Serving Cowan and Delaware County
A significant portion of homes in Cowan were built between 1955 and 1985 — a period when roofing materials and installation standards were different from today's code requirements. The original organic felt underlayment on these roofs is long past its service life. The galvanized steel flashing has typically corroded through at one or more points. The 3-tab shingles, if original, have exceeded their design life by a decade or more. We've inspected enough Delaware County homes from this era to know what we're likely to find — and what it means for the homeowner.
We've been working in Cowan and the surrounding area long enough to have re-roofed homes we originally inspected years ago. That continuity is what local reputation looks like in practice.
Delaware County's housing median of 1947 means many Cowan homeowners are managing roofs that have never had a professional inspection. Most roofing problems develop gradually — a sealant that cracks over three seasons, a flashing that lifts each winter and reseats less fully each spring — and only become expensive when allowed to run long enough. We catch these problems at the addressable stage, before they become structural.
