Definitions
- the present invention relates generally to roofing shingles, and more particularly, to multi-layered shingles that are configured to permit the shingle to be bent, such as over an apex of a roof.
- Roofs are typically formed so as to present at least two non-parallel planes that meet at a peak, usually the uppermost point of the roof. This peak is typically referred to as the ridge. Roofs can also be formed to present other non-parallel planes that are often formed at the ends of the ridge to form other diagonally-extending plane intersections similar to the ridge, but are referred to as hips. Whereas, the covering of the planar portions of a roof typically involve the laying of shingles in overlapping, transversely parallel courses from the bottom roof edge to the ridge or hip, the ridges and hips require a different technique to cover the intersection of the two or more roof planes.
- a conventional technique for covering the ridges and hips is to cut the shingles into appropriate width and to bend the cut shingle over the ridge or hip so as to overlap the shingles placed on the opposing roof planes, and then starting at one end of the ridge or hip and overlap the cut shingles along the length of the ridge or hip.
- Asphalt composite shingles are one of the most commonly used roofing products. These asphalt composite shingles typically incorporate a base material made from a fiberglass mat, or other suitable reinforcement member, such as an organic felt material. This reinforcing base material serves as a matrix to support an asphalt coating and gives the shingle strength.
- the asphalt coating is formulated for the particular service application and has a long-term ability to resist weathering and provide stability for the structure under extreme temperature conditions.
- An outer layer of granules is applied to the asphalt coating to form an outer surface that the asphalt coating from direct sunlight. Utilizing differently colored granules provides a variety in the surface appearance of the shingle to establish color variations.
- Conventional laminated shingles for example, as well as hip and ridge shingles, are generally multilayered and the separate, individual layers are held together with an adhesive material.
- Hip and ridge shingles are disclosed by the present patent application.
- the hip and ridge shingles may be single layer or laminated (i.e. more than one layer adhered on top of one another).
- a laminated hip and ridge shingle includes a base layer and a dimensional layer.
- the dimensional layer is affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers.
- the adhesive line is disposed on only one lateral side of the base layer and dimensional layers to allow movement of another lateral side of the dimensional layer relative to the base layer.
- a laminated hip and ridge shingle includes a base layer and a dimensional layer.
- the dimensional layer is affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers.
- Sealant that comprises one line or two or more parallel lines of sealant material that extend in the machine direction of the base and dimensional layers is disposed on a bottom surface of the base layer for adhering the hip and ridge shingle to an underlying hip and ridge shingle.
- a hip and ridge shingle includes a granule coated asphalt substrate, sealant on the substrate, and release tape on the substrate.
- the sealant comprises one line or two or more parallel lines of sealant material that extend in a direction of a width of the substrate for adhering the hip and ridge shingle to an underlying hip and ridge shingle.
- the release tape is disposed on a bottom of the substrate that is alignable with the at least two parallel lines of sealant when two of the hip and ridge shingles are stacked to prevent the two hip and ridge shingles from sticking together.

- the building structure 110 has a plurality of roof planes 114 a - 114 d .
- the term “roof plane” as used herein is defined to mean a plane defined by a flat portion of the roof formed by an area of roof deck.
- Each of the roof planes 114 a - 114 d has a slope.
- the term “slope” as used herein is defined to mean the degree of incline of the roof plane. While the roof planes 114 a - 114 d shown in FIG. 1A have their respective illustrated slopes, it should be understood that the roof planes 114 a - 114 d can have any suitable slope.
- the intersection of the roof planes 114 b and 114 c form a hip 116 .
- the term “hip” as used herein is defined to mean the inclined external angle formed by the intersection of two sloping roof planes. Similarly, the intersection of the roof planes 114 b and 114 d form a ridge 118 .
- the term “ridge” as used herein is defined to mean the uppermost horizontal external angle formed by the intersection of two sloping roof planes.
- the building structure 110 is covered by the roofing system 112 having a plurality of shingles 120 .
