Roof vent shield

Abstract

The roof vent shield is attached to the downslope side of an existing roof vent, to prevent the entrance of windblown moisture into the mouth of the vent. The shield includes an elongate panel disposed along the length of the vent, with the upper edges of the vent opening and panel forming a ventilation opening therebetween. The opposed ends of the panel include opposite vent attachment flanges, and the lower edge of the panel includes a roof attachment flange. The shield panel and its various attachment flanges may be formed of a single homogeneous sheet of material (galvanized steel, corrosion resistant steel, aluminum, etc.), or may be assembled from separate components at the time of manufacture. The shield panel is oriented at least generally normal to the plane of the roof when the device is installed, and may include reinforcing bends along its upper and lower edges for greater rigidity.
