COMMERCIAL ROOFING IN MISSOURI

Commercial roof replacement

When a commercial roof is past a responsible repair, we write a replacement scope for the system the building needs and itemize the work before anyone starts.

Flat roof covered in dark gray granulated modified-bitumen cap sheet, with black membrane running up a long parapet wall and trees against a blue sky beyond.

What this work involves

A commercial replacement is a planned project: access, tear-off or recover where a recover is appropriate, insulation and cover board as specified, the new membrane or metal, flashings, edges and drains. We do not treat a replacement as a surprise add-on to a repair visit. The workmanship warranty on a full roof replacement is the five-year labor and workmanship term in our credentials, with the details on the certificate for that job.

  • Written, itemized replacement scope
  • TPO, EPDM, PVC, modified bitumen or commercial metal, matched to the building
  • Permits pulled when the job requires one
  • Photo-documented inspection before the scope is written

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

Do you always tear the old roof off?
Not always. A recover can be the right scope when the existing roof and the deck will accept it. The inspection is what tells us which path to write.
Which system do you install?
The one that fits the building, the roof structure and how the roof is used — not a single product for every job. The system pages on this site describe TPO, EPDM, PVC, modified bitumen, metal and coatings.