- the shingles 120 may be asphalt-based roofing material of the type disclosed in U.S. Pat. No. 6,709,994 to Miller et al., which is incorporated by reference, in its entirety.

Abstract
Description
- This application is a divisional application of U.S. Ser. No. 14/188,957, filed on Feb. 25, 2014 titled “Laminated Hip and Ridge Shingle”, the entire disclosure of which is incorporated herein in its entirety.
- The present invention relates generally to roofing shingles, and more particularly, to multi-layered shingles that are configured to permit the shingle to be bent, such as over an apex of a roof.
- Roofs are typically formed so as to present at least two non-parallel planes that meet at a peak, usually the uppermost point of the roof. This peak is typically referred to as the ridge. Roofs can also be formed to present other non-parallel planes that are often formed at the ends of the ridge to form other diagonally-extending plane intersections similar to the ridge, but are referred to as hips. Whereas, the covering of the planar portions of a roof typically involve the laying of shingles in overlapping, transversely parallel courses from the bottom roof edge to the ridge or hip, the ridges and hips require a different technique to cover the intersection of the two or more roof planes. A conventional technique for covering the ridges and hips is to cut the shingles into appropriate width and to bend the cut shingle over the ridge or hip so as to overlap the shingles placed on the opposing roof planes, and then starting at one end of the ridge or hip and overlap the cut shingles along the length of the ridge or hip.
- Asphalt composite shingles are one of the most commonly used roofing products. These asphalt composite shingles typically incorporate a base material made from a fiberglass mat, or other suitable reinforcement member, such as an organic felt material. This reinforcing base material serves as a matrix to support an asphalt coating and gives the shingle strength. The asphalt coating is formulated for the particular service application and has a long-term ability to resist weathering and provide stability for the structure under extreme temperature conditions. An outer layer of granules is applied to the asphalt coating to form an outer surface that the asphalt coating from direct sunlight. Utilizing differently colored granules provides a variety in the surface appearance of the shingle to establish color variations.
- Conventional laminated shingles, for example, as well as hip and ridge shingles, are generally multilayered and the separate, individual layers are held together with an adhesive material.
- Hip and ridge shingles are disclosed by the present patent application. The hip and ridge shingles may be single layer or laminated (i.e. more than one layer adhered on top of one another). In one exemplary embodiment, a laminated hip and ridge shingle includes a base layer and a dimensional layer. The dimensional layer is affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers. The adhesive line is disposed on only one lateral side of the base layer and dimensional layers to allow movement of another lateral side of the dimensional layer relative to the base layer.
- In one exemplary embodiment, a laminated hip and ridge shingle includes a base layer and a dimensional layer. The dimensional layer is affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers. Sealant that comprises one line or two or more parallel lines of sealant material that extend in the machine direction of the base and dimensional layers is disposed on a bottom surface of the base layer for adhering the hip and ridge shingle to an underlying hip and ridge shingle.
- In one exemplary embodiment, a hip and ridge shingle includes a granule coated asphalt substrate, sealant on the substrate, and release tape on the substrate. The sealant comprises one line or two or more parallel lines of sealant material that extend in a direction of a width of the substrate for adhering the hip and ridge shingle to an underlying hip and ridge shingle. The release tape is disposed on a bottom of the substrate that is alignable with the at least two parallel lines of sealant when two of the hip and ridge shingles are stacked to prevent the two hip and ridge shingles from sticking together.
- In the accompanying drawings which are incorporated in and constitute a part of the specification, embodiments of the invention are illustrated, which together with a general description of the invention given above and the detailed description given below, serve to example the principles of this invention.

All references cited herein, including published or corresponding U.S. or foreign patent applications, issued U.S. or foreign patents, or any other references, are each incorporated by reference in their entireties, including all data, tables, figures, and text presented in the cited references. The terms “cap shingle”, “cap”, or “hip and ridge shingle” may be used interchangeably herein.
