Pittsburgh houses in places like Squirrel Hill and Shadyside often have two or three layers of old asphalt shingles from the 1970s and 1980s. Those layers trap moisture when the humid continental climate brings warm summer rains after cold winters. We always tear down to the deck on replacement jobs so the new roof does not fail in five years like the cheap overlays do.
Ice dams form fast along the Ohio River valleys and in Lawrenceville when nights drop below freezing. We add extra ice-and-water shield along the eaves and valleys on every replacement. That step meets Allegheny County requirements and stops leaks that show up at the ceiling in March.
Mount Washington and Point Breeze homes with steep pitches need proper ventilation to handle the temperature swings. We install ridge vents and baffles so the attic does not cook in July or freeze pipes in January. Skipping vents is the main mistake we see from out-of-town crews that rush jobs.
Strip District warehouses and East Liberty storefronts sometimes need commercial flat roof sections tied into the pitched work. We use 60-mil TPO or EPDM on those flat areas and flash them to the shingles so water does not back up under the new roof.
