Pittsburgh roofs take a beating from the humid continental climate with cold winters and warm summers. Ice dams build up along eaves in winter then melt and push water under shingles. We see this often in older homes around Regent Square and Point Breeze. Flashing around chimneys and vents fails first because the metal expands and contracts with the temperature swings. Cheap crews skip the step of lifting the shingle course above the leak so water still finds a path back in.
Asphalt shingles are the most common material we work with here. When a leak shows up in the attic we start by checking the underside of the deck for dark streaks or soft spots. In Lawrenceville and the South Side many row houses have tight access so we use a 24-foot ladder and roof jacks instead of staging. We carry 30-pound felt and ice-and-water shield on the truck because the code in Allegheny County wants extra protection at the eaves on steep pitches.
A common mistake is slapping tar over the leak from the outside only. That covers the symptom for a season but the rotted decking underneath keeps spreading. We cut out the damaged plywood, sister in new 5/8-inch CDX, then weave in matching shingles so the repair blends. In Mount Washington homes the wind hits hard so we use six nails per shingle instead of four on the exposed edge.
Why Leaks Show Up After Storms
Heavy summer rain followed by quick temperature drops is the one-two punch that opens seams we missed on the first visit. We always run a hose test after the fix and check the ceiling below for new spots. Homeowners in Bloomfield and East Liberty call us most after August thunderstorms because the gutters overflow and water backs up under the first course.