- The description and drawings disclose exemplary embodiments of hip and
ridge shingles 10. With reference toFIG. 1A , abuilding structure 110 is shown having a shingle-basedroofing system 112. While thebuilding structure 110 illustrated inFIG. 1A is a residential home, it should be understood that thebuilding structure 110 can be any type of structure, such as a garage, church, arena or commercial building, having a shingle-basedroofing system 112. - The
building structure 110 has a plurality of roof planes 114 a-114 d. The term “roof plane” as used herein is defined to mean a plane defined by a flat portion of the roof formed by an area of roof deck. Each of the roof planes 114 a-114 d has a slope. The term “slope” as used herein is defined to mean the degree of incline of the roof plane. While the roof planes 114 a-114 d shown inFIG. 1A have their respective illustrated slopes, it should be understood that the roof planes 114 a-114 d can have any suitable slope. The intersection of the roof planes 114 b and 114 c form ahip 116. The term “hip” as used herein is defined to mean the inclined external angle formed by the intersection of two sloping roof planes. Similarly, the intersection of the roof planes 114 b and 114 d form aridge 118. The term “ridge” as used herein is defined to mean the uppermost horizontal external angle formed by the intersection of two sloping roof planes. - The
building structure 110 is covered by theroofing system 112 having a plurality ofshingles 120. In the illustrated embodiment, theshingles 120 may be asphalt-based roofing material of the type disclosed in U.S. Pat. No. 6,709,994 to Miller et al., which is incorporated by reference, in its entirety. As shown inFIG. 1B , theshingles 120 are installed on the various roof decks in generally horizontal courses 122 a-122 g in which theshingles 120 overlap the shingles of a preceding course. - Hip and
ridge shingles 10 are installed to protect hips and ridges from the elements. As shown inFIG. 1B , hip andridge shingles 10 are installed on theridge 118 and over theshingles 120. In a similar fashion, hip and ridge shingles are installed on a hip (not shown) and over the shingles. - Referring to
FIG. 1 , an exemplary embodiment of a laminated hip andridge shingle 10 is shown. Thelaminated shingle 10 includes abase layer 12 and adimensional layer 14. Thebase layer 12 and thedimensional layer 14 can be made in a wide variety of different ways. For example, each of the layers can be made in the same manner that conventional single layer shingles are made. That is, asphalt is applied to a fiberglass mat, and granules are applied the asphalt. - Referring to
FIGS. 2 and 3 , in an exemplary embodiment, abottom surface 18 of thedimensional layer 14 is adhered to thetop surface 19 of thebase layer 12 by an adhesive 20. In the illustrated embodiment, the adhesive 20 extends only partially across the overlap between thebase layer 12 and thedimensional layer 14. In the illustrated embodiments, the adhesive is disposed on only one lateral side of the base and dimensional layers. Referring toFIG. 1B , the portion of thebase layer 12 that is not covered by thedimensional layer 14 is the portion of the shingle that will be exposed on the ridge of the roof. Thedimensional layer 14 will be completely covered by thebase layer 12 of the next shingle applied to theridge 118. Thedimensional layer 14 increases the thickness of the overlapping portions of twoshingles 10. This provides theridge 118 with a more dimensional appearance. - In the exemplary embodiment illustrated by
FIG. 3 , the entiredimensional layer 14 is on top of the base layer 12 (i.e. complete overlap). This complete overlap reduces the possibility that water can pass between thelayers FIGS. 9-11 , by having the adhesive 20 extend only partially across the overlap between the first and second layers and on only one lateral side of the shingle, theshingle 10 can be bent over theridge 118 of the roof without tearing, buckling or otherwise damaging the top layer.FIGS. 10 and 11 illustrate that the portion of thedimensional layer 14 that is not adhered to thebase layer 12 is able to slide or laterally move with respect to thebase layer 12. This sliding or lateral movement allows thelaminated shingle 10 to be bent over aroof ridge 118 without damaging thedimensional layer 14. - Referring to
