Woonsocket School District

It did not, but the fix was never going to be a fresh coat of anything. Coating a wet roof seals the water in. Coating a flat roof that ponds just puts a new surface on the same problem, and in a few seasons the district would have been standing in the same place. The roof needed the moisture out and the water moving.

So that is where A-1 started. The saturated foam was cut out and replaced section by section, and then — the part that actually solved it — additional spray foam was built up across the field to create positive slope, so water runs to the drains instead of sitting on the membrane. Spray foam is one of the only roofing materials that can be sprayed thicker in one place than another, which is what makes re-sloping a finished roof possible at all without touching the deck.

Only then did the roof get its surface. Gaco S20 silicone went down over the whole field as a seamless membrane, chosen specifically because silicone is unaffected by ponding water — the exact condition that had destroyed the original system. Sixteen working days, start to finish, with only minor interruption to the school's activities, and the district ended up with a 20-year manufacturer NDL warranty on labor and material.

Two years later a hailstorm cut the membrane open across the roof. Because the system was warranted and restorable, that did not mean starting over: each impact cut was repaired individually with reinforced flashing-grade silicone, the roof was washed down, and a fresh S20 topcoat brought the whole field back to new condition. Six days, zero disruption to the school, and the 20-year warranty was reinstated. That is the argument for a restorable roof in one paragraph — the same storm on a conventional membrane is a claim, a tear-off, and a construction schedule wrapped around a school year.
