.
Referring to Figures 10 to 12, the underside of each panel 10 has an indented region 32 proximate to the frontal faces 16 of the panel 10.
The indented region 32 of each panel 10 is adapted to receive and encompass both the longitudinal protrusion 28 and the nailing flange 20 of the adjacent panel 10 in front of it. Each indented region 32 has within it a longitudinal cavity 30 which interfits with and interlocks, in a latching manner, with the longitudinal protrusion 28 of the adjacent panel 10 in front of it. During installation, after the frontmost of two adjacent panels 10 is fastened through its nailing flange 20 to the under-lying substrate, the indented region 32 of the rearmost of the two panels can be placed over both the longitudinal protrusion 28 and nailing flange 20 of the frontmost panel 10 and then pulled backwards until its longitudinal cavity 30 has interfitted and interlocked with the longitudi-nal protrusion 28 of the adjacent panel 10 in front of it. ~nce the 10 longitudinal cavity 30 of the rearmost panel 10 is interlocked in a latching manner with the longitudinal protrusion 28 of the adjacent panel 10 in front of it, the resulting longitudinal locking mechansm prevents the two interlocked panels 10 from moving perpendicularly away from each other. 'I'he indented region ~2 also, when the panel il0 is viewed from the side, encompasses and protects the nailing flange 20 of the panel tin front of it against elements such as water, wind, or wind-driven rain. Further, once the rearmost of the two panels 10 has also been fastened to the underlying substrate along its nailing flange 1, the 1~ngitudinal loclging mechanism prevents both bacl~ward movement of the panel 10 as well as upward movement that might otherwise be caused by wind uplift and rain near its frontal faces 16, without the need for additional fasteners near the front of the panel 1.
Deferring to Figures 3, 5, 7, ~, 10, and 12, further resistance to elemental forces is preferably provided by a plurality of additional cavities 3along the underside of the panel 1, running strategically along the full length of the frontal faces 16 of the panel 10. Each such cavity 34 creates a vacuum break which disrupts any wind-driven rain or water that may pass along the underside of the panel 10, thereby resisting the hazardous effect such elements could potentially cause, and draining the water naturally away.
Referring to Figure 12, any wind-driven rain or water that some-how penetrates under the panel 10 past the cavities 34 is then stopped by the longitudinal locking mechanism formed by the longitudinal cavity 30 of the panel 10 interfitting and interlocking with the longitudinal protru-sion 28 of the adjacent panel 10 in front of it, which together create a water-resistant joint which provides further resistance from wind-driven rain or other elements which might otherwise penetrate under the panel 10. This longitudinal locking mechanism also protects the nailing flange 20 of the front panel 10 and the fasteners used to secure that panel 10 through nailing flange 20 to the underlying substrate. For even further protection, as shown in Figures 8, 11 and 12, each panel 10 can have a water stop 36 along the full length of its rear edge behind its nailing flange 20, to further prevent moisture from penetrating past the water st~p 3to reach the underlying substrate. ~s shown in Figures 11 and 1 ~ 12, the longitudinal protrusion 28 of one panel interfits and interlocks with the longitudinal cavity 30 of an adjacent panel in a manner that adds strength to the system of interconnected panels 10 and that in-creases in strength with any exterior force that causes lift, such as wind.
As shown in Figures 4 to 7, the configuration of the longitudinal locl~ing mechanism, namely, a substantially continuous longitudinal protrusion 28 to which a corresponding longitudinal cavity 30 of one or more adjacent panels 10 can be latched at an indefinite number of points along the length of the longitudinal protrusion 28, allows for a continu-ous side-to-side adjustment of adjacent rows of interlocking panels 10 to achieve a laterally staggered effect, and prevent the proliferation of any ongoing noticeable repetitive design which may have a negative appeal to the look of the visual elements of the panels 10 when used in a system of such panels 10.
In addition to a longitudinal locking mechanism for allowing a plurality of panels 10 to be interlocked together in a front-to-back manner, a transverse locking mechanism is also desirable for allowing panels 10 to be interlocked together in a side-to-side manner. Having a transverse locking mechanism to interlock panels 10 together in a side-to-side manner is preferable to simply laying the panels 10 next to one another since interlocking provides improved protection of the underly-ing substrate from the elements. If desired, the transverse locking mechanism of each panel 10 can take a similar latching arrangement as the longitudinal locking mechanism described above. However, given that the longitudinal locking mechanism already serves to prevent upward movement of each of a system of interlocked panels 10, and given that fasteners through the nailing flange 20 already serve to restrain side-by-side movement, the transverse locking mechanism of the panels 10 can take a simpler form than the longitudinal locking mechanism if desired, and need not be a latching arrangement similar to the longitudinal locking mechanism. For example, the transverse 1~ locking mechanism of the panels 10 can take the form of a simple hook and lap arrangement.
Figures 1, 2, 3, and 13 show one possible embodiment of a transverse locking mechanism. In the example in Figures 1, 3, and 13, the transverse locking mechanism consists of a transverse protrusion extending upwardly from a panel 1~ along its right edge and a corre-sponding transverse cavity 40 on the underside of an adjacent panel 10 along its left edge. the transverse protrusion 3of one panel 1 interfits and interlocks with the transverse cavity of the adjacent panel 1to form an interlocking joint that resists moisture penetration of the system of interlocked panels 10. 'This transverse locking mecha~usm provides yet further protection against damaging water or moisture ingress into the underside of a system of interlocked panels 10.
