What is the average unit weight of non-ballasted EPDM roofing systems?
The weight of a roofing system varies depending on components used. After combining the weight of components (i.e. insulation, membrane, fasteners, and adhesive), typical installation weight is less than 2 pounds per square foot (10 kg per square meter) when .060″ thick membrane (typically weighing 1/3 pound per square foot or 1.6 kg per square meter) is utilized.
