ABSTRACT:
A roof ventilator (10) comprises a contoured, substantially rounded cover member (12) including a nailing tab and flange configuration to allow use of the ventilator on roofs and roof ridges of different angles and pitches. A vent (14) is located in the cover member (12), and the vent has openings (16) to permit air circulation through the roof or roof ridge, and includes weepage openings (24) at the bottom of the vent to permit any collected liquids to drain therethrough. The shape of the vent is designed to deflect air flow over the roof ventilator, thereby substantially preventing foreign particle entry through the roof ventilator into the building.
