      By creating a barrier at the most vulnerable areas of your shingle or metal roof (at the eaves and rakes, in valleys, around chimneys, etc.), StormGuard® Film-Surfaced Leak Barrier will help 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 System2 and has earned the Good Housekeeping Seal5 (U.S. only).  It is eligible for a Lifetime limited warranty when used on Lifetime Shingle roofs,2 a 25-year ltd. warranty when used on non-Lifetime Shingle roofs,2 and a 10-year ltd. warranty3 when used with other approved non-asphaltic roofing systems.1

      High-temperature compound designed for use with asphalt shingle and most metal roof systems1
      • 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”. Also, in some jurisdictions, full-deck coverage of leak barrier is required.4

      • Great Look:  Fiberglass reinforcement helps resist wrinkling and buckling.
      • Dependable:  Self-seals around nails or metal roofing fasteners to help avoid leaks.
      • Saves Labor:  Split-back release film peels off in layers for fast installation.
      • Convenient:  2.0 square (200 ft.2 [18.58 m2]) roll size.
      • Versatile:  High-temperature compound is perfect for use under asphalt shingles and most metal roofing systems.1
      1The high-temperature compound is suitable for most metal roofing system applications.  For use under copper and zinc or for information on other approved non-asphaltic roofing systems, contact GAF Technical Services at 1-800-ROOF-411.
