Quick Mount's Low Slope Mount takes the traditional base-and-post PV mount to its ultimate level. It's the strongest you can buy for mechanically attaching commercial PV systems to TPO, PVC, EPDM, built-up asphalt, and virtually all other non-metal low slope roofs.


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).
