Pittsburgh's humid continental climate with cold winters and warm summers wrecks flashing fast. Ice dams form on older homes in Squirrel Hill and Point Breeze, forcing water under step flashing on brick chimneys. We cut out the damaged sections and install new 16 oz copper step flashing nailed into the mortar joints instead of relying on caulk that fails in a year.
Cheap crews often slap on sealant over rusted galvanized flashing instead of pulling it and redoing the counter flashing. That mistake shows up every spring on houses in Lawrenceville and the South Side. Allegheny County permit rules require proper overlap and weep holes on any flashing work that touches masonry, so we pull permits on bigger jobs to keep it legal.
Valley flashing on slate roofs in Shadyside and Regent Square leaks when the old lead gets punctured by foot traffic or tree debris. We use 24-gauge stainless valley pans with hemmed edges and fold them under the slate courses so water has a clear path to the gutters. Jobs usually take one day unless we hit rotted decking under the old metal.
When to Call for Flashing Repair
Ice buildup after a freeze-thaw cycle or water stains on ceilings near the chimney means flashing has failed. We show up with 24/7 emergency service and can often patch the spot same day if the rest of the roof is sound.
