It is ideal for slopes 2:12 or higher and can be used under a variety of roofing materials, including asphalt shingles, cedar or metal roof cladding.

It is wrinkle-free, easy to chalk, protects the roof during installation as a moisture barrier and withstands UV exposure for up to 3 months. It is trusted protection that can give both professional builders and homeowners greater peace of mind.
