Roofing Systems
EPDM.
Sixty years of documented performance.
Synthetic rubber membrane with the longest field track record of any single-ply commercial roofing system on the market. Documented for thirty-year-plus service life across thousands of buildings since the 1960s.
Best For
Industrial buildings, offices, warehouses, schools and government facilities, and large open-roof buildings in cold or temperature-cycling climates.
Service Life
20-30 years.
EPDM has the longest track record of any single-ply commercial roofing system on the market. It’s been protecting commercial roofs since the 1960s, and the field data showing thirty-year-plus service life isn’t speculation. It’s documented across thousands of buildings.
How It Works
Synthetic rubber, taped seams, no heat.
EPDM is a synthetic rubber membrane. Where TPO and PVC are heat-welded, EPDM seams are bonded with adhesives or factory-applied tape. The trade-off: EPDM doesn’t reflect heat the way white membranes do, so it’s a lower-energy-performance choice, but it handles cold and temperature swings better than any single-ply on the market.
Operational Profile
Long service life, lower energy performance.
Low maintenance, minimal install disruption, low foot-traffic tolerance, lower energy performance than reflective white systems. EPDM’s strength is documented longevity and cold-climate flexibility, not energy savings.
What You Should Know
The seam adhesive is the weak link.
Older EPDM installations (pre-2000s) used field-applied seam adhesives that are the most common failure point on aging EPDM roofs. Modern factory-applied tape systems have largely solved this, but it’s a detail worth verifying in any bid. Insist on factory tape, not field adhesive, on any new installation.
Where It Falls Short
Reflectivity.
Black EPDM absorbs heat. In hot climates, that means higher cooling costs compared to white TPO or PVC. White EPDM is available, but it doesn’t have the same multi-decade track record as black.
