EPDM Roofing in Greenville, SC
A durable synthetic rubber membrane with decades of history on big low-slope roofs across the Upstate. It stays flexible through temperature swings and is straightforward to repair.
Proven rubber, done properly
EPDM has protected commercial roofs for decades. Large sheets mean fewer seams, the rubber stays flexible in cold and heat, and repairs are simple when they're done with compatible materials. Many existing commercial roofs are EPDM, and OTC repairs and maintains them as well as installing new systems.

What we do with EPDM
- New and replacement systems with insulation, flashings and fabricated edge metal.
- Seam and flashing repairs using compatible tapes, primers and flashings.
- Maintenance: inspections, clearing drains, re-securing edges and addressing aging seams before they leak.
- Replacement assessment: when an old EPDM roof is no longer worth repairing, we will tell you and price the options.
EPDM vs. single-ply thermoplastics
EPDM seams are bonded with tape and adhesive. TPO and PVC seams are welded with heat. Each has its place. We will recommend based on your building, budget and the existing roof.
