Single ply roofing membranes with multifunctional biodegradable release liner

摘要

A roofing laminate includes a roofing membrane, preferably a white roofing membrane, which is covered with a protective sheet. The protective sheet is tinted so that it has a coloration distinguishable from the roofing. The roofing laminate is applied to a roof surface and the release liner protects the outer surface of the membrane from scrapes and dirt during installation. Once the roof is installed the protective sheets are removed from all of the membrane sheets, exposing a clean surface.
