TPO membrane repair

TPO is heat-welded at the seams, and that is where it fails — along welds that were under-cooked at installation, at T-joints, and around penetrations where the detailing is fiddly. It is repairable almost indefinitely while the field membrane has thickness left, which is why a leaking TPO roof is very rarely a replacement conversation. The one thing that does not work is an adhesive patch: the material bonds reliably only to itself under heat.

What the job involves

  • Seam probe across the full roof to locate failed welds
  • Heat-welded repairs using matched membrane and thickness
  • Inspection of curbs, penetrations and termination bars
  • Core sample where saturation of the insulation is suspected
  • Remaining service life assessment against membrane thickness

Signs you need it

  • Seams visibly open, lifting or peeling at the edges
  • Punctures and scuffing in plant and traffic areas
  • Repairs that were previously patched with adhesive and have lifted

Questions

Someone patched it with adhesive. Is that a problem?

It is a temporary measure that will lift with the first full temperature cycle. TPO is designed to be welded to itself; adhesive patches trap water underneath and often enlarge the affected area. The proper repair is to cut back to sound membrane and weld in a new piece.

How much life is left in our TPO?

Thickness is the honest measure, not age. A core sample tells you the remaining mil and whether the insulation beneath has taken water. Fifteen to twenty-five years is typical, but a roof with saturated insulation is finished regardless of how the membrane looks.

Describe what you are seeing

Low-slope roofs in this climate fail at details rather than in the field, and the damage is usually well advanced before water reaches a tenant space.
