Where does the water enter the grocery roof?
The point where a ceiling tile stains may be far from the entry point. Water can travel on top of a vapor retarder, through insulation joints, along deck flutes or around a curb before becoming visible. We compare the reported room with drains, seams, rooftop units, pipe penetrations and roof transitions along a credible path. The goal is to find an opening that can be corrected, not merely cover the symptom indoors.
A store may contain many roof penetrations, but their condition and spacing must be confirmed on site. We inspect membrane laps and patches near refrigeration lines, exhausts and mechanical curbs; check terminations for loose or split flashing; and look for wet insulation that could widen the repair. If the roof surface itself appears sound, a condensate line or plumbing issue may require a different specialist.
The inspection notes should make the location repeatable. A roof plan, equipment tag, compass point or measured offset from a drain can identify the same area for the building contact and a return visit. The notes should separate confirmed defects from possible causes so the owner can authorize a defined repair without treating every nearby penetration as failed.
