We ask whether water appeared near a dining table, prep line, cooler or exhaust hood, then compare that location with the roof layout. Kitchen exhausts, make-up air units, duct supports and utility lines can create several flashing points. We inspect the curb, membrane or panel around each opening, nearby seams and the route to the nearest drain. A roof opening may not sit directly above the stain, so we record the likely water path and the evidence still needed to confirm it.
Grease residue, routine equipment service and foot traffic can affect the surface near exhaust fans. We inspect for loosened fasteners, worn sealant, cuts and damaged flashing, while avoiding assumptions about what caused the condition. If moisture may extend into insulation, a focused moisture survey or test opening can help establish the boundary. We note any area where a hood or ventilation contractor should coordinate before a roofing repair proceeds.
Roof access near a commercial kitchen should account for foot traffic from service vendors and the route staff use to maintain fans or ductwork. We record equipment clearances and note any grease buildup, loose support or sealant condition that could affect the flashing repair. The roof scope should state whether cleaning, equipment adjustment or roofing is responsible for each step. If the ventilation contractor must remove a component, we plan the roof opening after that work and inspect the finished interface before closeout. A clear sequence avoids leaving a curb detail between trades.
