EPDM rubber is one of the most common low-slope roofing systems for homes featuring low-slope or flat roofs.
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.
Most homeowners can expect to pay between $7.50 and $12.50 per square foot to install a new EPDM rubber membrane on a typical flat roof. This translates to a total project cost range of $11,250 to $18,750 for a typical 15-squares (1,500 square feet) low-slope roof replacement.

The total project cost can be higher or lower depending on the condition of the existing roof and the underlying deck, type and thickness of insulation, and the number of roof penetrations like chimneys and skylights. The overall roof difficulty, accessibility, and project location will also greatly impact costs.
For comparison, PVC and TPO roofs cost an average of $8.50 to $14.50 per square foot installed, including materials, professional installation, and labor warranty.
