Master Flow Pivot 4-in x 17-in Galvanized steel Vent and Pipe Flashing

The GAF Master Flow PivotTM Pipe Boot Flashing is a turning point in roof system protection. Designed and tested tough, the Pivot helps avoid leaks associated with many commodity plumbing pipe roof boots which can degrade and fail before the service life of the shingles. Help avoid headaches and protect your home against damaging leaks at one of the most vulnerable parts of your new or existing roof - penetrations (the place where plumbing pipes stick through your roof).
