"Protect Your Investment And Safeguard Vulnerable Areas"
Protect Your Property... Help prevent wind-driven rain from leaking through the roof deck, or melting ice and snow (caused by ice dams in harsh winter climates) from leaking into property’s interior
Add Extra Protection... In valleys and at eave and rake edges — the most leak-prone areas of the roof. Strongly recommended for chronic problem areas like skylights, dormers, vent pipes, chimneys, and other flashing areas
Won’t Leak... Helps ensure a 100% watertight seal
Avoid Costly Repairs... Due to staining on interior walls and ceilings
Better Appearance... Fiberglass reinforcement helps resist wrinkling and buckling — lays flatter under shingles
Saves Labor... Split-back release film peels off in sections, for faster installation and superior property owner value
Peace Of Mind... Benefits from the same warranty term as the shingles they are applied under, up to a maximum of 30 years*

Protect Your Home From Wind-Driven Rain And Damaging Ice Dams With A Waterproof Leak Barrier
IMPORTANT NOTE:The product Information Sheet for Weather Watch® Leak Barrier with a print date of 10/07 listed the incorrect information that Weather Watch Leak Barrier was made with a “high temperature compound” and was “suitable for use with most metal roof applications”. This product isnotmade with a high temperature compound and it isnotsuitable for use under any metal roof. The incorrect information was listed on the web site from October 15th -18th 2007 and distributed in hard copy form, October 1st – October 18th 2007. A Quality Leak Barrier Will:
Create a 100% watertight seal that keeps water out at the most vulnerable areas of your roof (at the eaves and rakes, in valleys, around chimneys, etc.).
Weather Watch®, a quality leak barrier, will:
Protect your home by preventing costly repairs due to wall or ceiling staining
Help prevent leaks due to water damming in your gutters, wind-driven rain, and, in the North, damaging ice dams
Weather Watch®leak barrier is a key part of the GAF Smart Choice®Roof System Solution.
Don’t Put Your Home At Risk
The Codes Are Clear...
Protection against ice dams isrequired* at eaves wherever the January average temperature is 25°F or lower or where there is a possibility of ice forming in the eaves
But Be Prepared...
Ice dams can still occur in areas where the average temperature is above 25°F (not to mention wind- driven rain)
Avoid The Risks...
If you are in an area that requires leak barrier protection – and if there is a leak – you could be putting your insurance coverage at risk by not installing it!
