Pick the roof for the building, not the brochure.
The right system depends on what happens under the roof, what's on top of it, and how long you plan to own the building. We explain the tradeoffs and recommend one.

Replacement, repair and new roofs for Upstate commercial buildings.
OTC is a commercial and industrial roofing contractor for Greenville, Greer, Spartanburg, Anderson and the rest of the Upstate within about 60 miles.
Commercial flat roof replacement
When a flat or low-slope roof has wet insulation, failing seams or repeated leaks, OTC replaces it: tear-off to the deck, deck and insulation corrections, tapered insulation for drainage, and a new TPO, PVC or EPDM membrane with fabricated edge metal. Where code and a moisture survey allow, a recover can save the tear-off.
Commercial roof repair
Leak tracing and commercial roof repair for single-ply, EPDM and metal roofs: split seams, failed curb and penetration flashings, loose copings and clogged drains, repaired with materials compatible with your system, plus maintenance programs that protect manufacturer warranties.
Industrial roofing
Industrial roofing for Upstate SC plants and warehouses: large-area membrane and standing-seam metal roofs with exhaust, equipment and roof traffic, phased around production and staged for safety on big open roofs.
Big roofs need a plan, not just a crew.
Large commercial jobs succeed or fail on logistics: staging, material hoisting, phasing around tenants and production, keeping the building dry during tear-off, and safety on a big open roof.
- Phased work so occupied buildings stay dry and operating.
- Job-specific safety plans following OSHA-mandated procedures.
- One contractor for membrane, metal and custom sheet metal details.
- Documented closeout with manufacturer warranty paperwork for new installations.
