WeatherWatch^® Mineral-Surfaced Leak Barrier is a key part of the GAF Lifetime^† Roofing System. It's eligible for a Lifetime^† Limited Warranty when installed with GAF Lifetime^† shingles and at least two additional qualifying GAF accessories and may be eligible for residential enhanced warranty coverage¹. 

How does WeatherWatch^® Protect your Roof?

By creating an extra layer of protection at certain areas of your asphalt shingle roof (at the eaves and rakes, in valleys and around chimneys, etc.), WeatherWatch^® Mineral-Surfaced Leak Barrier helps prevent leaks due to water backing-up in your gutters, wind-driven rain and in the North, damaging ice dams.

• 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.
• Strong Protection: Helps guard areas of your roof against leaks including eaves and rakes, in valleys, around chimneys and skylights, and more.
• Dependable: Self-seals around nails to help reduce the risk of leaks.
• Fiberglass-reinforced: Helps resist buckling and wrinkling that can detract from the look of your finished roof.
• Split-back Release Film: Peels off in layers for fast installation.
• Convenient: Available in 1.5 square (150ft.² [13.9 m²) and 2.0 square (200 ft.² [18.58 m²]) roll size.
