Newtown Square and nearby Edgemont sit in Delaware County with a mix of mid-century colonials, stone farmhouses, and later subdivisions around the Newtown Square Corporate Campus. Those roofs see humid subtropical swings: hot, wet summers that cook asphalt and drive algae, then cold winters that push ice dams at eaves. When we install a new roof we size underlayment and ice-and-water shield for freeze-thaw, not just a generic tear-off. Steep pitches common on older stock around Tyler Arboretum change staging and fall protection; low-slope sections over additions need different membranes so water does not pond after a Media-area thunderstorm.
Tear-off on these houses often reveals original decking that has cupped or been patched after prior leaks. We inspect for rot at valleys and around chimneys before new felt goes down, because Delaware County soil stays damp and attic ventilation is frequently undersized. Code in this part of Pennsylvania expects proper drip edge, ice barrier in the eaves, and fastening that holds through wind events that funnel between Wayne and Broomall ridges. We do not claim extra credentials; workmanship is what you can walk and look at when we are done. Hours are Monday–Friday 8am–6pm and Saturday 9am–2pm from 3475 West Chester Pike.
Material choice here is not fashion. Architectural shingles handle the temperature range if ventilation is right; standing-seam metal sheds snow better on north slopes that stay shaded. We match existing flashing metals so galvanic issues do not start at the first spring rain. Homeowners sometimes want the cheapest three-tab overlay; that fails faster on older rafters that have already settled. A full tear-off lets us correct decking and add intake at the soffit so the new roof actually lasts through another decade of Newtown Square summers.
Technician insight
In Newtown Square the thing that catches most people out with residential roofing is assuming a new shingle layer will fix ice dams. Older attics around here often have almost no soffit intake, so heat still melts snow at the ridge and it refreezes at the eaves after a cold snap. We have to open the soffits or add baffles while the roof is off, or the next winter looks the same. Terrain near Tyler Arboretum also means more shade and slower drying, so underlayment choice matters more than the color of the shingles.
Ice dam and soft decking on an Edgemont colonial
A homeowner called after repeated ceiling stains following freeze-thaw weeks. Tear-off showed two layers of three-tab, no ice barrier past the first two feet, and several sheets of plywood that had cupped over a poorly vented attic. We replaced the wet decking, ran ice-and-water shield into the valleys and up the eaves, added ridge vent and soffit intake, then installed architectural shingles. Stains stopped the following winter and the attic stayed dry after rain.
Residential Roofing Service Services We Offer
✓Asphalt Shingle Roof Installation
Architectural shingles chosen for Delaware County heat and freeze-thaw, with ice barrier at eaves so ice dams do not back up into attics on Edgemont colonials.
✓Metal Roof Installation
Standing-seam or exposed-fastener metal for north-facing slopes that hold snow longer near Tyler Arboretum, reducing ice-dam risk without extra load on older framing.
✓Roof Tear-Off and Replacement
Full removal of existing layers so we can repair cupped decking common on mid-century Newtown Square homes before new underlayment goes down.
✓Ice and Water Shield Installation
Self-adhered membrane at eaves, valleys, and penetrations sized for cold winters that follow humid summers, not a thin strip that stops at the first rafter.
✓Roof Ventilation Upgrade
Soffit and ridge venting balanced so hot summer air exits instead of cooking shingles on low-slope additions around Gradyville.
✓Flashing and Chimney Cricket Work
New step and counter flashing plus crickets on wide chimneys so water does not sit after storms that roll in from Media and Wayne.
