Low-Slope Metal Roof Repair in Pittsburgh, PA
Low-slope metal roofs on warehouses, shops and older commercial buildings leak in their own way. Exposed fasteners back out as the panels expand and contract, and the rubber washers under them dry and crack. Laps between panels open up. Rust starts at cut edges and around fasteners, and flashings at walls, curbs and skylight panels fail. Most of that is repairable: fasteners replaced with oversized ones and new washers, laps sealed, rusted spots treated or panels replaced, and flashings rebuilt. If the metal is still sound but the roof leaks in many places, a coating system with reinforced seams and fasteners can often stop it for years without tearing the roof off.

Move belongings away from the drip, shut off power to any wet light fixture, and stay off the roof in a storm or on ice. Then request service: an active leak can usually be dried in until the permanent repair.
