Commercial Flat Roof & Drain Failure

Low-slope commercial roofs depend on internal drains, scuppers, and crickets to move intense Florida rainfall off the membrane. When drains clog with debris, scupper blocks fail, or seams open at parapets and curbs, water ponds—and then finds paths through fasteners, skylights, and rooftop door thresholds into top-floor ceilings and MEP rooms.

Unlike steep residential slopes, commercial decks often leak slowly into insulation until multiple ceiling areas show failure at once. Hurricane bands and afternoon thunderstorms overwhelm marginal drainage quickly.

We extract water from affected interiors, dry roof decks from below where accessible, coordinate emergency tarping when the membrane is compromised, and document layers for insurance while roofing contractors repair the envelope.
