There's no need for trimming shingles to force a fit. Drill one pilot hole into the rafter, backfill it with appropriate sealant, slide the Quick Mount flashing beneath the felt in the course above, drive the bolt home, and it's done.
The 12 x 12-inch Classic Composition Mount flashing is designed to fit within a standard 5 to 5.5" course and the exposed course should be no greater than 5.75". If the exposure is greater than this, use the Shake Mount as an alternative. There's no shingle cutting and no shingle distortion caused by trying to force a fit. Just a permanent, watertight mount every time!
PV, Solar Hot Water, and More The Quick Mount PV Classic Composition Mount is the logical choice not only for solar PV installation, but also for rooftop solar hot water systems. In fact, whatever you need to fasten to a composition roof – HVAC equipment, antennas, satellite dishes – use Quick Mount PV to secure and protect every roof installation you put your name on.
