How to Flash

Properly flashing penetrations in PVC, TPO and other membrane-type roofing requires the use of manufacturer-specific materials to ensure the flashing bonds chemically with the field membrane (ask your roofing supplier). For built up asphalt roofs (BUR) and other bituminous and modified bitumen roofs, aluminum flashings are available from Quick Mount PV in 4" and 8" tall cones (sold separately).
