GAF STORMGUARD 0925000MV Film-Surfaced Leak Barrier, 66.7 ft L, 36 in W, Asphalt/Fiberglass Mat

Self-sealing protection for vulnerable areas of the roof against wind driven rain and ice dams. By creating a barrier at the most vulnerable areas of your asphalt shingle or metal roof (at the eaves and rakes, in valleys, around chimneys, etc) StormGuard® film surfaced leak barrier helps prevent leaks due to water backing up in your gutters, wind driven rain and in the North, damaging ice dams. It will also help protect your home from expensive wall and ceiling staining from leaks. StormGuard® film surfaced leak barrier is a key part of the GAF lifetime roofing system. It is eligible for a lifetime limited warranty when used on lifetime shingle roofs and it's an eligible component of GAF residential enhanced warranties. It is also covered by a 10 years limited warranty when used with other approved non-asphaltic roof coverings.
