EPDM rubber roofing requires no regular maintenance, We do recommend removing leaves from them if you are in a place where they build up in the autumn. Aside from that they need only be worked on when they are leaking.
Though fully adhered rubber roofing costs a little more than the other two methods of installation it is quite worth it. The length of life they get far outweighs the slightly lower price of the other installation methods.
They are especially beneficial for flat or low-pitch roofs that traditional shingles have trouble effectively protecting due to the lack of gravitational pull.
