A dark ring at a refrigeration curb can point to a loose corner, a wet insulation layer, or water moving from a nearby drain. We check the curb base, seam, and drain bowl before opening the roof. In West Valley City, UT, grocery work also has to account for receiving traffic and customer entrances. We mark the repair boundary first. The store’s operating window then sets the sequence.
Long roof fields, refrigeration equipment, exhausts, and roof drains create several possible leak paths. A ceiling stain alone does not tell us which layer failed. We compare the interior location with roof conditions and use a test cut when it will change the repair limit. A commercial roof inspection can document those findings before the store chooses a repair or larger scope.
