By creating an extra layer of protection at the certain 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. StormGuard^® Film-Surfaced Leak Barrier is a key part of the GAF Lifetime Roofing System.^† It’s eligible for a Lifetime^† ltd. warranty when installed with GAF Lifetime^† Shingles and at least two additional qualifying GAF accessories and may be eligible for residential enhanced warranty coverage.¹  It’s also covered by up to a 10-year ltd. warranty² when used with other approved non-asphaltic roof coverings.

• Code Compliance and Risk Reduction: Many building codes require ice and leak barriers at the eaves in colder Northern climates to help reduce the risk of leaks caused by ice dams. In warmer Southern regions, these products help protect against leaks caused by wind-driven rain.³
• Strong Protection: Helps guard areas of your roof against leaks including eaves and rakes, valleys, around chimneys, skylights, and more.
• Blue Synthetic Surface: Durable, patterned film surface provides excellent wet/dry traction for installers.
• Integral Surface Channels: Helps move moisture away from the walking surface.
• Cooler to Work on: The blue surface is cooler to work on (than typical black underlayments).
• Versatile: 250°F high-temperature compound is perfect for use under asphalt shingles and most metal roofing systems.⁴
• Convenient: Available in 2.0 square (200 ft.² [18.58 m²]) rolls.⁵
• Simple installation: Dual selvage edge allows for bi-directional roll-out.