Still further protection against the elements is preferably built into each panel 10 in the form of a reservoir cavity system located where the longitudinal locking mechanism of a panel 10 intersects the transverse locking mechanism. Referring to Figure 1, a recessed water reservoir 42 extends downwardly from the top of a panel 10 at its right, rear corner. Referring to Figure 3, a corresponding reservoir protrusion 44 extends downwardly from the underside of a panel 10 at its left, rear corner. The reservoir protrusion 44 of one panel 10 is adapted t~
interfit and interlock into the water reservoir 42 of an adjacent panel 10 to its left. The water reservoir 42 of one panel 10 cooperates with the reservoir protrusion 44 of the adjacent panel 10 to allow for the draining of any moisture that may penetrate or wick between the end of the longitudinal protrusion 28 of the first panel 10 and the opposing end of the longitudinal protrusion 28 of the adjacent panel 10. In particular, any such moisture in the water reservoir 42 drains down into an adjacent exposed drain gap 46 where it can simply run off the panel 10. The reservoir protrusion 44 interfits and interlocks into the adjacent water reservoir 42 to also create a tight bond and positioning mechanism, which assists to keep the ends of two adjacent panels ~0 in tight contact and position with respect to each other, especially in cooperation with the transverse locking mechanisms of those panels 10. The interlocking of the transverse protrusion ~8 and the transverse cavity 4also facili-tates additional alignment and tightness of placement between two adjacent panels ~~.
~f course, it will be realized that the transverse protrusion 38, the water reservoir 42, and the drain gap 6 could similarly be located on the left edge of the panel 1, in which case the corresponding transverse cavity 4and reservoir protrusion 44 would be located on the right edge of the panel 10. ~hs long as the transverse protrusion 38 is on an oppo-site side edge to the transverse cavity 40, and the water reservoir 42 and an adjacent drain gap 46 are on an opposite side edge to the reservoir protrusion 44, these elements will function as intended.
To install a system of panels 10, one should first remove any pre-existing cladding material from the underlying substrate or structure, and then cover the substrate with a suitable underlayment. Beginning at -IS-the lowest edge of the roof or other substrate, one should then install a ' starter strip (not shown) that replicates only the rearmost, normally not visible, portion of a panel 10. In particular, such a starter strip includes elements equivalent to the nailing flange 20, longitudinal protrusion 28, and water stop 36 of a panel 10, but not the decorative elements 12.
The starter strip can be, but need not be, the same length as the panels being used in the same installation; also, the starter strip can be, but need not be, made of the same material as the panels 10. For example, the starter strip may be made of metal and extruded in a greater length 10 than the panels 10 being used in the same installation, which may be made, for example, of a blend of rubber and plastic. The starter strip may also incorporate and integrate along its front edge a drip edge element, which would be similar to drip edges or gutter aprons typically installed along the eaves and/or gables of conventional roofs. ~s required, a series of such starter strips should be installed, by inserting one or more fasteners through the nailing flange of each starter strip, along the length of the edge of the substrate with the longitudinal protru-sion portion of each starter strip closest to tile edge of the substrate and the water stop portion farthest away.
after installing one ore more starter strips, as required, along the lowest edge of the substrate, a first row of panels 10 should then be interlocked to the installed starter strips by placing the indented region 32 of each of the row of panels lover the longitudinal protrusion and nailing flange portions of the starter strips and then pulling each of those panels 10 backward so as to engage the longitudinal locking mechanism by latching the longitudinal protrusions of the starter strips into the longitudinal cavities 30 of the panels 10. Each panel 10 in the row should also be transversely interlocked with any adjacent panel 10 in the row by interlocking the transverse protrusion 38 of each panel 10 into the transverse cavity 40 of the panel 10 to its right, and by interlocking the reservoir protrusion 44 of each panel 10 into the water reservoir 42 of the panel 10 to its left. Each of the panels 10 in the row should then be fastened to the substrate by inserting suitable fasteners through one or more of the recessed indicators 22 in the nailing flange 20. Once the first row of panels 10 has been installed, a second row can be installed by interfitting and interlocking the longitudinal cavities 30 of the panels in the second row to the longitudinal protrusions 28 of the panels 10 in the first row, and by transversely interlocking those panels 10 within the second row together in the same manner as the first row, preferably in a manner where the decorative elements 12 of the second row are 10 staggered with respect to the decorative elements 12 of the first row, and then fastening the second row of panels 10 to the substrate by inserting suitable fasteners through one or more of the recessed indica-tore in the nailing flanges 20 of the panels 10 in the second row. This procedure should be repeated for subsequent rows of panels 1L0 until the maderlying substrate has been covered. again, the panels 10 within each row should preferably be adjusted relative t~ panels 10 in adjacent rows to avoid any repeated patterns between adJacent rows that will result in an artificial overall appearance.
Figures 14 to 16 show longitudinally ~~lterlocked rows of trans-versely interlocked pan els 0 installed on a roof. Referring to Figures 14 to 16, wherever the underlying substrate or structure experiences a change in direction, such as a gable, ridge, hip, or valley (not Shown), which may result in any edges of panels 1being otherwise exposed, accessory caps incorporating similar design features to the panels 10 may be used to cover. those exposed edges. Referring to Figures 14 to 2~, such accessory caps may, for example, include ridge caps 50 for use along horizontal ridges of a roof, as well as on gables; hip caps 70 for inclined hips of a roof; valley caps (not shown) for horizontal or in-clined valleys of a roof; and edge caps (not shown) for edges of a roof (especially if the starter strip selected does not include an integrated drip edge). Such accessory caps, like the panels 10, may have simulated textures imparted to their visible surfaces if desired to provide the appearance of natural materials.
