Help Protect Your Home From Wind-Driven Rain And Damaging Ice Dams With A Waterproof Leak Barrier

A Quality Leak Barrier Will:

WeatherWatch®, a quality leak barrier, will:

Help protect your home from costly wall and ceiling staining

Help prevent leaks due to water damming in your gutters, wind-driven rain, and, in the North, damaging ice dams

WeatherWatch® Leak Barrier is a key part of the GAF Lifetime Roofing System (See Details) , and has even earned the prestigious Good Housekeeping Seal (U.S. only) (See Details)

Don’t Put Your Home At Risk

The Codes Are Clear...
North Area Protection against ice dams is required* at eaves wherever the January average temperature is 25°F or lower or where there is a possibility of ice forming in the eaves—i.e., the area labeled “North.”

But Be Prepared...
Ice dams still occur where the average temperature is above 25°F.

Reduce The Risks...
If you are in an area that requires leak barrier protection – and there is a leak – you could be putting your insurance coverage at risk by not installing it!

* Check local building codes for specifications in your area.
