TPO membrane repair
TPO is a single-ply membrane common on flat and low-slope roofs, heat-welded at the seams. It fails at those welds, at penetrations and curbs, and through punctures from foot traffic or debris. Repair is a welding job rather than a patching one — adhesive patches on TPO are a temporary measure at best, because the material does not bond reliably to anything other than itself under heat.
Call (229) 592-0097What the job involves
- Seam probe across the full membrane to find failed welds
- Heat-welded repairs using matching membrane
- Inspection of curbs, penetrations and termination bars
- Assessment of ponding and drainage contributing to failure
- Check of membrane thickness and remaining service life
Signs you need it
- Seams visibly open or lifting
- Punctures or scuffing in traffic areas
- Ponding water that does not clear

Questions
Can TPO be patched with adhesive?
As an emergency measure only. The material is designed to be heat-welded to itself, and adhesive patches lift at the edges with temperature cycling. A welded repair is the actual fix.
How long does TPO last?
Typically fifteen to twenty-five years depending on thickness and exposure. Seams and detailing fail well before the field of the membrane does, which is why most TPO work is repair rather than replacement.

Describe what you are seeing
On the coast the metal usually fails before the shingles do. Salt corrodes flashing and fasteners from the moment they go on, and the leak shows up at a junction rather than in the middle of the roof.
