Roof Flow

The GAF Master Flow™ Pivot™ Pipe Boot Flashing helps protect roofs against damaging leaks at plumbing pipe penetrations, one of the most vulnerable areas of a roof.  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 callbacks.  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 four impact resistance test, and is now available in both three inch and four inch sizes.  This follows the launch of the 1.5” and 2” models that were launched in spring 2023.

         A turning point in roof system protection, the Master Flow Pivot Pipe Boot Flashing provides an ease of installation with features such as pre-punched nail fastening guides, universal pitch adjustment, directional installation arrows, and shingle termination guides.

         Also featuring a ball and socket component for simple rooftop pitch adjustment, the Master Flow Pivot Pipe Boot Flashing is available in four colors for a streamlined look on the roof.  It is warrantied against leaks caused by manufacturing defects or ordinary wear and tear for the length of the warranty on the adjacent roof cladding, not to exceed 50 years, and is eligible for enhanced warranty coverage when installed by a contractor certified by GAF in connection with a qualifying roofing system.