Figures 17 to 22 show a ridge cap 50 for installation along a ridge of a roof over systems of interlocked panels 10 on either side of the ridge, to protect the edges of those panels 10. Such a ridge cap 50 may also be used as a gable cap, to protect the edges of panels 10 where they end at a gable or rake of a roof. In the same manner as the panels 10, each ridge cap 50 has a nailing flange 52 with recessed indicators 54 to show preferred locations through which fasteners may be inserted to affix each ridge cap 50 to the underlying substrate. The nailing flange 52 is analogous to the nailing flange 20 of a panel 10. Deferring to Figures 17, 20, and 22, each ridge cap 50 has a ridge cap protrusion 56 extending upwardly and forwardly from its top surface in the same manner as the longitudinal protrusion 2~ of a panel ~0. Deferring to Figure 229 a corresponding ridge cap cavity 5~ in the underside of the ridge cap 50 is adapted to receive the ridge cap protrusion 56 of an adjacent ridge cap 5~. The ridge cap protrusion 5~ of a ridge cap 50 interfits and interlocks, in a latching manner, with the ridge cap cavity 5~ of the ridge cap 50 behind it, in a manner that protects the nailing flange 52 from the elements.
Similar to the panel 10, the ridge cap 50 is preferably not of solid construction, but rather has a network of longitudinal supports and transverse supports 62 which are slightly recessed from the bottom of the ridge cap 50 relative to the outer edges of the ridge cap 50 (in particular, the side edges). This provides both structural support and improved insulation value by providing an integrated blanket of air underneath a system of interlocked ridge caps 50 covering a ridge of the roof and the systems of interlocked panels 10 on either side of the ridge;
where used as a gable cap, this provides an integrated blanket of air underneath the system of interlocked ridge caps 50 covering the gable and the system of interlocked panels 10 that end at that gable.
-Ig-Figures 23 to 2~ show a hip cap 70 for installation along a hip of a roof over systems of interlocked panels 10 on either side of the hip, to protect the edges of those panels 10. Although each hip cap 70 has a hip cap cavity 78 in its front underside in the same manner that the ridge cap 50 has a ridge cap cavity 58 in its front underside, the hip cap 70 need not have a fixed, integrated corresponding protrusion near its rear top surface for latching with the hip cap cavity 78. Unlike the ridge cap 50 which is intended for a horizontal ridge, the hip cap 70 is intended for hips having a variety of possible pitches. Accordingly, a hip cap 70 which does not include an integrated latching protrusion near its rear edge, allows greater flexibility f~r adjustment to a variety of ro~f pitches. After each hip cap 70 has been adjusted to the particular pitch of the hip and installed on that hip, a separate removable locking mecha-nism (not shown) is installed near the rear edge of the hip cap 70, the 1 ~ separate removable locking mechanism having a protrusion adapted to interfit and interlock with the hip cap cavity 78. A subsequent hip cap 70 CaI1 then be interlocked behind that first hip cap 70 by interfitting and interlocking the hip cap cavity 78 ~f that subsequent hip cap 70 with the separate removable locl~ing mechanism installed onto the first hip cap 70. In other words, lzip cap °~0 has a hip cap protrusion that interfits and interlocks with its hip cap cavity 78, but that hip cap protrusion (unlike the ridge cap protrusion 5integrated into the ridge cap 50) is both removable from and re-attachable to the hip cap 7, in order to allow hip cap 70 to be easily adjusted to a wide variety of pitches of hips. While is it possible to manufacture the ridge cap 50 in a similar manner with a removable and re-attachable ridge cap protrusion 56, this would add an additional step into the installation of the ridge cap 50 and is typically unnecessary in respect of the installation of a ridge cap 50 onto a horizontal ridge or onto a gable.
Similar to the ridge cap 50 and the panel 10, the hip cap 70 is preferably not of solid construction, but rather has a network of trans-verse supports 82 which are slightly recessed from the bottom of the hip cap 70 relative to the outer edges of the hip cap 70 (in particular, the side edges); if desired, the hip cap. 70 can also have longitudinal sup-ports (not shown) similar to the ridge cap 50 and the panel 10. This provides both structural support and improved insulation value by providing an integrated blanket of air underneath the system of inter-locked hip caps 70 covering the hip of the roof and the systems of interlocked panels 10 on either side of the hip.
Like a panel 10, and for the same reasons set out above in respect of the panels 10, accessory caps like the ridge cap 50 and the hip cap 70 are preferably manufactured from a blend of recycled rubber tire crumb and recycled industrial polymers such as polyethylene and polypropy-lene or other virgin plastics. Even so, such accessory caps could conceivably be manufactured from any type of material or blend of materials, including rubber, plastic, fiberglass, metal, and/or other natural or synthetic materials.
The ridge cap 50 and hip cap 70 are preferably manufactured so that they are easily adjustable to any roofing application. Eor example, the ridge cap 50 is preferably formed in one piece, in the angles) most prevalent on sloped roof structures, but each ridge cap 50 preferably has a hinge ~4 along its longitudinal center for adjusting the ridge cap 50.
The hinge 64 is preferably simply a portion of the ridge cap 5along its longitudinal center that has been deliberately formed of lesser thickness than the "flaps" surrounding the hinge 64 on either side, in order to allow the ridge cap 50 to flex and adjust to various degrees larger or smaller than the prevalent angle(s). Preferably, the hinge 64 will permit adjustment of about between 10 to 20 degrees or more, but not so much that it degrades the strength of the ridge cap 50. The hip cap 70 prefer-ably has an analogous hinge 84 for adjusting the hip cap 70 in a similar manner as the ridge cap 50.
