By creating a barrier at the most vulnerable areas of your roof (at the eaves and rakes, in valleys, around chimneys, etc.), weather watch® leak barrier will help prevent leaks due to water backing up in your gutters, wind-driven rain, and, in the north, damaging ice dams. It will also protect your home from expensive wall and ceiling staining from leaks.
Looks better: underlayment with fiberglass reinforcement helps resist wrinkling/buckling and lies flat under Shingles
Saves labor: dual-side selvage and split-back release film help reduce labor
Dependable: self-seals around nails or metal roofing fasteners
Protection against ice dams; is required wherever the January average temperature is 25° F or lower or where there is a possibility of ice forming in the eaves (check local building codes for specifications in your area)
Dependable because it self-seals nails and vulnerable areas of the roof to help avoid leaks
Great look fiberglass reinforcement helps resist wrinkling for a more uniform look
Saves labor split-back release film helps make installation easy
