COMMERCIAL ROOFING IN MISSOURI

Commercial roof repair

When a commercial roof is leaking or a detail has failed, we inspect it, photograph what we find and repair the area that will hold — or tell you when a repair will not.

What this work involves

Commercial roof repair on this site means finding the source of a leak or a failed detail and fixing that area on the system that is already there. We work on TPO, EPDM, PVC, modified bitumen and commercial metal. A repair is not a replacement. If the membrane is at the end of its life, the estimate will say so.

  • Leak tracing on an occupied building
  • Seams, punctures, flashing and drain details
  • Edge metal and coping repairs
  • A written scope when the repair will not be enough

How we handle it

  1. You tell us about the building and what you are seeing.

  2. We inspect the roof, photograph what we find and review it with you.

  3. You receive a written, itemized estimate before any work is scheduled.

  4. We pull the permit when the job requires one, and the details of the workmanship warranty are on the certificate for that job.

  • The roof inspection is free. (read 24 Oct 2026)
  • Inspections documented with photos of what we found.
  • Our office reads every request and calls you back.
  • GAF Certified

Questions

Can you repair a roof that is still under a manufacturer warranty?
Often yes, but the repair has to be compatible with the system that is there. We look at the membrane and the failed detail and tell you what a repair would involve before anyone starts.
Do you repair metal panel roofs as well as membranes?
Yes. Seams, fasteners and flashings on commercial metal roofs are part of this work. See also commercial metal roofing and the Fenton industrial metal-panel repair in the project pages.
Is the inspection free?
Yes. The roof inspection is free.
