We’ve been climbing Collingdale roofs since 2016. Our crews know the borough’s tight streets, the 14-foot lot widths on MacDade Boulevard, and the particular headache of staging scaffolding between attached twins without damaging your neighbor’s gutters. Collingdale’s housing stock is unlike anywhere else in Delaware County: front-facing slate pitches built in the 1920s and 1930s, paired with rear flat roofs that were added or modified decades later. That dual-roof reality means a contractor who only knows shingles will miss the real problem. We handle both. Our Specialty Roofing team trains on slate restoration, modified bitumen, EPDM, and built-up systems - the full mix Collingdale demands.

Our Specialty Roofing Services in Collingdale
Modified Bitumen Roofing
Modified bitumen is our most common repair on Collingdale’s rear flat roofs. The freeze-thaw cycle here is brutal: water pools on the low-slope section, freezes overnight, and splits the membrane at seams and penetrations. A typical modified bitumen repair in Collingdale runs $1,400-$2,800 for a partial recover, or $3,200-$5,500 for a full tear-off and replacement on a standard twin-home rear section. We install GAF Liberty SBS mod bit with proper drainage corrections - critical on lots where the downspout was routed incorrectly decades ago and nobody noticed until the ceiling stained.
We recently repaired a modified-bitumen rear roof on a twin home on Maple Avenue where standing water from a clogged drain had frozen and split the membrane. The front slate was still sound, so we patched the flat section with GAF Liberty SBS mod bit, ensuring a watertight transition at the eave to prevent future ice dam damage.
Built-Up Roofing (BUR)
Built-up roofing still protects many of Collingdale’s older commercial buildings and some residential rear additions. When the gravel surfacing washes off or the felts dry out, leaks can spread across multiple rooms before they’re detected. BUR restoration in Collingdale typically costs $2,000-$4,500 for spot repairs and re-graveling, or $5,500-$9,000 for a complete four-ply system replacement. We assess whether the existing substrate can be saved - often it can on these older structures - rather than defaulting to full removal.
EPDM Roofing
EPDM rubber membrane works well on Collingdale’s low-slope sections where weight is a concern or where the structure can’t handle built-up roofing’s heavier load. A single-ply EPDM installation on a typical row-home rear roof runs $2,800-$5,000, including proper insulation board and mechanical fastening. We favor ballasted or fully-adhered systems over ballasted on tight Collingdale lots where wind uplift is a real risk between buildings.
Solar Ready Roofing
Collingdale homeowners adding solar panels face a particular challenge: the front slate may need structural evaluation before racking installation, while the rear flat roof requires a membrane that won’t degrade under panel heat loads. Our solar-ready prep includes deck reinforcement assessment, proper flashing for panel penetrations, and membrane selection rated for elevated temperatures. Solar-ready roofing prep in Collingdale ranges from $1,800-$4,500 depending on existing conditions and panel layout.

Trusted Brands We Service in Collingdale
We stock materials from CertainTeed, Owens Corning, and IKO for Collingdale jobs, with most common membrane rolls, flashing details, and slate repair pieces available within 24 hours through our Philadelphia supply chain. That matters on Collingdale’s narrow blocks where a delayed delivery means rescheduling crane or lift access that affects three neighboring properties. We’re also authorized installers for GAF, Atlas, Tamko, and Boral - seven manufacturer lines total - so we match the right material to your roof rather than selling whatever’s in the warehouse. No substitutions without your written approval. The price we quote is the price you pay.
Common Specialty Roofing Problems We See in Collingdale Homes
- Ice damming at the slate-to-flat transition. The eave where your pitched front slate meets the lower rear flat roof is a chronic failure point. Melting snow runs down the slate, refreezes at the cold eave, and backs water under both the slate edges and the flat membrane. We see this repeatedly on MacDade Boulevard and Clinton Avenue twins.
- Freeze-thaw blistering on flat rear roofs. Poor drainage plus Collingdale’s winter temperature swings splits modified-bitumen and built-up membranes from underneath. Blisters that look cosmetic in September are leaks by February.
- Narrow-lot damage during neighboring work. With lot widths of 14-18 feet, ladder placement and debris removal on one property often damages adjacent roofs or gutters. We protect neighboring structures as standard practice, not an add-on.
- Mismatched roof life cycles. In Collingdale, the front slate pitch often retains 10-20 years of service life while the rear flat roof fails from freeze-thaw cycles, forcing homeowners to decide between mismatched timing for repairs or a full replacement across both roof types. There’s no universal right answer - we assess each case honestly and explain both paths.

FAQs - Specialty Roofing in Collingdale
Yes. We regularly repair rear flat roofs on Collingdale twins and row homes while leaving sound front slate untouched. The key is properly flashing the transition at the eave so water doesn’t migrate between systems. We use compatible membrane materials and detail the joint to prevent the ice damming that commonly fails at this intersection. Call (855) 554-5116 for a free assessment - we’ll photograph both roofs and show you exactly what needs attention now and what can wait.
Look for missing or sliding slates, daylight visible from the attic, and rust-colored staining on interior ceilings - these indicate active leaks. If the slate itself is sound but fasteners are failing, we can re-fasten and replace individual slates for $1,800-$4,200. Full replacement becomes necessary when the slate is delaminating (flaking apart), when more than 20% of fasteners are corroded, or when the underlying decking is compromised. We document everything with photos during our inspection and give you an honest timeline for both options.
No. Standing water that remains more than 48 hours after rain indicates improper drainage or structural sagging. On Collingdale’s older flat roofs, clogged drains, failed crickets, or settled substrate are common culprits. Pooling accelerates freeze-thaw damage and will destroy any membrane prematurely. We correct drainage as part of every flat-roof repair or replacement - it’s not optional, and it’s included in our estimate. Call (855) 554-5116 before the next hard freeze.
Yes. This transition is one of the most technically demanding details in Collingdale roofing, and it’s where less experienced contractors often fail. We rebuild the step flashing, install ice-and-water shield appropriate to the slope change, and ensure the flat membrane terminates properly under the slate eave. Done wrong, this joint leaks within two winters. Done right, it lasts the life of both roof systems. We’ve refined our detail through four decades of working on Delaware County’s streetcar suburbs.
We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral products, selecting the specific membrane or system based on your roof’s slope, structure, and exposure. For Collingdale’s flat rear roofs, we commonly use GAF Liberty SBS modified bitumen or Carlisle EPDM, depending on drainage conditions and whether the structure can handle the weight. We never substitute materials without your approval - the brand and product specified in your estimate is what goes on your roof.
