      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.2 It is eligible for a Lifetime limited warranty when used on Lifetime Shingle roofs,2 and it's an eligible component of GAF residential enhanced warranties. It is also covered by a 10-year limited warranty3 when used with other approved non-asphaltic roof coverings.

      • Code Compliance and Risk Reduction:  Protection against ice dams is required by most building codes4 at eaves wherever the January average temperature is 25°F (-4°C) or lower or where there is a possibility of ice forming in the eaves — i.e., the area labeled “North”.  In Southern/warmer climates, leak barriers provide critical protection against wind-driven rain.

      • Strong Protection:  Guards vulnerable areas of your roofi including eaves and rakes, in valleys, around chimneys and skylights, and more.
      • Dependable:  Self-seals around nails or metal roofing fasteners to help avoid leaks.

      2Lifetime refers to the length of warranty coverage provided and means as long as the original individual owner(s) of a single-family detached residence [or the eligible second owner(s)] owns the property where the qualifying GAF products are installed.  For other owners/structures, Lifetime coverage is not applicable.  Lifetime coverage on shingles requires the use of GAF Lifetime Shingles only.  Lifetime coverage on shingles and accessories requires the use of any GAF Lifetime Shingle and any 3 qualifying GAF Accessories.  See GAF Roofing System Limited Warranty for complete coverage and restrictions.  Visit gaf.com/LRS for qualifying GAF products For installations not eligible for the GAF Roofing System Limited Warranty, see the GAF Shingle & Accessory Limited Warranty.
