What this work involves

TPO (thermoplastic polyolefin) is a heat-welded single-ply membrane used on many low-slope commercial roofs in this area. Repair work is usually patches and flashings welded to the existing sheet. Replacement is a new TPO system with the insulation, cover board, edges and drains the building needs. We also have project photographs from TPO inspections and repairs in Affton and Wildwood.

  • Heat-welded repairs and flashings
  • Drain and penetration details
  • Recover or tear-off replacement when the sheet is worn out

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 both repair and replace TPO?
Yes. A puncture or a failed flashing can be a repair. A brittle or repeatedly leaking sheet is usually a replacement conversation.
Is TPO the only single-ply you work on?
No. We also work on EPDM and PVC. The inspection tells us what is on the roof now.
