Explore when flat roof is an option

Just like any roof, there isn’t one system that’s the perfect fit for all flat roofs, also known as a low slope roof. EPDM (ethylene propylene diene terpolymer) is a rubber roofing system that is preferred by many Canadian roofing companies for its durability and cost-effectiveness.

EPDM is made of a versatile rubber membrane made to withstand the elements, including hail and other inclement weather we often see in Calgary.

Modern residential flat roof systems typically have a continuous membrane covering, which allows it to better resist standing water. Other options include modified bitumen (asphalt) or built-up roof materials (BUR). Send us a message today to find out more about our flat roofing services.
