Abstract
During installation of a single-ply roofing membrane, the surface of the membrane can be protected from dirt, scratches and scrapes by a protective sheet which also provides other beneficial attributes that aid an installer. A roof laminate includes a roof membrane and a protective sheet is removably affixed thereto. The sheet includes at least a first layer directly secured to a second layer. The first layer provides at least one of UV protection, anti-slip, and anti-glare to the roof laminate and so aids the installer in at least one of those respects. The second layer is removably affixed to the roof membrane.