In conventional roofing applications, valley flashing is typically installed onto each valley of the roof or other substrate prior to installing the exterior roofing material, but no other covering is applied onto a valley after the exterior roofing material has been installed on either side of the valley. In respect of the present invention, valley flashing would similarly typically be installed onto a valley of the substrate prior to installing systems of interlocked panels 10 on either side of the valley.
Optionally, a system of interlocked accessory caps could also be in-stalled onto the valley after installing those systems of interlocked panels 10, to further protect the edges of the panels 10 that meet along the valley. As will be apparent to those skilled in the art in light of the descriptions above and drawings of the ridge cap 50 and the hip cap 70, a valley cap can be created for horizontal valleys by inverting the design of the ridge cap ~0 and for inclined valleys by inverting the design of the hip cap ~~. similarly, accessory caps could be created using the same principles for any edge of a roof, whether gabled or otherwise.
As will be further apparent to those skilled in the art in light of the examples in Figures 14 to 2~, accessory caps embodying aspects of the 111ventl~n can tale an infinite number of forms to suit any change in direction on the surface of a roof or other substr~.te or structure.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the scope thereof.

Description 'Throughout the following description specific details are set forth in order to provide a more thorough understanding of the invention.
T-lowever, the irwention may be practised without these particulars. In other instances, well known elements have not been shown or described in detail to avoid unnecessarily obscuring the present invention. Ac-cordingly, the specification and drawings are to be regarded in an illustrative, rather than a restrictive, sense.
Figure 1 is a top plan view and Figure 2 is a front elevation view of a panel 10 according to an embodiment of the invention. Each panel 10 is preferably manufactured from a blend of recycled rubber tire crumb and recycled industrial polymers such as polyethylene and polypropylene or other virgin plastics. Such a polymer and rubber matrix makes the panel 10 flexible and gives it a high coefficient of expansion and contraction; expansion and contraction will be minimal but the flexibility of the panel 10 makes it resistant to cracking or breaking. The preferred material composition also makes the panel 10 essentially impervious to water absorption or penetration. Being com-posed of recycled materials, a panel 10 with such a material composition may be an environmentally friendly and cost-competitive alternative to natural products. Additionally, such a material composition would make the panel 10 itself recyclable. If ever a panel 10 needed to be recycled, it can be simply re-ground and reprocessed. The durability and resistance to ultra-violet radiation of a panel 10 with such a material composition offer an extended life expectancy of about 50 years. A
panel 10 of such a material composition also has high insulation and sound dampening qualities. It is also lightweight, reducing the stress and structural pressures on any building on which the panel 10 is in-stalled.
Even so, a panel 10 according to the present invention could conceivably be manufactured from any type of material or blend of materials, including rubber, plastic, fiberglass, metal, and/or other natural or synthetic materials.
Although the most common usage of the panel i1is for roofing applications, it may also be used for other applications, such as siding.
Referring to Figures 1 and 2, a panel 10 according to an embodi-meat of the invention includes decorative elements 12, the top and frontal visible surfaces of which may be characterized by simulated textures of wood shakes (cedar or otherwise), slate, stone, brick, concrete tile, Spanish tile, Italian tile, other tile patterns, or any other effects. Many other designs may be imparted to the visible surfaces as may be required. The panel 10 may be colored to numerous synthetic colors to emulate natural colors - for example, greys, black, or browns .
Although each panel 10 is a unitary member, the decorative elements 12 are preferably separated by gaps 14 to give the appearance _7_ of discrete shakes, tiles, or other natural materials affixed adjacently.
The decorative elements 12 are preferably staggered so that their frontal faces 16 form an irregular pattern when viewed from the top. This irregular pattern avoids the artificial appearance that the frontal faces 16 would present if they were perfectly aligned. As noted, the frontal faces 16 may also have simulated textures imparted to them to provide integrity and consistency with corresponding simulated textures im-parted to the top surfaces 18 of the decorative elements 12.
Although each panel 10 could conceivably include just one decorative element 12, the panel 10 preferably includes a plurality of decorative elements 12. For example, each panel 10 can have a single row of three to five decorative elements 12 in the form of simulated 511akeS or tiles. A typical panel 10 with a single row of about three to five simulated shakes or tiles can be, for example, made about 16 in ches by 40 inches (40 cm. by 100 cn~.), with an exposed surface when installed of about three square feet (300 square cm.) and a thickness of about 1.g inches (4.5 cm.) at the thicl~est protrusion. A panel 10 of this approximate size, combined with the general lightweight nature of such panels 10, make the panels 10 easy to carry, position, align, and install, thereby cutting labor costs and installation times. It is possible for each panel 10 to have a plurality of rows of decorative elements 12 rather than just a single row. I~owever, if the overall size of the panel 1is to be maintained at about 16 inches by 40 inches (40 cm. by 100 cm.), each decorative element 12 would then need to be made smaller, which might be desirable for some applications but the decorative elements 12 might then no longer simulate the sizes and proportions of actual shakes and tiles commonly found in building applications. Alternatively, the size of the panel 10 can be made larger, but this should be balanced against having a panel 10 sized for optimal ease of carrying and installa-tion.
_g_ Referring to Figure 1, each panel 10 has a nailing flange 20 along its rear edge. The nailing flange 20 has recessed indicators 22 to show preferred locations where fasteners may be inserted to affix each panel to an underlying substrate. Fasteners, for example nails or screws, 5 may be used to fasten a panel 10 to a substrate or structure at one or more of each recessed indicator 22.
