Our Specialty Roofing Services in Folcroft
EPDM Roofing
EPDM - the black rubber membrane you’ve seen on commercial buildings - is often the right call for Folcroft’s low-slope rear additions. Those flat-roofed kitchen and utility extensions tacked onto postwar twins were never meant to carry standard shingles. We install fully adhered and mechanically attached EPDM systems from authorized manufacturer lines, with seams welded for permanence. A typical EPDM installation on a Folcroft rear addition runs $4,200-$7,800, depending on whether the original deck needs replacement after sixty-plus years of trapped moisture.
Modified Bitumen
Modified bitumen gives Folcroft homeowners the durability of built-up roofing with faster, cleaner installation. On that twin on Clifton Avenue, our crew found the original deck had been over-shingled three times, trapping moisture between layers. The neighbor reported interior ceiling stains, but the leak source was the shared valley flashing - compromised on the other unit’s side. We coordinated with both owners and installed a modified bitumen system on the low-slope rear addition while replacing decking on the main slope with GAF shingles. Modified bitumen runs $3,800-$6,500 for typical Folcroft additions.
Built-Up Roofing
For larger flat surfaces or homeowners who want the traditional multi-ply system, built-up roofing (BUR) remains a sound choice in Folcroft. The alternating layers of bitumen and reinforcing fabric create a monolithic surface that handles foot traffic during maintenance and resists the ponding that plagues poorly drained rear additions. BUR installation in Folcroft typically ranges $5,500-$9,200. We evaluate each structure’s load capacity carefully - original joists in 1950s construction weren’t always sized for the weight of modern roofing systems.
Solar Ready Roofing
Folcroft homeowners adding solar panels need decking that can handle both the load and the penetrations. With original decks now 65-80 years old, we often find that “solar ready” first means “deck ready.” Our inspections identify whether your twin’s shared structure can support panel arrays, and we coordinate with solar installers to ensure flashing details don’t compromise the neighbor’s side. Solar-ready prep and decking replacement in Folcroft runs $2,800-$5,400 before panel installation.
TPO Roofing
TPO’s white reflective surface cuts cooling costs for Folcroft’s flat-roofed commercial properties and some larger residential additions. The heat-welded seams hold up against southeastern Pennsylvania’s summer humidity and winter freeze-thaw punishment. TPO installation in Folcroft typically runs $4,500-$8,200.

We don’t make you wait for a special order from three counties away.
Common Specialty Roofing Problems We See in Folcroft Homes
- Shared flashing failures on twins. The valley or ridge flashing between semi-detached units is statistically the first point of failure in Folcroft. Water migrates laterally through the deteriorated deck and surfaces on the interior wall of whichever home sits downslope. The homeowner who calls us is often not the one whose roof is actively leaking.
- Original decks finally exhausted after 65-80 years. Folcroft’s postwar twins were built with roof decking that has never been replaced, only covered with successive shingle layers. The wood is often too rotted to support new shingles, but this isn’t visible until tear-off begins.
- Low-slope rear additions mismatched with standard shingles. Those flat kitchen and utility additions need EPDM or modified bitumen, not three-tab shingles installed against manufacturer specifications. The ponding and premature failure are predictable.
- Freeze-thaw flashing fatigue. Southeastern Pennsylvania’s 10-20 annual freeze-thaw events attack the low-to-moderate pitches common in Folcroft. Ice dams lift flashing edges, and summer humidity accelerates granule loss on aging asphalt.

FAQs - Specialty Roofing in Folcroft
You are likely not responsible for the cost, but you may need to grant access for the repair to be completed. On Folcroft’s semi-detached twins, water migrates laterally through shared decking and exits in the downslope unit, so the active leak appears in your home while the source is your neighbor’s side of the flashing. We routinely coordinate these repairs, document the actual penetration point with photos, and work with both owners to scope responsibility. Call (855) 554-5116 - we have handled dozens of these in Folcroft and can walk you through it.
No - and doing so would likely violate building code and void manufacturer warranties. Folcroft’s original roof decks have endured 65-80 years without replacement; the wood is often too deteriorated to support additional weight or properly nail new shingles. We find trapped moisture, rot, and compromised structural integrity on nearly every twin we inspect. The honest assessment is usually full deck replacement before any new roofing system goes on. We will show you the photos and explain exactly what we found.
Shingling a low-slope surface is a mismatch that causes predictable failure. Folcroft’s rear additions, typically added in the 1950s-1960s, have pitches below the minimum for asphalt shingles. Water moves too slowly to shed, leading to ponding, granule loss, and premature deterioration. EPDM or modified bitumen is the correct system for these surfaces. We have replaced too many failed shingle installations on Folcroft additions to recommend anything else.
The Philadelphia metro’s 10-20 annual freeze-thaw events drive ice dam formation and accelerate flashing fatigue on Folcroft’s low-to-moderate pitches. Water seeps into microscopic gaps, freezes and expands, then thaws and seeps deeper. This cycle lifts flashing edges, separates shingle tabs, and degrades the sealants that keep your roof watertight. Summer humidity compounds the damage by accelerating granule loss on already-aged asphalt. Proper ventilation, intact flashing, and appropriate membrane selection for each roof plane are your defenses.
The shared valley or ridge flashing between units fails first, statistically. Because the original decks are deteriorated and water migrates laterally, the active leak almost always surfaces on the interior wall of whichever unit sits downslope. Homeowners call us convinced their own roof is the problem, but the penetration point is typically their neighbor’s side of the flashing. This is why our Folcroft inspections always include both units when twins are involved. Call (855) 554-5116 - we will sort out where the water is actually coming from.
