ABSTRACT:
A unitary roof flange provides a weather-tight seal for horizontally arranged pipes entering a pitched, shingled roof. The flange is formed in one piece of plastic material and has substantially flat upper surfaces, so as to present surfaces which are substantially parallel to the roof surface to facilitate the flow of water thereover. The pipe enters the inventive flange at a surface which is downwardly facing in relation to the slope of the roof. A rubber grommet is provided at the interface between the horizontal pipe section and the roof flange to form a weather-tight seal.
