Abstract
A roof vent comprising a one-piece plastic body including a base wall with air guiding vanes to ventilate the interior of a building. A plurality of spaced intermediate transverse supports are provided along the central longitudinal axis of the plastic body. The intermediate supports are adapted to facilitate folding at the center of the vent to maintain a straight line bend and to provide support for the central portion of the vent to improve stiffness and appearance. The supports overlap to accommodate different roof angles. Additionally, the roof vent has a tongue and groove arrangement on the end walls at each end for an interlocking connection to an adjacent roof vent. One embodiment of the roof vent is adapted for use on a hip roof. In this embodiment, a separate wall is used to deflect entry of snow or rain. The supports have notches to accommodate the separate wall. Furthermore, drain openings are provided in the vanes and the end walls to allow moisture to escape and cross-walls are also provided to prevent moisture from flowing along the inside surface of the roof vent.
