S-shaped roof vent, ventilated roof employing the same and method of installing the same

Abstract

A generally S-shaped vent is provided for a roof including a substructure having at least one ventilation hole and being covered by a plurality of tiles. The tiles form a finish layer having peaks and valleys. The vent includes a base assembly having a number of flange members and at least one venting member with a vent aperture. The flange members are coupled to the roof substructure at or about the ventilation hole. At least one cap member is coupled to the base assembly, overlaying the vent aperture and including an upslope end, a downslope end, first and second sides, and an arcuate portion extending between the first and second sides. First and second louvered portions of the first and second sides of the cap member provide a ventilating passageway through the vent. The vent substantially conforms to the peaks and valleys of the finish layer of the roof.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates generally to vents and, more particularly, to generally S-shaped roof vents for ventilating the roof of a structure, such as a building, while conforming to the general shape of the finish layer of the roof. The invention also relates to ventilated roofs. The invention further relates to a method of installing roof vents.[0003]2. Background Information[0004]Vents are commonly employed on the roofs of structures, such as residential buildings, commercial buildings and other structures, in order to exhaust air from beneath the roof (e.g., from an attic space) into the surrounding atmosphere.[0005]For example, a variety of passive roof vents have been employed at various locations on building roofs in an attempt to release heat which can undesirably build up and become trapped under the roof. Passive vents provide an air passageway for such hot air to be exhausted from the roof, and thereby help to ma...

AI Technical Summary

Benefits of technology

[0026]It is another object of the invention to provide an improved method of installing generally S-shaped roof vents wherein the sub-flashing of the vent can be installed prior to cutting the ventilation hole in the roof, and wherein the sub-flashing can serve as a template to optimize the precision with which such ventilation hole is made.

Problems solved by technology

Such vents also serve a safety function, as excessive heat can result in damage to the roof, and could potentially cause a fire.

This can be particularly difficult where, for example, the tiles of the roof have a relatively complex shape such as, for example, the general S-shape which is commonly associated with Spanish tiles.

This disadvantageously requires numerous different skeletons to be made for each particular type of roof application.

Such spacing presents the possibility for debris, animals, moisture, or other matter to undesirably enter under the vent cap, through the space between the cap and the base.

In addition to the foregoing, there are also a number of unique problems with the manner in which such vents must be installed.

Such problems are, in large part, related to the construction of the vents.

However, the roof might not be tiled until several days or even weeks later.

Accordingly, the aforementioned matter, such as moisture, and relatively small debris can undesirably enter the building through the primary vent.

It is also difficult to size and position the hole in the roof decking precisely so as to match the hole of the primary vent in order to maximize the net flow area and ventilation through the vent.