Figure 3 is a bottom plan view of a panel 10 according to an embodiment of the invention. As shown in Figure 3, a panel 10 accord-ing to this embodiment is not of solid construction, but is preferably 10 hollow other than a network of structural supports that run between the outer edges of the panel 10. In particular, a network of longitudinal supports 24 which run from one side of the panel 10 to the other side, and transverse supports 26 which run from the front of the panel 10 to the back, form an overall structure that allows for contact and support of the panel 1~ to the substrate to which it is fastened w1t11out the need for the panel 1to be completely solid. The structure formed by the longitudinal supports 24 and the transverse supports 2~ distributes any weight or forces of pressure that may be imparted to the top surface of any panels ~ 0 and evenly dissipates those pressures to the substrate, whether such pressures are caused by elemental forces such as wield or by someone walking on the panel 10, all without causing damage to the integrity of the panel for the substrate. The longitudinal supports 2 and transverse supports 2provide strength and integrity to each panel 1, but allow the panel 10 to be manufactured using less material, while achieving a more lightweight panel 10 that is both easier to install and easier for the substrate or underlying structure to support. The struc-tural supports need not be in a grid pattern as shown in Figure 3; any other pattern that similarly distributes weight and pressure will also be effective, although a grid pattern allows for simpler and more cost-effective manufacturing.
Referring to Figures 3, 5, and g, structural cavities 25 created by the multiple intersections of longitudinal supports 24 and transverse supports 26 also enhance the isolative qualities of the panel 10 by encapsulating pockets of air which become part of the natural insulation mechanism of the panel 10. Along with the thermal qualities of the composition of the preferred materials used in the manufacture of the panels 10 themselves, the air pockets within the plurality of structural cavities 25 give the panels 10 further isolative qualities which assist in cost savings in the heating and air conditioning of buildings on which panels 10 are interconnected into roofing or siding systems in hot or cold climatic areas.
As best shown in Figures 5 and ~, the longitudinal supports 24 and transverse supports 26 are preferably slightly recessed from the bottom of the panel X10 relative to the outer edges of the panel 10 - in 1~ particular, the side edges; this permits movement of the air pockets trapped under the panel 10. Accordingly, the slightly recessed longitu-dinal supports 24 and slightly recessed transverse supports 2~ together form a structure which both provides structural support to the panel 1 and assists in the dissipation of any built-up moisture underneath the panel 10 that may be created by moisture vapor which may percolate from the substrate or otherwise, thereby resisting damage caused by moisture in the form of damp rot, fungus or mold which proliferate in areas of dampness. In other words, the longitudinal supports 2and transverse supports 2provide both an effective support structure as well as an integrated venting system for the panels 10.
In addition, as shown in Figures 2, 3, and 5, a plurality of slots 27 in the bottom surface of each panel 10 near its front and rear edges connect air pockets that may otherwise be trapped beneath each panel 10 to pass to adjacent panels 10 to which they are connected, thereby creating a complete and integrated insulating air blanket under a system of interconnected panels 10 to further alleviate the chance of any mois-ture or vapor build up under a system of interconnected panels 10.
Such systems of interconnected panels 10 are shown in Figures 4 to 7. As shown in Figures 4 to 7, a plurality of panels 10 can be con-s nected together to form an interconnected system of panels, intercon-nected both in a side-to-side manner and in a front-to-back manner.
With respect to the front-to-back connectivity, each panel 10 has an element of a longitudinal locking mechanism along its length near each of its front and rear edges that allows it to interlock with an adjacent panel 10 in front of it or behind it. With respect to the side-to-side connectivity, each panel 10 preferably also has a transverse locking mechanism on its sides that allows it to interlock with an adjacent panel 10 to its side. both the longitudinal locking mechanism and the trans-verse locking mechanism will be described in more detail below.
Deferring to the cross-sectional side views of tl~ae panel 10 in Figures ~, 9, 11, and 12, a longitudinal protrusion 28 extends upwardly from the panel 10 in front of the nailing flange 2~, and forwardly toward the frontal faces 1. Referring to Figure 1, the longitudinal protrusion 28 preferably runs the length of the panel 10 near the rear edge of the panel 10 but in front of the nailing flange 20. Tllis longit~-dinal protrusion 28 forms one half of a longitudinal locking mechanism that permits a panel 10 to be longitudinally interlocked with an adjacent panel 1. In particular, the longitudinal protrusion 28 of one panel 1 interfits and interlocks with a corresponding longitudinal cavity 30 near the frontal faces 16 of an adjacent panel 1, as shown in Figures 11 and 12.
Referring to Figures 10 to 12, the underside of each panel 10 has an indented region 32 proximate to the frontal faces 16 of the panel 10.
The indented region 32 of each panel 10 is adapted to receive and encompass both the longitudinal protrusion 28 and the nailing flange 20 of the adjacent panel 10 in front of it. Each indented region 32 has within it a longitudinal cavity 30 which interfits with and interlocks, in a latching manner, with the longitudinal protrusion 28 of the adjacent panel 10 in front of it. During installation, after the frontmost of two adjacent panels 10 is fastened through its nailing flange 20 to the under-lying substrate, the indented region 32 of the rearmost of the two panels can be placed over both the longitudinal protrusion 28 and nailing flange 20 of the frontmost panel 10 and then pulled backwards until its longitudinal cavity 30 has interfitted and interlocked with the longitudi-nal protrusion 28 of the adjacent panel 10 in front of it. ~nce the 10 longitudinal cavity 30 of the rearmost panel 10 is interlocked in a latching manner with the longitudinal protrusion 28 of the adjacent panel 10 in front of it, the resulting longitudinal locking mechansm prevents the two interlocked panels 10 from moving perpendicularly away from each other. 'I'he indented region ~2 also, when the panel il0 is viewed from the side, encompasses and protects the nailing flange 20 of the panel tin front of it against elements such as water, wind, or wind-driven rain. Further, once the rearmost of the two panels 10 has also been fastened to the underlying substrate along its nailing flange 1, the 1~ngitudinal loclging mechanism prevents both bacl~ward movement of the panel 10 as well as upward movement that might otherwise be caused by wind uplift and rain near its frontal faces 16, without the need for additional fasteners near the front of the panel 1.
