“The roof system warranty is especially important when adhering PV panels to BUR, MB, and single-ply weather-proof coverings. White and light-colored roof membranes are used because they reflect heat energy. As a result, their surface temperatures are typically 10 degrees F to 15 degrees F above ambient, which is lower than the surface temperature of dark roof coverings and PV modules. These cool roof membranes are not designed to withstand very high temperatures. A dark PV laminate, meanwhile, absorbs heat energy. The temperature of an adhered thin-film PV product may exceed the maximum temperature limit of a white or light-colored single-ply membrane. The Midwest Roofing Contractors Association (MRCA) is currently researching rooftop temperatures in conjunction with adhered PV laminiates at a site in Manhattan, Kansas."
