Roofing in Delaware County, PA
Delaware County's inner suburbs look a lot like West Philadelphia, and their roofs fail in the same places: flat rear roofs, shared parapets and twin-house shingles.

In Delaware County's inner suburbs most roof calls are rowhouse and twin roofs: flat membranes on rear roofs, porch roofs, shared parapets between houses and shingle front slopes on twins. Farther out, Haverford and the Main Line side bring older stone houses with slate.
What the Roofs Look Like Here
Upper Darby borders West Philadelphia and is Pennsylvania's sixth most populous municipality. Its densely built rowhouse sections look like the neighboring city blocks, alongside turn-of-the-century single homes and mid-century developments. With Lower Merion, Haverford and Cheltenham it forms the inner ring of suburbs just west of the city.
That mix means flat roofs over rowhouses and rear additions, porch roofs along twin-house streets in Drexel Hill and Highland Park, and shingle or slate on the singles. Shared parapets and party walls make leaks between neighboring houses a common call, just as they are in Philadelphia.
Work We Do Most in Delaware County
Flat roof repair and replacement on rowhouses and rear additions, porch roof repairs, parapet and coping work between attached houses, shingle replacement on twins and singles, and gutter repairs on older houses where downspouts feed into old drain lines.
A Typical Job in Delaware County
On an Upper Darby rowhouse, a flat roof replacement usually takes a day or two: old layers off to the deck, new membrane with the slope improved toward the scupper, and new flashing up the parapets and into the neighbor's roof. On twins, the front shingle slope and the flat rear roof often fail at different times, and we price them separately so you can choose.
Leaks between attached houses are common here. We trace the water to the side it enters, photograph it and repair the joint, which matters when two owners share the cost.
