EPDM Roofing Services
Rubber membrane roofing that has been on flat roofs for fifty years.
EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane that has protected flat commercial roofs for more than fifty years. It is flexible in cold weather, resistant to UV and ozone, and available in large sheets that minimize seams. Thousands of office parks, warehouses, and apartment buildings across the DMV are roofed with EPDM today.
TopKey installs new EPDM roofs, repairs existing ones, and helps owners decide when an aging EPDM roof should be restored, recovered, or replaced. Our crews are trained on fully adhered, mechanically attached, and ballasted EPDM systems. We use Elevate RubberGard EPDM (formerly Firestone) as our standard membrane. It is the most widely installed EPDM in North America and is backed by Elevate manufacturer warranties.

Addressed the hot water heater and fountain wiring issues which were outside of the original scope of work. The overall work performed was outstanding and within the scheduled time-line despite some unforeseen items that arose with the warehouse demo portion. Thank you!”

FAQ
EPDM Roofing Questions, Answered
How long does an EPDM roof last?
Twenty to thirty years with routine maintenance. Seam and flashing inspections every year or two are the key to reaching the upper end.
Should I replace my EPDM roof with TPO?
If your EPDM roof is sound, restoration or repair is usually the better investment. When it is time to replace, TPO is often chosen for its reflectivity, but EPDM remains a strong option, particularly where black membrane and cold-weather flexibility matter.
What causes EPDM roof leaks?
Most EPDM leaks come from seam adhesive failure, shrinkage pulling the membrane away from walls and curbs, and flashing deterioration. All are repairable.
