ABSTRACT:
An improved device for forming a weather-tight seal to a vent pipe and over a roof flashing. The device utilizes a high durability elastomeric material with a truncated conical shape and thickened upper lip to form a rain shed over the roof flashing, thereby ensuring a tight, durable seal to the vent pipe that prevents intrusion of moisture between the vent pipe and roof flashing.