FIGS. 1 and 3 , an optional nailzone reinforcement material 35 is provided. The nailzone reinforcement material 35 can take a wide variety of different forms and can be applied to the laminated shingle at a wide variety positions. For example, the nailzone reinforcement material 35 can be a woven fabric, a plastic film, a metal strip, applied paint, and the like. The nailzone reinforcement material 35 can be provided on top of thedimensional layer 14, on the bottom of the dimensional layer, on top of thebase layer 12, on the bottom of thebase layer 12, or inside the base layer or dimensional layer. A nail line marking or other indicia may be provided on top of thedimensional layer 14 when nail line reinforcement material is not provided on the top layer. More than one nail zone reinforcement material may be provided. U.S. Pat. No. 8,607,521 discloses examples of nail zone reinforcement materials, methods of applying nail zone reinforcement materials to shingles, and shingles having reinforced nail zones that can be adapted into theshingles 10 disclosed by the present application. U.S. Pat. No. 8,607,521 is incorporated herein by reference in its entirety. In the illustrated embodiment, the nailzone reinforcement material 35 is a woven fabric that prevents the shingle from being pulled over a nail-head that secures the shingle to the roof. - Referring to
FIGS. 7 and 8 , in an exemplary embodiment adhesive and/orsealant lines 40 and/or 42 are provided on the bottom of thebase layer 12. When a shingle is installed over another shingle on the roof ridge, theadhesive lines 40 and/or 42 adhere to the upper surface of thedimensional layer 14 to secure the shingles together. Theadhesive lines 40 and/or 42 can have a wide variety of different configurations. In the exemplary embodiment illustrated byFIG. 7 , theadhesive line 40 extends along substantially an entire width and is close to anedge 700 of thebase layer 12.

In an exemplary embodiment, theadhesive lines 42 are positioned to adhere togranules 702 and to thereinforcement material 35 on thedimensional layer 14. In an exemplary embodiment, the sealant configuration illustrated byFIG. 8 provides enhanced resistant to the shingle edge pulling up due to wind that blows in a direction perpendicular to theside edge shingle 10. - Referring to
FIGS. 7 and 8 , arelease tape 50 is provided on the back side of thebase layer 12. The laminated hip andridge shingles 10 are flipped over and turned 180 degrees when they are packaged, so that therelease tape 50 lines up with theadhesive lines release tape 50 prevents the shingles from sticking together in the package. Therelease tape 50 can take a wide variety of different forms. - Referring to
FIGS. 4-6 , the hip andridge shingles 10 are constructed by cutting a single layer granule coatedsubstrate 16 or shingle blank into pieces to make thebase layer 12 and thedimensional layer 14. In the illustrated embodiment, the shingle blank 16 includes aheadlap region 428 and aprime region 430. Theheadlap region 428 of the shingle blank 426 is used to make thedimensional layer 14. Theprime region 430 of the shingle blank 426 is the portion of the hip or ridge roofing material that remains exposed when the hip andridge shingles 10 are installed. In one exemplary embodiment, the entire front surface of the shingle blank 426 is coated with prime roofing granules and the entire rear surface of the shingle blank 426 is covered with headlap granules. - Referring again to
FIG. 4 , the shingle blank 16 may have any suitable dimensions. The shingle blank 426 may also be divided between theheadlap region 428 and theprime region 430 in any suitable proportion. For example, a typical residential roofing shingle blank 16 has a length L of approximately 36 inches (91.5 cm) and a height H of approximately 13¼ inches high, with the height H dimension being divided between theheadlap region 428 and theprime region 430. - In one exemplary embodiment, the shingle blank 16 has the same composition as the incorporated '994 patent to Miller et al. In another embodiment, the shingle blank can have other suitable compositions. The shingle blank 16 includes a substrate that is coated with an asphalt coating. The asphalt coating includes an upper section that is positioned above the substrate when the roofing material is installed on a roof, and a lower section that is positioned below the substrate. The upper section includes an upper surface. Referring to
FIGS. 4 and 5 , in an exemplary embodiment, the nailzone reinforcement material 35 is pressed into the upper section of the asphalt coating to embed the nailzone reinforcement material 35 in the asphalt. A layer ofgranules 702 is then pressed into the upper section asphalt coating. In an exemplary embodiment, the layer ofgranules 702 do not stick to the nailzone reinforcement material 35. Therelease tape 50 is pressed against the lower section of the asphalt coating. A layer ofgranules 702 or a layer of back dusting is then pressed into the lower section asphalt coating. In an exemplary embodiment, the layer ofgranules 702 or back dusting do not stick to therelease tape 50. In an exemplary embodiment,granules 702 are used on both sides of the shingle blank 16 to make the laminated hip and ridge shingle thicker. - Referring to
