Cool roof rating council energy star.
Energy savings from installing energy star or cool roofs rating council labeled roof products depend on the local climate existing insulation levels the type of roof replaced the type of roof installed and maintenance.
It is important to note that any roof covering product can be listed in the cool roof rating council database.
Just because a product appears in the database does not necessarily mean it meets the requirements of either title 24 or energy star.
Single ply membranes are pre fabricated sheets rolled onto the roof and attached with mechanical fasteners adhered with chemical adhesives or held in place with ballast gravel stones or pavers.
