EPDM rubber roofing is a flat roof full of flexibility and durability. They are commonly used on low-slope buildings in place of shingles. Shingles require a certain amount of gravity that flat and low-slope roofs don’t have. Although shingles are great, rubber roofing is the way to go if you have a flat or low-slope roof. EPDM rubber roofing is one of the most sustainable and environmentally responsible choices.
