The main advantage of EPDM is that is easier to fit to the roof than traditional felt. It is available in wider rolls, and for a smaller roof, it’s often possible to fit it without any joins at all. As joins are often the weak spot where water can start to get into the roof, this is good news for homeowners. Unlike traditional felt which uses blowtorches and heat to fix the felt onto the roof, EDPM is stuck down with special adhesive. EDPM is available in black or white, and gives a smooth and contemporary look to any home.
