Roofing contractor in Lansdale, PA

Know the house

Roofs you’ll find around Lansdale.

• Twins and rows near the station

  On an attached house the weak spot is usually where your roof meets the neighbor's: a party-wall flashing that was patched with tar decades ago. We check that seam from both sides of the line and tell you plainly if the fix needs the neighbor's cooperation.

• 1950s and '60s houses

  These are the borough's largest group, and many still carry a second layer of shingles over the original. A tear-off down to the boards lets us find soft decking, which is replaced at the flat per-sheet rate in your contract and photographed.

• Pre-1940 homes

  The oldest houses often have board sheathing, brick chimneys and step flashing that has been sealed over more than once. Chimney flashing is the first place we look when one of these leaks.

• Newer infill and townhomes

  About 600 homes were built in the 2010s. If yours is in an association, the HOA may handle the roof; we can still inspect a leak and give you a report to take to the board.

Freeze-thaw winters and summer storms in the North Penn area

January here averages about 30 degrees, so snow on the roof melts by day and refreezes at the eaves by night. On older houses without ice and water shield at the edge, that water backs up under the shingles. On every roof we replace, ice and water shield goes at the eaves, valleys and penetrations.

Summer storms do their damage too. In August 2021 the remnants of Tropical Depression Fred dropped an EF-1 tornado that ran from Souderton north through Hatfield, ripping siding off homes a few miles from the borough line. After a storm like that, a free inspection tells you whether anything lifted.