Deferring to Figures 3, 5, 7, ~, 10, and 12, further resistance to elemental forces is preferably provided by a plurality of additional cavities 3along the underside of the panel 1, running strategically along the full length of the frontal faces 16 of the panel 10. Each such cavity 34 creates a vacuum break which disrupts any wind-driven rain or water that may pass along the underside of the panel 10, thereby resisting the hazardous effect such elements could potentially cause, and draining the water naturally away.
Referring to Figure 12, any wind-driven rain or water that some-how penetrates under the panel 10 past the cavities 34 is then stopped by the longitudinal locking mechanism formed by the longitudinal cavity 30 of the panel 10 interfitting and interlocking with the longitudinal protru-sion 28 of the adjacent panel 10 in front of it, which together create a water-resistant joint which provides further resistance from wind-driven rain or other elements which might otherwise penetrate under the panel 10. This longitudinal locking mechanism also protects the nailing flange 20 of the front panel 10 and the fasteners used to secure that panel 10 through nailing flange 20 to the underlying substrate. For even further protection, as shown in Figures 8, 11 and 12, each panel 10 can have a water stop 36 along the full length of its rear edge behind its nailing flange 20, to further prevent moisture from penetrating past the water st~p 3to reach the underlying substrate. ~s shown in Figures 11 and 1 ~ 12, the longitudinal protrusion 28 of one panel interfits and interlocks with the longitudinal cavity 30 of an adjacent panel in a manner that adds strength to the system of interconnected panels 10 and that in-creases in strength with any exterior force that causes lift, such as wind.
As shown in Figures 4 to 7, the configuration of the longitudinal locl~ing mechanism, namely, a substantially continuous longitudinal protrusion 28 to which a corresponding longitudinal cavity 30 of one or more adjacent panels 10 can be latched at an indefinite number of points along the length of the longitudinal protrusion 28, allows for a continu-ous side-to-side adjustment of adjacent rows of interlocking panels 10 to achieve a laterally staggered effect, and prevent the proliferation of any ongoing noticeable repetitive design which may have a negative appeal to the look of the visual elements of the panels 10 when used in a system of such panels 10.
In addition to a longitudinal locking mechanism for allowing a plurality of panels 10 to be interlocked together in a front-to-back manner, a transverse locking mechanism is also desirable for allowing panels 10 to be interlocked together in a side-to-side manner. Having a transverse locking mechanism to interlock panels 10 together in a side-to-side manner is preferable to simply laying the panels 10 next to one another since interlocking provides improved protection of the underly-ing substrate from the elements. If desired, the transverse locking mechanism of each panel 10 can take a similar latching arrangement as the longitudinal locking mechanism described above. However, given that the longitudinal locking mechanism already serves to prevent upward movement of each of a system of interlocked panels 10, and given that fasteners through the nailing flange 20 already serve to restrain side-by-side movement, the transverse locking mechanism of the panels 10 can take a simpler form than the longitudinal locking mechanism if desired, and need not be a latching arrangement similar to the longitudinal locking mechanism. For example, the transverse 1~ locking mechanism of the panels 10 can take the form of a simple hook and lap arrangement.
Figures 1, 2, 3, and 13 show one possible embodiment of a transverse locking mechanism. In the example in Figures 1, 3, and 13, the transverse locking mechanism consists of a transverse protrusion extending upwardly from a panel 1~ along its right edge and a corre-sponding transverse cavity 40 on the underside of an adjacent panel 10 along its left edge. the transverse protrusion 3of one panel 1 interfits and interlocks with the transverse cavity of the adjacent panel 1to form an interlocking joint that resists moisture penetration of the system of interlocked panels 10. 'This transverse locking mecha~usm provides yet further protection against damaging water or moisture ingress into the underside of a system of interlocked panels 10.
Still further protection against the elements is preferably built into each panel 10 in the form of a reservoir cavity system located where the longitudinal locking mechanism of a panel 10 intersects the transverse locking mechanism. Referring to Figure 1, a recessed water reservoir 42 extends downwardly from the top of a panel 10 at its right, rear corner. Referring to Figure 3, a corresponding reservoir protrusion 44 extends downwardly from the underside of a panel 10 at its left, rear corner. The reservoir protrusion 44 of one panel 10 is adapted t~
interfit and interlock into the water reservoir 42 of an adjacent panel 10 to its left. The water reservoir 42 of one panel 10 cooperates with the reservoir protrusion 44 of the adjacent panel 10 to allow for the draining of any moisture that may penetrate or wick between the end of the longitudinal protrusion 28 of the first panel 10 and the opposing end of the longitudinal protrusion 28 of the adjacent panel 10. In particular, any such moisture in the water reservoir 42 drains down into an adjacent exposed drain gap 46 where it can simply run off the panel 10. The reservoir protrusion 44 interfits and interlocks into the adjacent water reservoir 42 to also create a tight bond and positioning mechanism, which assists to keep the ends of two adjacent panels ~0 in tight contact and position with respect to each other, especially in cooperation with the transverse locking mechanisms of those panels 10. The interlocking of the transverse protrusion ~8 and the transverse cavity 4also facili-tates additional alignment and tightness of placement between two adjacent panels ~~.
