WeatherMaster® Pro-Grade Ice & Water
Premium-grade WeatherMaster® Pro-Grade Ice & Water is a fabric-faced, high-temperature, modified composite roof underlayment suitable for all roofing applications.
WeatherMaster® Pro-Grade Ice & Water underlayment is self-adhesive and can be used either as primary underlayment or as flashing tape to provide a secondary water barrier. Its SBS-modified asphalt coating prevents moisture entry by sealing uniformly around nails.