FIGS. 4-6 , in an exemplary embodiment a single layer shingle layer or blank 16 is cut up and assembled to make the laminated shingle. In this example, the laminated shingle will typically be assembled in an off-line process. That is, the laminated shingles are not produced in a continuous line. In an exemplary embodiment, the blank is cut as shown inFIG. 6 . The dimensional layers 14 may be about 11 inches wide. Thebase layer 12 may be about 12 inches wide withscallop cuts 450 at the end with therelease tape 50 that reduce the width to about 11 inches at the scallop cuts. The base layer is flipped over and adhesive 20 is applied partially across the base layer as illustrated byFIG. 2 . Thedimensional layer 14 is then adhered to the adhesive 20 as illustrated byFIG. 3 . Theshingle 10 is then flipped over and thesealant FIG. 7 orFIG. 8 to complete the shingle. Theshingles 10 are then alternately flipped and stacked, such that thesealant release tape 50 and the shingles do not stick together. In another exemplary embodiment, the laminated shingles are assembled in an inline process on a continuous production line. - In an exemplary embodiment, the scallop cuts 450 and the narrower width
dimensional layer 14 keep the nailzone reinforcement material 35 from being exposed when theshingle 10 is installed on a roof as illustrated byFIGS. 1B and 11 . That is, thebase layer 12 of an overlying shingle completely covers thedimensional layer 14 of the underlying shingle, due to the narrower width of thedimensional layer 14. - The shingle blank 16 can be made in a wide variety of different ways. In one exemplary embodiment, a process and apparatus that may be adapted to be used to manufacture the single
layer shingle blank 16 is described in U.S. Pat. No. 8,607,521 to Belt et al. and is only summarized herein. There is shown inFIG. 28 anapparatus 2810 for manufacturing an asphalt-based roofing material. In the illustrated embodiment, the manufacturing process involves passing acontinuous sheet 2812 in a machine direction (indicated by the arrows) through a series of manufacturing operations. The sheet usually moves at a speed of at least about 200 feet/minute (61 meters/minute), and typically at a speed within the range of between about 450 feet/minute (137 meters/minute) and about 800 feet/minute (244 meters/minute). In one exemplary embodiment, the sheet moves at a speed of at least about 200 feet/minute (61 meters/minute), and less than about 450 feet/minute (137 meters/minute). The sheet, however, may move at any desired speed. - In a first step of the illustrated manufacturing process, a continuous sheet of substrate or
shingle mat 2812 is payed out from a roll 2814. The substrate can be any type known for use in reinforcing asphalt-based roofing materials, such as a non-woven web of glass fibers. Theshingle mat 2812 may be fed through a coater 2816 where an asphalt coating is applied to themat 2812. The asphalt coating can be applied in any suitable manner. In the illustrated embodiment, themat 2812 contacts aroller 2817, that is in contact with a supply of hot, melted asphalt. Theroller 2817 completely covers themat 2812 with a tacky coating of hot, melted asphalt to define a first asphalt coated sheet 2818. In other embodiments, however, the asphalt coating could be sprayed on, rolled on, or applied to the sheet by other means. - A continuous strip of a reinforcement material or
tape 35, as will be described in detail herein, may then be payed out from aroll 2820. Thereinforcement tape 35 adheres to the asphalt coated sheet 2818. In one embodiment, thereinforcement tape 35 is attached to the sheet 2818 by the adhesive mixture of the asphalt in the asphalt coated sheet 2818. Thereinforcement tape 35, however, may be attached to the sheet 2818 by any suitable means, such as other adhesives. In one embodiment, thereinforcement material 35 is formed from polyester. In another embodiment, the reinforcement material is formed from polyolefin, such as polypropylene or polyethylene. Thereinforcement material 35, however, can be formed from any material for reinforcing and strengthening the nail zone of a shingle, such as, for example, paper, film, scrim material, and woven or non-woven glass. - The resulting asphalt coated sheet may then be passed beneath a series of granule dispensers 2824 for the application of granules to the upper surface of the asphalt coated sheet 2818. The granule dispensers can be of any type suitable for depositing granules onto the asphalt coated sheet. A granule dispenser that can be used is a granule valve of the type disclosed in U.S. Pat. No. 6,610,147 to Aschenbeck. After all the granules are deposited on the asphalt coated sheet by the series of dispensers 2824, the sheet 2818 becomes a granule covered sheet 2840.
