FROM OUR PROJECT COLLECTIONRequire a compatible connection and adequate preparation
Commercial roofing membranes and prior coatings have different requirements. The contractor should identify the surface and any repair layers before selecting a patch or sealant. Cleaning and preparation, as well as the condition of adjacent roofing, affect whether the new connection can be made as intended. A generic patching product is not a complete repair specification.
If the visible defect may involve wet insulation or deck damage, request an explanation of how the affected area will be established. Testing or a controlled opening may be recommended. Keep that investigation distinct from the permanent roof leak repair so the scope, fee and decisions that follow are understood.
