The GAF Master Flow Pivot Pipe Boot Flashing helps protect your roof against damaging leaks at one of the most vulnerable areas — plumbing pipe penetrations. The all-metal construction fully encapsulates unsightly plumbing pipes with no exposed gaskets, seals, collars, or caulk that can degrade over time, causing leaks and homeowner call-backs.
The new Master Flow Pivot Pipe Boot Flashing is designed and tested to pass the 110 mph wind-driven rain test per TAS-100(A) and UL 2218 Class 4 impact resistance test,* and is now available in both 3-inch and 4-inch sizes. This follows the launch of the 1.5-inch and 2-inch models that were launched in spring 2023.