- In one embodiment, the
reinforcement material 35 includes an upper surface to which granules substantially will not adhere. Thereinforcement material 35, however, may include an upper surface to which granules will adhere. For example, theapparatus 2810 may include any desired means for depositing granules onto substantially the entire second asphalt coated sheet 2818, except for the portion of the second asphalt coated sheet 2818 covered by thematerial 35. Alternately, granules may be deposited onto substantially the entire asphalt coated sheet 2818, including thematerial 35, but wherein thereinforcement material 35 includes an upper surface to which granules substantially will not adhere. - The granule covered
sheet 40 may then be turned around a drum 2844 to press the granules into the asphalt coating and to temporarily invert the sheet so that the excess granules will fall off and will be recovered and reused. - In one embodiment, the
reinforcement material 35 may be attached to the shingle blank prior to the application of the asphalt coating, after the application of the asphalt coating, prior to application of granules, after application of granules, and at any of the locations illustrated byFIG. 28 . Further, therelease tape 50 may be applied at any of the locations and in the same manner as illustrated for the reinforcement material inFIG. 28 . - It will be understood, however, that in any of the embodiments described herein,
reinforcement material 35 may be applied as an extruded or liquid material, such as a polymer, that will adhere to themat 2812, the asphalt covered sheet 2818, the granule covered sheet 2840, and/or the lower surface of the asphalt coated sheet. - In another embodiment of the invention, a layer of material, such as talc or sand, may be applied to the first asphalt coated sheet 2818 shown in
FIG. 28 . The material may be applied by any desired means to a lower surface of the asphalt coated sheet 2818. Alternatively,granules 702 may be applied by any desired means to a lower surface of the asphalt coated sheet 2818 to make a thicker shingle blank. - In the
exemplary shingle 10 may have a nail pull-through value, measured in accordance with a desired standard, such as prescribed by ASTM test standard D3462. For example, theshingle 10 may have a nail pull-through value that is greater than in an otherwiseidentical shingle 10 having nosuch reinforcement 35. In one embodiment, theshingle 10 may have a nail pull-through value within the range of from about ten percent to about 100 percent greater than in an otherwise identical shingle having nosuch reinforcement material 35. In another embodiment, theshingle 10 may have a nail pull-through value about 50 percent greater than in an otherwise identical shingle having nosuch reinforcement material 35. - In another embodiment, a
shingle 10 having areinforcement material 35 formed from polyester film having a thickness of about 0.5 mils, may have a nail pull-through value about 13.3 percent greater than in an otherwise identical shingle having nosuch reinforcement material 35. In another embodiment, a shingle having areinforcement material 35 formed from polyester film having a thickness of about 3.0 mils, may have a nail pull-through value about 62.3 percent greater than in an otherwise identical shingle having nosuch material 35. In another embodiment, a shingle having areinforcement material 35 formed from polyester film having a thickness of about 4.0 mils, may have a nail pull-through value about 86.0 percent greater than in an otherwise identical shingle having nosuch reinforcement material 35. In another embodiment, a shingle having areinforcement tape 19 formed from polyester film having a thickness of about 5.0 mils, may have a nail pull-through value about 112.7 percent greater than in an otherwise identical shingle having nosuch tape 19. -
