Master Flash® Res Aluminium

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.

Check diameter of your pipe or duct and select appropriate Residential Master Flash® to accommodate your application as indicated on the chart below. For extreme pitch or surface irregularity, select next larger size.
