EPDM Rubber is one of the most common low-slope roofing systems for residential homes featuring low-slope or flat roofs, today.
EPDM in a Nutshell
Rubber membranes for low slope and flat roofs are made from EPDM rubber, a type of synthetic rubber characterized by a wide variety of applications.

The E in EPDM refers to Ethylene, P refers to Propylene, D refers to Diene, and M or Monomer refers to its classification.
The properties of natural rubber are modified to serve the purpose of synthetic rubber — synthetic rubber has improved weather resistance qualities as a result.
Cost
Expect to pay between $6.50 and $11.50 per square foot to install EPDM membrane on a typical flat roof, or about $9,750 to $17,250 for a 15 square (1,500 square feet) low-slope roof replacement.
The cost may be higher or lower depending on the tear-off and removal cost of the existing roof, insulation layers, and the number of penetrations on your flat roof.
