WeatherLock® Mat Self-Sealing Ice & Water Barrier is designed to act as a secondary water barrier under shingles, wood shakes and quarry slate roofs. It helps prevent damage due to shingles being blown off, as well as wind-driven rain which can get under shingles and ice damming.
It also:
Acts as another line of defense when used on the entire roof deck, part of best practices for roof deck coverage on 2:12 to 4:12 pitch roofs*
Is effective at reducing slipping, sticking and scuffing thanks to a patented roughened surface
Is lighter weight than typical granulated products, making it easy to load, carry and install
WeatherLock® Mat Self-Sealing Ice & Water Barrier is an essential part of the Owens Corning™ Total Protection Roofing System™§.
