Finding where water enters an industrial profile or commercial flat roof requires methodical inspection, not guesswork. We trace water travelling along steel purlins, check insulation cores for trapped moisture, and inspect sheet laps to pinpoint the actual failure point before specifying work.

Commercial roofs take severe weather exposure across wide, exposed spans. We treat cut-edge corrosion with durable coatings, install heavy single-ply membranes or cold liquid around awkward rooftop air handlers, and reline leaking box gutters to stop rainwater backing up under sheets.

Commercial property managers and leaseholders need plain facts, not vague summaries. We supply itemised photographic defect reports detailing sheet condition, fixing degradation, and rooflight UV damage so you have exact records for lease handovers, insurance claims, or planned maintenance budgets.
