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’s eligible for Lifetime ltd. warranty when used on Lifetime Shingle roofs² and it’s an eligible component of GAF residential enhanced warranties.  It’s also covered by up to a 10-year ltd. 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 roof including eaves and rakes, in valleys, around chimneys and skylights, and more
• Blue Synthetic Surface:  Durable, patterned film surface provides excellent wet/dry traction for installers and is perfect for full-deck application
• Integral Surface Channels:  Helps move moisture away from the walking surface
• Cooler to Work on:   The blue surface is cooler to work on (vs. typical black underlayments)
• Versatile:  250^oF high-temperature compound is perfect for use under asphalt shingles and most metal roofing systems¹
• Convenient:  Available in 2.0 square (200 ft.² [18.58 m²]) rolls – excludes laps
