Most houses around Newtown Square, Edgemont and Gradyville still carry original or once-replaced asphalt roofs on colonial and ranch stock from the mid-century boom. Those decks sit over attics that see hot, humid summers and then freeze-thaw cycles that pop nails and open valleys. A replacement here is not a cosmetic overlay. We pull everything to the deck, check for rot at the eaves and around the Tyler Arboretum-side trees that dump leaves into gutters, then rebuild with ice-and-water shield in the valleys and drip edge that actually sheds the winter melt instead of trapping it against fascia.
Delaware County code and the realities of West Chester Pike traffic mean we stage dumpsters and materials so we do not block driveways at the Newtown Square Corporate Campus or the narrower streets in Gradyville. Tear-off on a 1970s split-level often reveals plywood that has already been sistered once; we replace only what is unsound rather than selling a full deck swap. Steep pitches common on older farmhouses need extra fall protection and extra ice membrane at the north-facing slopes that hold snow longest. We schedule around the weekday 8am–6pm window so crews are off the roof before the evening commute through Media and Broomall.
Metal and architectural shingle choices both work, but the humid summers here cook dark shingles and the winters crack cheap underlayment. We match the existing ventilation so the new roof does not cook the attic or ice-dam the eaves the first January. If the house sits near low-lying spots off Gradyville Road, we add extra flashing at chimneys and skylights because wind-driven rain finds every gap. The job ends with a clean yard, magnetic nail sweep, and photos of the deck so you can see what was actually under the old shingles.
Technician insight
In Newtown Square the thing that catches most people out with roofing replacement is the second layer of shingles sitting on plywood that was never meant for two roofs, especially on the 1960s–70s stock near Edgemont. Once winter temperatures drop, that extra weight plus ice dams at the eaves pops nails and the leak shows up in the ceiling the first thaw. We always pull to the deck so we can see whether the plywood is still sound or already sistered once.
Gradyville ranch with ice-dam leaks after two winters
Homeowner had a second layer of 3-tab shingles and water stains at the north eaves every thaw. We tore off both layers, found two sheets of plywood already delaminated at the valley, replaced those, added ice-and-water shield six feet up the eaves, and installed architectural shingles with new drip edge. The attic stayed dry through the next freeze-thaw cycle and the magnetic sweep left the yard clean.
Roofing Replacement Services We Offer
✓Asphalt Shingle Roof Replacement
Full tear-off and architectural shingle install sized for the freeze-thaw and summer heat that hit Newtown Square and Edgemont roofs.

Standing-seam or exposed-fastener metal that sheds snow and ice better than shingles on the steeper colonial roofs around Gradyville.
✓Ice and Water Shield Upgrade
Extra membrane in valleys and eaves so winter melt from Delaware County storms does not leak into older attics.
✓Roof Deck Repair and Sistering
Replace or reinforce plywood that has already been patched once on mid-century homes near the Corporate Campus.
✓Chimney and Skylight Flashing Rebuild
New step and counter flashing so wind-driven rain off the Arboretum ridge does not find the old gaps.
✓Attic Ventilation Correction
Balance intake and exhaust so the new roof does not cook the attic in July or ice-dam the eaves in January.

How it works
- 1
On-Site Measure And Deck Check
We walk the roof in Newtown Square or nearby Media, note pitch, existing layers, and any rot at eaves or valleys before quoting.
- 2
Tear-Off And Dumpster Staging
Old material comes off to the deck; dumpsters sit so they do not block West Chester Pike traffic or tight Gradyville streets.
- 3
Deck Repair And Underlayment
Unsound plywood is replaced, ice-and-water shield goes in the valleys and eaves, then synthetic underlayment.
- 4
Shingle Or Metal Install And Flashings
New covering, drip edge, and rebuilt chimney/skylight flashings go on, then ridge vent and magnetic nail sweep.
- 5
Final Walk-Through
You see the deck photos, the clean yard, and the completed roof before we leave.
Pricing
Most full replacements on typical Newtown Square colonials and ranches land in the mid-to-high four figures to low five figures depending on squares, pitch, and how much deck needs repair. We give a written scope after we see the roof, not a phone number.
