Weather Watch® Granular Surfaced Leak Barrier from GAF
StormGuard® Film-Surfaced Leak Barrier provides superior performance for both asphalt shingle roofs and metal roofs. Used at the most vulnerable areas of a roof (eaves, rakes, in valleys, around chimneys), it creates a 100 percent watertight seal. The unique film surface pattern helps improve footing, even in hot weather, for safer installation. It also benefits from the same warranty length as the asphalt shingles it is applied under, up to 30 years. For metal roofing applications, StormGuard®HT Leak Barrier is designed to withstand high metal roof temperatures, and can even be left exposed for up to 60 days, if required!
