Low profile roof vent
A roof vent has a body with a flange removably mountable adjacent a roof surface and a base attached to a distal end of the flange and disposed between two side walls, where the base and the side walls define a compartment therebetween. The compartment is disposed in an area beneath the roof surface when the flange is mounted to the roof surface, wherein the base extends at an angle relative to the flange to direct water that enters the compartment toward the distal end of the flange and onto the roof surface. An opening in the body allows airflow between the compartment and the area beneath the roof surface outside the body. A cover is removably mountable over the flange so that the roof vent has a low profile relative to the roof surface. The cover has a surface and at least one opening configured to substantially allow airflow between the compartment and an area above the roof surface.
1. Field of the Invention
The present embodiments generally relate to roof vents, and more particularly to a roof vent that minimizes the ingress of water into a building while allowing airflow through the roof.
2. Description of the Related Art
Roof vents are employed as integral parts of a useful roof design. Roof vents are most often used for keeping the attic space of a building cooler and allowing “hothouse” gases to escape.
To do this, the vent provides a passage for air to flow out of a house, building, warehouse, attic or otherwise unventilated room or area to the outside and vice-versa. However, a desirable roof vent must also inhibit the entry of liquid, particulate matter, and vermin, such as rain and rodents, into the ventilated room. Additionally, a low-profile roof vent that fits discretely onto an angled roof is also desirable. Accordingly, a need exists for an improved roof vent providing adequate airflow into and out of a building, while preventing the ingress of water, particulate matter, and vermin into the building, and while fitting discretely onto a roof surface.
SUMMARY OF THE INVENTIONIn accordance with one disclosed embodiment, a roof vent is provided comprising a flange extending between a proximal end and a distal end, where the flange is removably mountable adjacent a roof surface. The roof vent also comprises a base attached to the distal end of the flange and disposed between two side walls, where the base and the side walls define a compartment between them. The compartment is disposed in an area beneath the roof surface when the flange is mounted to the roof surface, wherein the base extends at an angle relative to the flange to direct water that enters the compartment toward the distal end of the flange and onto the roof surface. The roof vent also comprises a cover that is removably mountable over the flange. The cover has at least one opening configured to substantially allow airflow between the compartment and an area above the roof surface.
In accordance with another disclosed embodiment, a roof vent comprises a body removably mountable to a roof surface so that a substantial portion of the body is disposed in an area beneath the roof surface. The body defines a channel therein and has a base extending generally at an angle relative to the roof surface. The body also has an opening that substantially allows airflow between the channel and an area beneath the roof surface outside the body. The base is configured to substantially prevent the flow of water into the area beneath the roof surface outside the body.
In accordance with yet another embodiment, a roof vent is provided comprising a body removably mountable to a roof surface so that a substantial portion of the body is disposed in an area beneath the roof surface. The body has a base extending generally at an angle relative to the roof surface to direct a fluid that enters the body onto the roof surface. The roof vent also comprises a cover removably attached to the body and defining a drain between the cover and the body. The cover defines at least one opening therein and is oriented generally parallel to the roof surface. The roof vent also comprises means for substantially allowing airflow between an area beneath the roof surface outside the body and an area above the roof surface.
In accordance with yet another embodiment, a method for venting a roof is provided, comprising cutting an opening of a desired size in a roof surface. The method also comprises providing a roof vent comprising a body that defines a channel and has a flange and a base angled relative to the flange. The method further comprises attaching the roof vent to the roof surface so that the flange is adjacent the roof surface and the channel is in communication with the opening, where a substantial portion of the body is disposed in an area beneath the roof surface. The method additionally comprises positioning a vent cover over the flange, wherein the cover and the flange define a drain therebetween, and fastening the vent cover to the flange or the roof surface.

As discussed above and shown in
The cover 20 preferably has a surface 20a that defines at least one opening 22 therein. In the illustrated embodiment, the cover 20 has two openings 22. However, the cover 20 can have any suitable number of openings. In one embodiment, the opening 22 can extend substantially the entire length and width of the cover 20. In another embodiment, the opening 22 can extend over a portion of the length or width of the cover 20.
