Definitions
- This invention relates to roof vents, and more specifically to passive attic vents for use on tile roofs.
- a passive attic vent with a camouflaged appearance has been marketed in recent years. This camouflaged vent has been difficult to manufacture and install. What is needed is an improved passive ventilation system that will not affect the appearance of a building design if used in adequate numbers to properly ventilate the attic, and is useable on many roof configurations and with many types of roofing material.
- the present invention provides a ventilation system for an attic or rafter space that mimics the appearance of roofing tiles and thus has a rnimmal negative effect on the appearance of the building.
- the vent has two pieces, a primary vent, and a secondary vent and they may be made of aluminum, steel or copper.
- the primary vent is installed on a roof deck with a primary vent opening over a ventilation opening cut through the deck.
- the secondary vent is constructed to look like the surrounding field tiles and is installed over the primary vent.
- the secondary vent has a skeleton with one or more vent openings and a cap covering each opening creating a ventilating access.
- the one or more vent openings in the secondary vent and the opening in the primary vent conduct air between the attic or rafter space arid the outside.
- the present invention provides a roof vent for mounting between field tiles on a pitched, tile roof
- the roof vent includes a primary vent for mounting on the roof in ventilating communication with an opening there through, a roof tile-shaped vent skeleton having an upslope edge and a parallel downslope edge and a pitch axis perpendicular to the upslope and the downslope edges
- the vent skeleton is formed of a single continuous piece of material and includes one or more vent openings
- the vent skeleton is mounted on the roof above the primary vent with the pitch axis of the vent skeleton parallel to the roof pitch with the vent openings in ventilating communication with the roof opening, and a vent cap attached to the vent skeleton adjacent each of the one or more vent openings creating a ventilating access between the vent cap and the skeleton.
- the present invention provides a roof vent wherein the upslope and downslope edges precisely fit against adjacent upslope and downslope field tiles respectively, and the vent skeleton has a cap flange to precisely fit under and against the cap of an adjacent field tile, and the vent skeleton also has a pan flange to precisely fit against a pan of an adjacent field tile.
- the present invention provides a vent skeleton having a plurality of ribs perpendicular to the pitch axis.
- Fig. 1 is a perspective view of a secondary vent skeleton and caps, according to the present invention, installed on a portion of a roof.
- Fig. 2 is a top view of a secondary vent skeleton and caps according to the present invention.
- Fig. 3 is a bottom view of the secondary vent skeleton and caps of Fig. 2.
- Fig. 4 is a cross-section view of the secondary vent skeleton and caps of Fig. 2 taken along 4-4.
- Fig. 5 is a cross-section view of the secondary vent skeleton and caps of Fig. 2 taken along 5-5.
- Fig. 6 is a cross-section view of the secondary vent skeleton and caps of Fig. 2 taken along 6-6.
- Fig. 7 is a perspective view from below of the front cap corner of a secondary vent skeleton and cap according to the present invention.
- Fig. 8 is a perspective view of a mounting location for a primary vent showing the hole marked on the roof.
- Fig. 9 is a perspective view of a mounting location for a primary vent showing the hole being cut in the roof.
- Fig. 10 is a perspective view of a mounting location for a primary vent showing the primary vent being prepared for installation.
- Fig. 11 is a perspective view of an installed primary vent showing the relationship to a secondary vent according to the present invention.
- a section of pitched roof 11 near eave 60 is shown including a roof vent 10 according to a preferred embodiment of the present invention.
- Pitched roof 11 is generally composed of a plurality of field tiles 21, surrounded by edge tiles 13, edge caps 15 and ridge caps (not shown).
- Roof vent 10 is in two parts, primary vent 40 (shown in Fig. 11) and secondary vent 12.
- Roof vent 10 may be formed from any suitable metal such as aluminum, steel, or copper. In a currently preferred embodiment of the present invention roof vent 10 is formed of 26 gauge galvanized steel.
