Repair Manual for Low-Slope Membrane Roof Systems — Asphalt Roofing Manufacturers Association, National Roofing Contractors Association and SPRI (joint publication), 1997.
Source: Asphalt Roofing Manufacturers Association, National Roofing Contractors Association and SPRI (joint publication) · · 1997
A joint publication of ARMA, the NRCA and SPRI, addressed to the professional roofing contractor and organised by membrane type — built-up, modified bitumen, thermoplastic and thermoset — with each repair procedure on its own page so it can be pulled and handed to a crew. Its framing argument is that a repair fixes the problem and not the symptom, and it sorts work into three levels: spot patching of isolated defects, general repairs across the field and flashings, and major repairs paired with maintenance coatings. It is explicit that a repair should be designed to the membrane's remaining service life rather than built past it.
Why a contractor cares. This is the trade's own procedural record of how a permanent repair is made on each membrane type — the document behind a defensible repair scope.
Why a public adjuster cares. Whether a low-slope roof can be repaired or must be replaced is the whole argument on a commercial loss. Three associations agreeing on when spot patching is and is not appropriate outweighs an adjuster's assertion.