Preferably, the cover 20 is filtered to substantially allow airflow through the cover 20, but substantially prevent the passage of larger matter therethrough. In the illustrated embodiment, the cover 20 is louvered and has multiple fins 24 positioned across the openings 22. In one embodiment, the fins 24 are angled relative to the surface 20a. However, other suitable configurations can be used to provide a filtered cover 20. In one embodiment (not shown), a wire mesh screen can be disposed over the openings 22. In another embodiment (not shown), the openings can be sufficiently small to allow airflow through the cover 20, but substantially prevent the passage of larger matter therethrough.

As shown in
The body 10 and cover 20 of the roof vent 100 are preferably made of metal. In one embodiment, the body 10 and cover 20 can be made of sheet metal such as stainless steel. However, the roof vent 100 can be made of any suitable materials for roof vents that can withstand corrosion from water or damage from windblown objects. In one embodiment, the flange 12, side walls 14a, 14b, and base 16 are separate components fastened to each other via, for example, brackets, welds, screws, or other suitable fasteners. In another embodiment, the flange 12, side walls 14a, 14b and base 16 are formed from a unitary sheet of metal via a suitable process, such as stamping using a punch-press.
The method also includes providing 62 a roof vent 100 comprising a body 10 that defines a channel 18, a flange 12, and a base 16 angled relative to the flange, as described in the embodiments above.
The roof vent 100 is preferably attached 64 to the roof surface R so that the flange 12 is on top of the roof surface R and the channel 18 communicates with the opening 200 (See
The method also comprises positioning 66 the vent cover 20 over the flange 12, wherein the cover 20 and flange 12 define the drain 28 therebetween, as discussed above. The vent cover 20 is preferably fastened 68 to the flange 12, as discussed above. In one embodiment, the vent cover 20 is also fastened to the roof surface R with the flange 12 interposed therebetween.
In another embodiment (not shown), the roof vent 100 is attached to the roof surface R so that the flange 12 is positioned adjacent an underside of the roof surface R and fastened thereto. In this embodiment, the cover 20 can be positioned on top of the roof surface R over the opening 200 and secured to the roof surface R, so that the drain 28 communicates with the opening 200. Optionally, the cover 20 can also be secured to the flange 12. In still another embodiment (not shown), the roof vent 100 is installed so that the vent cover 20 is secured to an underside of the roof surface R about the opening 200, and the flange 12 is then secured to the vent cover 20.
In any of the embodiments discussed above, the junction between the flange 12 and the roof surface R is preferably sealed to substantially prevent water from entering through said junction into the area beneath the roof surface R. In one embodiment, the junction can be sealed using sealing glue or other similar adhesive. In another embodiment, a seal strip can be disposed between the flange 12 and the roof surface R. One of ordinary skill in the art will recognize that other suitable mechanisms can be used to seal the junction between the flange 12 and the roof surface R.
As shown in
The roof vent 100 also advantageously substantially prevents the ingress of large matter through the roof vent 100 into the area below the roof surface R. For example, the filtered openings 22 of the cover 20 substantially prevent leaves, rodents, and the like from entering the compartment 18 of the body. Additionally, the grill 30 further substantially prevents the ingress of such large matter from the compartment 18 into the area below the roof surface R outside the body 10. Further, as discussed above, the drain 28 is sized to allow the drainage of water from the compartment 18 but to substantially prevent the ingress of large matter therethrough into the compartment.
Still another advantage of the roof vent 100 is that it efficiently drains a fluid F, such as water, that enters the roof vent 100 while substantially preventing said fluid F from entering the area below the roof surface R outside the body 10. When the flange 12 is fastened to the roof surface R, the base 16, which is angled relative to the flange 12, is inclined relative to the roof surface R, as shown in
Yet another advantage of the roof vent 100 is that is has a low profile when installed on the roof surface R, as shown in
