EPDM, or Ethylene Propylene Diene Monomer, is a synthetic rubber roofing membrane that’s extremely durable and used on buildings around the world that are a 2/12 pitch or lower. It’s available in both black and white, and you can find it in a variety of widths and thicknesses. Cost-effectiveness and durability are two reasons why EPDM roofing is one of the most popular flat roof systems currently used in the United States.