~f course, it will be realized that the transverse protrusion 38, the water reservoir 42, and the drain gap 6 could similarly be located on the left edge of the panel 1, in which case the corresponding transverse cavity 4and reservoir protrusion 44 would be located on the right edge of the panel 10. ~hs long as the transverse protrusion 38 is on an oppo-site side edge to the transverse cavity 40, and the water reservoir 42 and an adjacent drain gap 46 are on an opposite side edge to the reservoir protrusion 44, these elements will function as intended.
To install a system of panels 10, one should first remove any pre-existing cladding material from the underlying substrate or structure, and then cover the substrate with a suitable underlayment. Beginning at -IS-the lowest edge of the roof or other substrate, one should then install a ' starter strip (not shown) that replicates only the rearmost, normally not visible, portion of a panel 10. In particular, such a starter strip includes elements equivalent to the nailing flange 20, longitudinal protrusion 28, and water stop 36 of a panel 10, but not the decorative elements 12.
The starter strip can be, but need not be, the same length as the panels being used in the same installation; also, the starter strip can be, but need not be, made of the same material as the panels 10. For example, the starter strip may be made of metal and extruded in a greater length 10 than the panels 10 being used in the same installation, which may be made, for example, of a blend of rubber and plastic. The starter strip may also incorporate and integrate along its front edge a drip edge element, which would be similar to drip edges or gutter aprons typically installed along the eaves and/or gables of conventional roofs. ~s required, a series of such starter strips should be installed, by inserting one or more fasteners through the nailing flange of each starter strip, along the length of the edge of the substrate with the longitudinal protru-sion portion of each starter strip closest to tile edge of the substrate and the water stop portion farthest away.
after installing one ore more starter strips, as required, along the lowest edge of the substrate, a first row of panels 10 should then be interlocked to the installed starter strips by placing the indented region 32 of each of the row of panels lover the longitudinal protrusion and nailing flange portions of the starter strips and then pulling each of those panels 10 backward so as to engage the longitudinal locking mechanism by latching the longitudinal protrusions of the starter strips into the longitudinal cavities 30 of the panels 10. Each panel 10 in the row should also be transversely interlocked with any adjacent panel 10 in the row by interlocking the transverse protrusion 38 of each panel 10 into the transverse cavity 40 of the panel 10 to its right, and by interlocking the reservoir protrusion 44 of each panel 10 into the water reservoir 42 of the panel 10 to its left. Each of the panels 10 in the row should then be fastened to the substrate by inserting suitable fasteners through one or more of the recessed indicators 22 in the nailing flange 20. Once the first row of panels 10 has been installed, a second row can be installed by interfitting and interlocking the longitudinal cavities 30 of the panels in the second row to the longitudinal protrusions 28 of the panels 10 in the first row, and by transversely interlocking those panels 10 within the second row together in the same manner as the first row, preferably in a manner where the decorative elements 12 of the second row are 10 staggered with respect to the decorative elements 12 of the first row, and then fastening the second row of panels 10 to the substrate by inserting suitable fasteners through one or more of the recessed indica-tore in the nailing flanges 20 of the panels 10 in the second row. This procedure should be repeated for subsequent rows of panels 1L0 until the maderlying substrate has been covered. again, the panels 10 within each row should preferably be adjusted relative t~ panels 10 in adjacent rows to avoid any repeated patterns between adJacent rows that will result in an artificial overall appearance.
Figures 14 to 16 show longitudinally ~~lterlocked rows of trans-versely interlocked pan els 0 installed on a roof. Referring to Figures 14 to 16, wherever the underlying substrate or structure experiences a change in direction, such as a gable, ridge, hip, or valley (not Shown), which may result in any edges of panels 1being otherwise exposed, accessory caps incorporating similar design features to the panels 10 may be used to cover. those exposed edges. Referring to Figures 14 to 2~, such accessory caps may, for example, include ridge caps 50 for use along horizontal ridges of a roof, as well as on gables; hip caps 70 for inclined hips of a roof; valley caps (not shown) for horizontal or in-clined valleys of a roof; and edge caps (not shown) for edges of a roof (especially if the starter strip selected does not include an integrated drip edge). Such accessory caps, like the panels 10, may have simulated textures imparted to their visible surfaces if desired to provide the appearance of natural materials.
Figures 17 to 22 show a ridge cap 50 for installation along a ridge of a roof over systems of interlocked panels 10 on either side of the ridge, to protect the edges of those panels 10. Such a ridge cap 50 may also be used as a gable cap, to protect the edges of panels 10 where they end at a gable or rake of a roof. In the same manner as the panels 10, each ridge cap 50 has a nailing flange 52 with recessed indicators 54 to show preferred locations through which fasteners may be inserted to affix each ridge cap 50 to the underlying substrate. The nailing flange 52 is analogous to the nailing flange 20 of a panel 10. Deferring to Figures 17, 20, and 22, each ridge cap 50 has a ridge cap protrusion 56 extending upwardly and forwardly from its top surface in the same manner as the longitudinal protrusion 2~ of a panel ~0. Deferring to Figure 229 a corresponding ridge cap cavity 5~ in the underside of the ridge cap 50 is adapted to receive the ridge cap protrusion 56 of an adjacent ridge cap 5~. The ridge cap protrusion 5~ of a ridge cap 50 interfits and interlocks, in a latching manner, with the ridge cap cavity 5~ of the ridge cap 50 behind it, in a manner that protects the nailing flange 52 from the elements.