- secondary vent 12 includes one or more caps 14 attached to lower piece or skeleton 16. Secondary vent 12 serves as a replacement for one or more field tiles 21 on pitched roof 11. Different tile types and similar looking tiles from different manufacturers have different physical dimensions and may require a unique skeleton configuration for a precise fit between the tiles and skeleton 16. Specific fit may be required between, upslope edge 42 to upslope tile 21U, pan flange 24 to pan 25, downslope edge 45 to downslope tile 13D and cap flange 22 to cap 23. Skeleton 16 may be made to fit the contours and edge configuration of the field tiles 21 used. Skeleton 16 may be formed in any conventional manner.
- Skeleton 16 is stamped from a single piece of material to fit precisely the field tiles 21 for which it is intended to be used.
- Skeleton 16 includes one or more pan areas 18 and a cap area 20 adjacent each pan area 18.
- pan areas 18 are concave and cap areas 20 are convex.
- Pan areas 18 align with individual pan tiles or with corresponding pan areas of field tiles such as pan areas 17 of Fig. 1.
- Cap areas 20 align with individual cap tiles or with corresponding cap areas of field tiles 21 such as cap areas 19 of Fig. 1.
- Secondary vent 12 is mounted with pitch axis 31 parallel to the pitch of pitched roof 11.
- Cap flange 22 is configured to fit underneath the cap of an adjacent field tile such as cap 23 as shown in Fig. 1.
- Cap flange 22 may include one or more creases such as crease 30 to obtain a precise fit to an adjacent field tile.
- Cap flange 22 may also have one or more bevels such as bevel 32 to minimize interference with an adjacent field tile.
- Pan flange 24 is configured to mate with the pan of an adjacent field tile such as pan 25 as shown in Fig. 1.
- Pan flange 24 may include one or more creases such as crease 28 to obtain a precise fit to an adjacent field tile.
- a plurality of ribs 26, 26A and 26B are stamped into skeleton 16 for increased rigidity.
- ribs 26, 26 A and 26B are parallel to upslope edge 42.
- a hole 34 is included in each pan area 18 to accept a conventional fastener, such as a nail or a screw, to secure secondary vent 12 to a roof such as pitched roof 11.
- a conventional fastener such as a nail or a screw
- Skeleton 16 includes a vent opening 36 in each cap area 20. When installed above primary vent 40 as shown in Fig. 11, vent openings 36 are in ventilating communication with vent opening 46. Each vent opening 36 is located between ribs 26A and 26B. A turtle 38 is attached to each pan area 18 adjacent edge 40. Turtle 38 is a spacer that compensates for the difference in thickness between field tiles 21 and skeleton 16. Turtle 38 may be formed and attached in any conventional manner to raise skeleton 16 above the roof battens such as batten 70 (in Fig. 11). Thickness compensating fingers 43 are formed along the downslope edge 45 of cap area 20.
- Thickness compensating fingers 43 compensate for the difference in thickness between field tiles 21 and skeleton 16 to provide a seal against the top of a downslope field tile such as downslope tile 13D.
- Wind clips 44 are attached to skeleton 16 to secure secondary vent 12 to lower course tiles 45 shown in Fig. 11.
- Ribs 26, 26A, 26B, 50 and turtle 38 are seen in profile.
- Ribs 26 are shown concave up however other configurations may be suitable.
- Rib 26B is shown convex up however other configurations may be suitable.
- Rib 26A must be oriented concave up to minimize interference with caps 14 at shoulder 48.
- Ribs 50 are shown concave down however other configurations may be suitable.
- Legs 52 are attached to skeleton 16 and to caps 14 to support caps 14 and maintain ventilating access 54 between skeleton 16 and caps 14. Legs 52 may be attached in any conventional manner.
- Caps 14 shield vent openings 36 from the weather and are attached to cap area 20 by any conventional means.
- a cap 14 is spot welded at shoulder 48 and legs 52.
- Caps 14 include side hems 27, a front hem 29, and ribs 50.
- ribs 50 extend from one side hem 27 to the other parallel to front hem 29.
