Newtown Square and nearby Edgemont sit in Delaware County’s humid subtropical pattern: sticky summers that cook dark shingles and winters that cycle freeze-thaw across roof planes. Standing seam metal handles that swing because the panels clip to hidden fasteners and can expand along the seams instead of tearing at nails. On typical two-story colonials and 1960s–80s ranches here, we start with a dry deck, ice-and-water membrane at eaves and valleys, then 24- or 26-gauge panels in a color that still looks right next to fieldstone and clapboard. Trees around Tyler Arboretum and along West Chester Pike drop leaves and twigs; standing seam sheds them better than asphalt, but we still detail gutters and snow guards so ice does not dump onto walkways at the Newtown Square Corporate Campus or Gradyville driveways.
Slope and existing structure decide whether we can go over a sound deck or must strip to plywood. Many roofs in Media, Broomall, and Wayne were built with 2x6 rafters and mixed sheathing; we check for rot at chimney crickets and low-slope porch ties before any panel goes up. Standing seam is not a one-thickness job: clip spacing, underlayment type, and eave drip all change when the pitch drops below 3:12 or when a dormer creates a dead valley. We also watch for condensation in attics that were never vented for a metal skin—summer humidity in Delaware County will sweat the underside if air cannot move. Hours are Mon–Fri 8am–6pm and Sat 9am–2pm from 3475 West Chester Pike, so measurements and material drops happen in daylight, not after dark on a wet Pike.
Code in this part of Pennsylvania still wants ice barrier at the eaves and proper flashing at masonry chimneys common on older Newtown Square stock. We do not pretend a metal roof is “maintenance-free”; fasteners at penetrations and sealant at pipe boots still need a look after a hard winter. If you have a historic-looking streetscape, we talk profile and color so the roof does not fight the house. What we will not do is glue standing seam over failing shingles or skip underlayment to hit a low number—those shortcuts show up the first time a nor’easter sits on the roof for two days.
Technician insight
In Newtown Square the thing that catches most people out with standing seam is assuming the old asphalt deck is ready. Freeze-thaw and humid summers leave wet plywood at eaves and around stone chimneys on 1960s–80s houses; if you clip metal to that, you trap moisture. We open the eaves first, especially on streets that drain toward West Chester Pike, because ice dams here are not theoretical.
Edgemont ranch with a leaking valley
A ranch near Gradyville had a valley that dumped water into the kitchen after every freeze. We found rotten deck at the valley and undersized flashing from an old overlay. After tear-off, new plywood, ice membrane, and standing seam with a wider valley pan, the leak stopped through the next winter’s ice cycles.

How it works
- 1
On-Site Measure And Deck Check
We walk the roof in Newtown Square or Edgemont, measure planes and penetrations, and open a few shingles if needed to see deck condition before quoting.
- 2
Tear-Off Or Overlay Decision
Sound deck can sometimes stay; rotten plywood, wet insulation, or mixed sheathing comes off so standing seam sits on a dry, even surface.
- 3
: Ice Barrier, Underlayment, And Clips
Eave membrane, synthetic underlayment, and clip layout go down to the manufacturer’s pattern so panels can move with summer heat and winter cold.
- 4
Panel Hang, Trim, And Penetrations
Panels lock, ridges and valleys close, and boots and chimney flashing get sealed so Delaware County rain and snow have nowhere to sit.
- 5
Final Walk And Cleanup
We check seams, fasteners, and gutters, then haul debris so the yard on West Chester Pike or a Gradyville lot is left usable.
Pricing
Standing seam is a premium system; price tracks square footage, tear-off vs. overlay, pitch, and how many chimneys and valleys the roof has. We give an upfront range after we see the deck—not a phone number pulled from thin air.