Similar to the panel 10, the ridge cap 50 is preferably not of solid construction, but rather has a network of longitudinal supports and transverse supports 62 which are slightly recessed from the bottom of the ridge cap 50 relative to the outer edges of the ridge cap 50 (in particular, the side edges). This provides both structural support and improved insulation value by providing an integrated blanket of air underneath a system of interlocked ridge caps 50 covering a ridge of the roof and the systems of interlocked panels 10 on either side of the ridge;
where used as a gable cap, this provides an integrated blanket of air underneath the system of interlocked ridge caps 50 covering the gable and the system of interlocked panels 10 that end at that gable.
-Ig-Figures 23 to 2~ show a hip cap 70 for installation along a hip of a roof over systems of interlocked panels 10 on either side of the hip, to protect the edges of those panels 10. Although each hip cap 70 has a hip cap cavity 78 in its front underside in the same manner that the ridge cap 50 has a ridge cap cavity 58 in its front underside, the hip cap 70 need not have a fixed, integrated corresponding protrusion near its rear top surface for latching with the hip cap cavity 78. Unlike the ridge cap 50 which is intended for a horizontal ridge, the hip cap 70 is intended for hips having a variety of possible pitches. Accordingly, a hip cap 70 which does not include an integrated latching protrusion near its rear edge, allows greater flexibility f~r adjustment to a variety of ro~f pitches. After each hip cap 70 has been adjusted to the particular pitch of the hip and installed on that hip, a separate removable locking mecha-nism (not shown) is installed near the rear edge of the hip cap 70, the 1 ~ separate removable locking mechanism having a protrusion adapted to interfit and interlock with the hip cap cavity 78. A subsequent hip cap 70 CaI1 then be interlocked behind that first hip cap 70 by interfitting and interlocking the hip cap cavity 78 ~f that subsequent hip cap 70 with the separate removable locl~ing mechanism installed onto the first hip cap 70. In other words, lzip cap °~0 has a hip cap protrusion that interfits and interlocks with its hip cap cavity 78, but that hip cap protrusion (unlike the ridge cap protrusion 5integrated into the ridge cap 50) is both removable from and re-attachable to the hip cap 7, in order to allow hip cap 70 to be easily adjusted to a wide variety of pitches of hips. While is it possible to manufacture the ridge cap 50 in a similar manner with a removable and re-attachable ridge cap protrusion 56, this would add an additional step into the installation of the ridge cap 50 and is typically unnecessary in respect of the installation of a ridge cap 50 onto a horizontal ridge or onto a gable.
Similar to the ridge cap 50 and the panel 10, the hip cap 70 is preferably not of solid construction, but rather has a network of trans-verse supports 82 which are slightly recessed from the bottom of the hip cap 70 relative to the outer edges of the hip cap 70 (in particular, the side edges); if desired, the hip cap. 70 can also have longitudinal sup-ports (not shown) similar to the ridge cap 50 and the panel 10. This provides both structural support and improved insulation value by providing an integrated blanket of air underneath the system of inter-locked hip caps 70 covering the hip of the roof and the systems of interlocked panels 10 on either side of the hip.
Like a panel 10, and for the same reasons set out above in respect of the panels 10, accessory caps like the ridge cap 50 and the hip cap 70 are preferably manufactured from a blend of recycled rubber tire crumb and recycled industrial polymers such as polyethylene and polypropy-lene or other virgin plastics. Even so, such accessory caps could conceivably be manufactured from any type of material or blend of materials, including rubber, plastic, fiberglass, metal, and/or other natural or synthetic materials.
The ridge cap 50 and hip cap 70 are preferably manufactured so that they are easily adjustable to any roofing application. Eor example, the ridge cap 50 is preferably formed in one piece, in the angles) most prevalent on sloped roof structures, but each ridge cap 50 preferably has a hinge ~4 along its longitudinal center for adjusting the ridge cap 50.
The hinge 64 is preferably simply a portion of the ridge cap 5along its longitudinal center that has been deliberately formed of lesser thickness than the "flaps" surrounding the hinge 64 on either side, in order to allow the ridge cap 50 to flex and adjust to various degrees larger or smaller than the prevalent angle(s). Preferably, the hinge 64 will permit adjustment of about between 10 to 20 degrees or more, but not so much that it degrades the strength of the ridge cap 50. The hip cap 70 prefer-ably has an analogous hinge 84 for adjusting the hip cap 70 in a similar manner as the ridge cap 50.
In conventional roofing applications, valley flashing is typically installed onto each valley of the roof or other substrate prior to installing the exterior roofing material, but no other covering is applied onto a valley after the exterior roofing material has been installed on either side of the valley. In respect of the present invention, valley flashing would similarly typically be installed onto a valley of the substrate prior to installing systems of interlocked panels 10 on either side of the valley.
Optionally, a system of interlocked accessory caps could also be in-stalled onto the valley after installing those systems of interlocked panels 10, to further protect the edges of the panels 10 that meet along the valley. As will be apparent to those skilled in the art in light of the descriptions above and drawings of the ridge cap 50 and the hip cap 70, a valley cap can be created for horizontal valleys by inverting the design of the ridge cap ~0 and for inclined valleys by inverting the design of the hip cap ~~. similarly, accessory caps could be created using the same principles for any edge of a roof, whether gabled or otherwise.
As will be further apparent to those skilled in the art in light of the examples in Figures 14 to 2~, accessory caps embodying aspects of the 111ventl~n can tale an infinite number of forms to suit any change in direction on the surface of a roof or other substr~.te or structure.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the scope thereof.
Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
