Abstract

A roof deck intake vent is provided. The roof deck intake vent includes a first portion connected to a second portion. The first portion is further connected to an upper edge and the second portion further connected to a lower edge. Opposing first and second side walls are connected to the first and second portions. The opposing first and second side walls extend from the upper edge to the lower edge. The first and second side walls form an extension having a lower surface. The first portion, upper edge, and the extension cooperate to form an air intake, such that air entering the roof deck intake vent enters the vent through the lower surface of the extension when the vent is installed on an edge or eave of a roof.

First claim

What is claimed is:

1. A roof deck intake vent comprising:
a first top wall connected to a second top wall, the first top wall extending from a lower edge to the second top wall, and the second top wall extending from the first top wall to an upper edge;
opposing first and second side walls connected to the first and second top walls, the opposing first and second side walls extending from the upper edge to the lower edge, and from the first and second top walls, the first and second walls each including a main portion extending from the upper edge to an extension portion, the extension portion extending from the main portion to the lower edge;
wherein at least a portion of each extension portion extends below a bottom edge of each main portion when the bottom edge is oriented horizontally.

2. The roof deck intake vent of claim 1 , wherein in an installed position on a roof deck, the extension portions are positioned such as to prevent wind driven rain from entering the roof deck intake vent.

3. The roof deck intake vent of claim 1 , wherein the second top wall forms an angle with the bottom edge of the main portion of the first side wall ranging from about 5° to about 30°.

4. The roof deck intake vent of claim 1 , wherein the first top wall has a length ranging from about 4.0 inches to about 9.0 inches and the second top wall has a length ranging from about 3.0 inches to about 14.0 inches.

5. The roof deck intake vent of claim 1 , wherein a spoiler extends from the first top wall.

6. The roof deck intake vent of claim 5 , wherein the spoiler is configured to assist in the flow of air over shingles installed on top of the roof deck intake vent to thereby reduce uplift forces that act on the shingles due to wind.

7. The roof deck intake vent of claim 1 , wherein the first and second top walls have top surfaces that are textured.

8. The roof deck intake vent of claim 1 , wherein the first top wall includes a plurality of louvers.

9. The roof deck intake vent of claim 8 , wherein the louvers are covered by shingles when the roof deck intake vent is in an installed position.

10. The roof deck intake vent of claim 1 , wherein the first top wall forms an angle with the lower edge ranging from about 115° to about 130°.

11. The roof deck intake vent of claim 10 , wherein the lower edge is substantially vertical when the roof deck intake vent is in an installed position.

12. The roof deck intake vent of claim 1 , further comprising lower edge baffles, intermediate baffles, and nailing baffles.

13. The roof deck intake vent of claim 1 , wherein bottom edges of the extension portions are substantially parallel to the first top wall.

14. The roof deck intake vent of claim 1 , wherein an air intake is formed by the extension portions of the first and second side walls and the lower edge, the air intake having an unobstructed area ranging from about 7.0 square inches per lineal foot to about 20.0 square inches per lineal foot.

15. The roof deck intake vent of claim 5 , wherein the spoiler forms an angle with the lower edge ranging from about 120° to about 160°.

16. The roof deck intake vent of claim 1 , wherein at least a portion of the lower edge extends below a plane defined by an outer surface of a roof deck when the roof deck intake vent is in an installed position.

17. The roof deck intake vent of claim 1 , wherein an air intake is spaced apart from the first top wall by the lower edge.

18. The roof deck intake vent of claim 1 , wherein the lower edge is configured as a barrier to the flow of air into the roof deck intake vent.

19. The roof deck intake vent of claim 1 , wherein a bottom of the roof deck intake vent is completely open.

20. The roof deck intake vent of claim 19 , wherein an air intake is formed by projections that extend downward from the first top wall of the roof deck intake vent.

21. The roof deck intake vent of claim 1 , wherein the first top wall is connected to the second top wall by an intermediate top wall.

22. The roof deck intake vent of claim 1 , wherein the first top wall is connected to the second top wall by an intermediate top wall, and lengths of the first top wall and the intermediate top wall correspond to an exposed portion of an overlying shingle.

23. The roof deck intake vent of claim 1 , wherein the first top wall is connected to the second top wall by an intermediate top wall, and lengths of the first top wall and the intermediate top wall correspond to a tab portion of an overlying shingle.

24. The roof deck intake vent of claim 1 , further comprising a shiplap projection and a shiplap recess that allow two adjacent roof deck intakes to be installed in a ship-lapped configuration.

25. The roof deck intake vent of claim 1 , further comprising a top air intake formed in the top wall of the roof deck intake vent.

26. The roof deck intake vent of claim 25 , wherein the top air intake includes a mesh.

27. The roof deck intake vent of claim 1 , wherein a front edge of the lower edge is lower than a remainder of the roof deck intake vent when the roof deck intake vent is installed on an edge of a roof.

28. The rook deck intake vent of claim 1 , wherein the roof deck intake vent is positioned on a roof deck that extends to an eave, wherein the lower edge of the roof deck intake vent is spaced apart a distance from the eave.

29. A roof comprising:
an eave;
a roof deck extending to the eave;
a plurality of shingles arranged on the roof deck; and
a roof deck intake vent disposed on the roof deck, the roof deck intake vent comprising:
a first top wall connected to a second top wall, the first top wall extending from a lower edge to the second top wall, and the second top wall extending from the first top wall to an upper edge;
opposing first and second side walls connected to the first and second top walls, the opposing first and second side walls extending from the upper edge to the lower edge, and from the first and second top walls, the first and second walls each including a main portion extending from the upper edge to an extension portion, the extension portion extending from the main portion to the lower edge;
wherein at least a portion of each extension portion extends below a bottom edge of the main portion when the bottom edge is oriented horizontally;

wherein the extension portions are disposed beyond the eave of the roof and extending below a plane defined by an outer surface of the roof deck.

30. A roof comprising:
an eave;
a roof deck extending to the eave;
a plurality of shingles arranged on the roof deck; and
a roof deck intake vent disposed on the roof deck, the roof deck intake vent comprising:
a first top wall connected to a second top wall, the first top wall extending from a lower edge to the second top wall, and the second top wall extending from the first top wall to the upper edge;
opposing first and second side walls connected to the first and second top walls, the opposing first and second side walls extending from the upper edge to the lower edge, and from the first and second top walls, the first and second walls each including a main portion extending from the upper edge to an extension portion, the extension portion extending from the main portion to the lower edge;
wherein at least a portion of each extension portion extends below a bottom edge of the mai
