Residential Master Flash®

This unique flashing was designed for residential use with a built in 20 degree pitch allowing adaptability to almost any roof pitch including 45 degrees. The clearly marked designation of pipe diameter takes the guess work out of sizing. A “C20 ASTM” additional requirement was added to ensure conformance to the most stringent ozone/weathering specifications available. This addition allows the rubber a minimum 20 year life.
