A Punctured TPO Roof: Match the Repair to the Membrane
A punctured TPO roof needs a compatible repair based on the identified membrane and the condition around the opening. The visible hole is the starting location for assessment, not a complete description of the repair scope.
Separate the opening from its consequences
Ask the contractor to document the puncture and determine whether nearby seams, substrate or insulation also need assessment. A small visible opening does not establish how much concealed material is affected. Equally, the opening alone does not prove the whole roof requires replacement.
The JM TPO guide provides system-specific preparation and repair requirements. Ask which instructions govern your membrane, especially where an old coating or patch obscures its identity.
Build two lines into the scope
The first line should describe the confirmed surface repair: location, identified membrane and compatible repair system. The second should describe how additional findings will be handled if inspection reveals a broader problem. This keeps an uncertain condition from disappearing inside the phrase “patch roof.”
Request before-and-after photographs at the same location, plus the verification performed. Leave cleaning, cutting and welding to qualified roofing personnel; avoid putting household sealants over the opening before it is assessed.
Address the damage source
If the puncture is near recently serviced equipment, retain the service dates and photographs without assuming who caused it. Ask whether the proposed work includes checking the access route or equipment interface. A repair record that identifies only the hole may miss the operational issue you need to resolve.
Bring the membrane records and damage location to a commercial roofing discussion so the repair proposal can address both the opening and the unresolved surrounding conditions.
