We’ve been driving to Folcroft since 2016, back when the borough’s postwar housing stock was only twenty years old. Now those same roofs are pushing seventy and eighty, and we’re seeing the consequences: original decking that’s never been exposed, three layers of shingles pressing down on rafters never designed for the load, and flat rear additions that have been patched so many times the flashing looks like a quilt. Our Roof Replacement & Installation team knows these houses. We know where the ice dams form on the low pitches facing the Delaware River winds. We know which blocks in Folcroft still have the original one-by plank decking, and which have the later plywood upgrades. That knowledge matters when we’re giving you a number that won’t change.

Our Roof Replacement & Installation Services in Folcroft
Full Roof Replacement
Most Folcroft twins need full replacement, not another overlay. The original 1940s and 1950s roof decks - one-by planks or early plywood - have carried successive shingle layers for decades. The fasteners deteriorate. The sheer weight increases. During freeze-thaw cycles, the entire assembly can slide or buckle. We tear off to the deck, assess what’s salvageable, and replace what isn’t. On a recent job on Clifton Avenue, we replaced both sides of a shared low-slope rear addition on a 1949 twin where the original modified bitumen had delaminated. The neighbor’s unaddressed flashing gap had been sending water under our client’s siding for months. We coordinated a combined tear-off, installed EPDM on both sides, and tied in new GAF Timberline shingles on the main roof to create a unified, leak-proof system.

Asphalt Shingles
Asphalt shingles still dominate Folcroft for good reason: they’re cost-effective, they handle our climate when properly installed, and they’re the right weight for the borough’s older framing. We install CertainTeed, Owens Corning, and Atlas shingles - brands we’ve worked with long enough to know which lines perform best on the 4/12 to 6/12 pitches common here. A typical asphalt shingle replacement on a Folcroft twin runs $8,500-$14,000. We don’t substitute materials. What we specify is what arrives on the truck.

Flat Roofing
The rear additions on Folcroft’s twins - kitchens, bathrooms, utility rooms added in the 1960s and 1970s - are almost always flat or low-slope. Standard shingles can’t go there. We install EPDM rubber and modified bitumen systems, matching the expansion rates and flashing details to the main roof’s slope. This is where most “mystery leaks” originate: the transition between sloped and flat, where original pitch pans have corroded and counter-flashing has separated. We replace both systems together when possible. It’s the only way to guarantee the junction.

New Construction
New builds are rare in Folcroft, but they happen - additions, teardowns on the borough’s few detached lots, and the occasional infill project. We spec complete systems from the deck up, coordinated with your general contractor, and we pull our own permits. Same standards: photo documentation, written guarantee, live phone.

Common Roof Replacement & Installation Problems We See in Folcroft Homes
- Shared flashing failures between twins. The valley or ridge flashing between semi-detached units is statistically the first point of failure. Water migrates laterally through the deck, then surfaces on the interior wall of whichever unit sits downslope. The homeowner calling us is often not the one whose roof is actually leaking.
- Triple-layer shingle assemblies sliding on original decking. Many Folcroft roofs have been overlayed two or three times without ever exposing the deck. The fasteners corrode, the weight accumulates, and during freeze-thaw cycles the whole mass can shift. We’ve seen buckled ridges and sheared nails on Taylor Drive and Delmar Drive alike.
- Flat addition leaks at the slope transition. The rear additions on most Folcroft twins were roofed separately from the main house, with mismatched materials and expansion rates. The pitch-pan or counter-flashing corrodes, thermal movement opens gaps, and water enters where the two systems meet.
- Ice dam damage on low-pitch eaves. Folcroft’s river-facing exposures and moderate pitches collect snow that melts and refreezes at the gutter line. Southeastern Pennsylvania’s 10-20 annual freeze-thaw events drive repeated dam formation, lifting shingles and accelerating flashing fatigue.

FAQs - Roof Replacement & Installation in Folcroft
You probably need a coordinated repair or replacement of the shared flashing, not necessarily a full roof on your side alone. On Folcroft’s semi-detached twins, water enters at the upslope unit’s failed valley or ridge flashing, then travels laterally through the continuous deck before dropping into the downslope unit’s wall cavity. We’ve scoped this exact scenario on Taylor Drive and Delmar Drive. The fix requires accessing both sides, which means neighbor coordination. We handle that conversation, document both roofs, and propose a fair cost split. Call (855) 554-5116 - we’ll inspect both sides and give you a clear answer.
No. Philadelphia building code and manufacturer warranty requirements both prohibit more than two layers, and a third overlay is never advisable on Folcroft’s original-era framing. The rafters and decking were designed for one layer plus snow load, not three or four. We’ve removed triple-layer assemblies where the fasteners had corroded through and the bottom layer was sliding downhill. Full tear-off lets us inspect and replace the deck, properly flash the valleys, and install a system that will last. A typical full tear-off and replacement on a Folcroft twin runs $8,500-$14,000 for asphalt shingles. Estimates are free.
They don’t have to be, but replacing both together is the only way to guarantee the junction between them. The transition where your sloped main roof meets the flat rear addition is the most leak-prone point on most Folcroft twins. Original pitch pans corrode. Counter-flashing separates. The two systems expand and contract at different rates. If we replace only one side, we’re tying into old, fatigued material at that critical seam. When budget allows, we recommend a combined replacement with compatible systems - typically EPDM or modified bitumen on the flat, asphalt shingles on the slope, and new custom flashing at the transition. Call for pricing on your specific configuration.
Southeastern Pennsylvania experiences 10-20 freeze-thaw events each winter, and each cycle forces water into cracks, then expands that water as ice, widening the gap. On Folcroft’s low-to-moderate pitch roofs, snow melts from attic heat, runs to the cold eave, and refreezes into ice dams that lift shingles and back water up under the laps. Summer humidity then compounds granule loss on already-aged asphalt. A roof that might last twenty-five years in a stable climate often needs replacement at eighteen to twenty years here. We spec materials and installation details specifically for this cycle.
Not effectively. The continuous deck and integrated flashing between Folcroft’s twins means a partial fix leaves the original failure point intact and often redirects water into new paths. We’ve been called back to jobs where a homeowner paid for a “single-side” repair, only to have the leak reappear six months later in a different wall. We won’t do partial flashing replacements on shared twins - it’s not a repair that holds, and our 90-Day Done Right Promise means we stand behind the result. We offer to coordinate with your neighbor, document both sides, and propose a split cost. Most neighbors agree once they understand the shared risk. Call (855) 554-5116 and we’ll explain the process.