FIGS. 12-14 illustrate another exemplary embodiment of a laminated hip andridge shingle 10. Thelaminated shingle 10 includes abase layer 12 and adimensional layer 14. Referring toFIG. 13 , in an exemplary embodiment, thebottom surface 18 of thedimensional layer 14 is adhered to thetop surface 19 of thebase layer 12 by an adhesive 20. In the illustrated embodiment, the adhesive 20 extends only partially across the overlap between thebase layer 12 and thedimensional layer 14. The portion of thebase layer 12 that is not covered by thedimensional layer 14 is the portion of the shingle that will be exposed on the ridge of the roof. Thedimensional layer 14 will be completely covered by thebase layer 12 of the next shingle applied to theridge 118. Thedimensional layer 14 increases the thickness of the overlapping portions of twoshingles 10. This provides theridge 118 with a more dimensional appearance. - In the exemplary embodiment, the entire
dimensional layer 14 is on top of the base layer 12 (i.e. complete overlap). This complete overlap reduces the possibility that water can pass between thelayers shingle 10 can be bent over theridge 118 of the roof without tearing the top layer. - Referring to
FIG. 12 , an optional nailzone reinforcement material 35 is provided. The nailzone reinforcement material 35 can take a wide variety of different forms and can be applied to the laminated shingle at a wide variety positions.

In an exemplary embodiment, theadhesive line 40 extends in the direction of the width of the shingle, which may also be the machine direction (i.e. the direction in which the base layer travels through a production line as it is made. In another exemplary embodiment, the height of the shingle is the machine direction and theadhesive line 40 is applied in the cross-machine direction. In the illustrated embodiment, theadhesive line 40 is continuous. In other embodiments, theadhesive line 40 may be dashed. In an exemplary embodiment, theadhesive line 40 is positioned to adhere togranules 702 on thedimensional layer 14 between thereinforcement material 35 and anedge 704. In another embodiment, theadhesive line 40 is positioned to adhere to thereinforcement material 35. - Referring to
FIG. 14 , arelease tape 50 is provided on the back side of thebase layer 12. The laminated hip andridge shingles 10 are flipped over and turned 180 degrees when they are packaged, so that therelease tape 50 lines up with theadhesive line 40. Therelease tape 50 prevents the shingles from sticking together in the package. Therelease tape 50 can take a wide variety of different forms. - Referring to
FIGS. 15-17 , the hip andridge shingles 10 illustrated byFIG. 12-14 are constructed by cutting a single layer granule coatedsubstrate 16 or shingle blank into pieces to make thebase layer 12 and thedimensional layer 14. In the illustrated embodiment, the shingle blank 16 includes aheadlap region 428 and aprime region 430. Theheadlap region 428 of the shingle blank 426 is used to make thedimensional layer 14. Theprime region 430 of the shingle blank 426 is the portion of the hip or ridge roofing material that remains exposed when the hip andridge shingles 10 are installed. In one exemplary embodiment, the entire front surface of the shingle blank 426 is coated with prime roofing granules and the entire rear surface of the shingle blank 426 is covered with headlap granules. - Referring again to
FIGS. 15-17 , the shingle blank 16 may have any suitable dimensions. The shingle blank 426 may also be divided between theheadlap region 428 and theprime region 430 in any suitable proportion. For example, a typical residential roofing shingle blank 16 has a length L of approximately 36 inches (91.5 cm) and a height H of approximately 13¼ inches (30.5 cm) high, with the height H dimension being divided between theheadlap region 428 and theprime region 430. - In one exemplary embodiment, the shingle blank 16 has the same composition as the incorporated '994 patent to Miller et al. In another embodiment, the shingle blank can have other suitable compositions. The shingle blank 16 includes a substrate that is coated with an asphalt coating.
