Commercial roofing guide
Drainage problems can keep water on the roof longer than the membrane, seams and flashing were intended to handle.
Flat and low-slope commercial roofs rely on drains, scuppers, gutters and designed slope to move water away. Debris, settlement and blocked outlets can create persistent ponding or overflow.
Quick answer
Commercial roof drainage problems should be addressed by restoring safe drainage and identifying why water is collecting. The surrounding membrane, seams, insulation and deck should also be checked for moisture damage.
Commercial property checklist
Leaves, sediment and rooftop debris can reduce drainage capacity quickly during heavy Gulf Coast rain, allowing water to spread across low areas.
Structural deflection, compressed insulation or original slope conditions can create depressions where water repeatedly collects even when drains are clear.
Fixing an open seam without addressing the water that repeatedly sits over it may lead to another failure. Drainage and membrane condition should be evaluated together.
