WeatherMaster® Ice & Water provides a secondary layer of waterproofing protection needed to help prevent damage from ice dams and wind-blown rain. These self-adhering modified-bitumen underlayments create a watertight barrier by sealing to the deck and around nails to provide continuous protection year after year. WeatherMaster® Ice & Water helps protect the entire deck of a properly ventilated roof or just those problem areas where water collects or drainage is slow. And since it can go under any roofing material from asphalt shingles to tile, homeowners can enjoy maximum protection with the architectural look they want.
WatherMaster® Ice & Water underlayment is self-adhesive and cold-applied. No special adhesives, heat, or equipment are necessary to install under normal dry conditions of 45°F or warmer.