- Side hems 27 and front hem 29 are included to improve the weather shielding efficiency of cap 14 without sacrificing ventilating efficiency.
- Ribs 50 and are stamped into caps 14 for rigidity. Front and side hems 29 and 27 may be made in any conventional manner such as cutting and bending.
- front and side hems 29 and 27 are formed by stamping to increase the rigidity of caps 14, and caps 14 are made in one standard size.
- a standard size cap 14 may be fitted to many different skeletons thus minimizing manufacturing and inventory complexity.
- Vent 10 serves dual purposes, ventilating attic 64 and protecting attic 64 from weather and pests.
- Vent opening 36, vent opening 46 and attic opening 58 cooperate to conduct attic air 62 from attic 64.
- Caps 14 are attached to skeleton 16 as shields over vent opening 36 to prevent weather and pests from falling directly into attic 64. Caps 14 also prevent direct solar irradiation of attic 64.
- Vent openings 36 are covered by screen 37 to prevent entry into space 66 by pests larger than the screen openings.
- Baffles 55 shield vent openings 36 from wind driven moisture and particles, and extend along edges R and L.
- Baffles 55 are H high and they are folded up along angle A between 0 and 90 from vent opemng 36.
- H is .25" and angle A is 50 .
- Cap 14 includes side hems 27, and a front hem 29 (shown in Fig. 7) to further shield vent opening 36 from entry of foreign matter. Side hems 27, and front hem 29 extend from cap 14 to below vent opening 36.
- Attic air 62 flowing through a passive vent such as vent 10 follows the same path whether from outside 65 into attic 64, or from within the attic 64 to outside 65, only the direction of flow changes.
- attic air 62 flow from attic 64 to outside 65 will now be described with the understanding that the present invention functions equally well conducting air in both directions. Air travelling through vent 10 must undergo a change of direction that helps to prevent foreign matter from entering attic 64.
- vent opening 46 of primary vent 40 provides a convection driven ventilating channel through roof deck 56. Primary vent 40 conducts air up from within attic 64 through attic opening 58 and vent opening 46 to space 66. Convection continues to drive attic air 62 up through vent opening 36 into ventilating access 54.
- Attic air 62 in ventilating access 54 is then conducted up over baffles 55. Once above baffles 55 the shape of vent cap 14 and hems 27 and 29 cause attic air 62 to change direction and travel down beyond side hems 27 or front hem 29 to outside 65.
- Thickness compensating fingers 43 may be formed by any conventional means, in a currently preferred embodiment of the present invention, thickness compensating fingers 43 are cut into downslope edge 45 of cap area 20 and folded. Due to the thickness disparity between skeleton 16 and adjacent field tiles 21, thickness compensating fingers 43 are needed to provide a pest seal against the top of the down slope field tile 21 when pan flange 24 is fitted to the pan of an adjacent field tile such as pan 25 as shown in Fig. 1.
- FIG. 8-11 installation steps for roof vent 10 are illustrated.
- location 57 on roof deck 56 is selected for installation of roof vent 10.
- Location 57 is marked to delineate where attic opening 58 will be cut.
- saw 59 is used to cut attic opening 58 through roof deck 56.
- sealant 61 is applied to bottom side 41 of primary vent 40.
- Primary vent 40 is installed with bottom side 41 in contact with roof deck 56 and vent opening 46 in ventilating communication with attic opening 58.
- secondary vent 12 is then installed above primary vent 40 with vent openings 36 in ventilation communication with vent opening 46.
- Vent opening 46 may be provided with screen 46S for additional protection against introduction of vermin or debris through attic opening 58.
- roof vents 10 should be used in pairs. A pair of roof vents 10 are located on a roof parallel to the rafters with a first roof vent 10 near the roof peak (not shown) and a second roof vent 10 near eave 60. This configuration promotes passive air convection through the attic or rafter space as warm air rises through the first roof vent 10 cooler air is drawn into the attic or rafter space through second roof vent 10.
