EPDM Rubber Roofing Cost vs. PVC and TPO in 2021 – Pros & Cons

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.

EPDM Rubber Roof

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.


Expect to pay between $6.50 and $12.50 per square foot to install EPDM membrane on a typical flat roof, or about $9,750 to $18,750 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, number of insulation layers, and the number of penetrations on the flat roof. The overall roof difficulty, accessibility, and project location will greatly impact costs.
