  • Patent number: 6202372
    Abstract: A method and apparatus for providing ventilation to a building structure's roof is provided. The apparatus provides a low profile roof vent having improved resistance to bending and thus increased resistance to damage caused by the wind or other forces. Particularly, the apparatus provides a roof vent having generally I-beam shaped internal bracing in both vertical and horizontal directions. Thus, the apparatus of the present invention provides a roof vent that is highly resistant to failure due to exposure to strong winds. The present apparatus also offers improved air flow through the roof vent. The method of the present invention comprises providing a roof vent having a passageway that includes a front and a rear section. The rear section is in communication with a hole in the roof, while the front section is in communication with an exterior of the structure. A baffle between the hole and the exterior of the structure, along the surface of the roof, prevents water from entering the hole directly.
