First, Modified Bitumen Roofing – MBR
A modified bitumen roofing system is a single-ply roofing system that modifies asphalt with polymers, with fiberglass or polyester reinforcement to make it more durable. According to Lifetime Flat Roofs, it is more durable than BUR, but not as much as EPDM. Due to its resistance to UV damage, it is ideal for areas that receive a lot of sunlight.

Up next, EPDM
Ethylene Propylene Diene Monomer is widely used in commercial flat roofing, along with residential. It is highly durable, resistant to temperature change, and UV radiation. The flat roof lifespan is around half a century, making it a solid choice for homeowners.
-
Last but not least, metal roofs
By far the most durable out of all three roofs, metal roofs are made of copper, tin or steel. They can last for over 50 years and require little maintenance. What’s more is that they are the most energy-efficient roofing among all three, making them a smart investment choice.
