WeatherMaster® Ice & Water 100
WeatherMaster® Ice & Water 100 is a composite roof underlayment designed to provide a secondary waterproofing barrier needed to prevent ice dams and damage caused by wind-blown rain.
A proprietary fiberglass mat reinforced, SBS-modified asphalt makes WeatherMaster® Ice & Water 100 ideally suited for continuous waterproofing protection against ice dams and wind-blown rain year after year. The self-adhesive underlayment creates a watertight barrier by sealing to the roof deck and around nails. WeatherMaster® Ice & Water 100 provides excellent traction and protection from UV degradation and weathering thanks to its granule surface.
