Commercial Roof Repair & Maintenance in Greenville, SC
Commercial roof repair for Greenville and Upstate SC buildings: find the real cause of a leak, fix it properly, and keep the roof on a maintenance schedule so small problems don’t become replacements.
Repair what's actually wrong
Water travels, so the stain on the ceiling is rarely where the roof is failing. OTC traces leaks to their source, such as a split seam, a failed curb flashing, a loose coping or a clogged drain, and repairs it with materials compatible with your roof system.

Repairs
- Single-ply (TPO, PVC) and EPDM membrane and seam repairs.
- Curb, penetration, wall and perimeter flashing repairs.
- Metal roof, trim, gutter and coping repairs.
- Shingle and residential roof repairs.
Storm damage
After wind or hail, we inspect, photograph and document damage, provide temporary protection when needed, and guide you through the insurance claim process as far as we're allowed.
Maintenance programs
Regular inspections catch open seams, failed sealant, clogged drains and damaged flashings while they are still cheap to fix. They also help keep manufacturer warranties in good standing. Ask about a maintenance schedule for your building or portfolio.
Repair or replace?
When a roof has widespread wet insulation, failing seams or repeated leaks, repairs stop being a good investment. We will show you what we found and price both paths honestly.
