Abstract
A roofing membrane includes first and second layers. The first layer includes a low surface energy polymer. A method of installing the roofing membrane includes, along an edge of a first membrane, mechanically removing a portion of the first membrane extending vertically to include the first layer and a portion of the second layer to leave a flap of the first membrane, placing an edge of a second membrane to overlap the first membrane, and bonding the first membrane to the second membrane. The underside of the edge of the second membrane overlies the flap of the first membrane.
