Fast, Reliable Specialty Roofing Across Glenolden
Specialty roofing in Glenolden typically costs $4,200-$12,800 depending on the system, and most flat-roof repairs on rear additions are completed in a single day. We answer live at (855) 554-5116, with crews usually on-site in Glenolden within two hours for urgent leaks.
We’ve been working on Glenolden roofs since 2016, and we know the borough’s housing stock inside out. The 19036 zip is built almost wall-to-wall with mid-century brick row homes and twins from the 1940s and 1950s. Nearly every one of these properties carries two completely different roofing systems: a sloped asphalt-shingle main roof up front, and a flat or low-slope rear addition covering the kitchen, utility area, or back porch. That junction where the two meet is where the trouble lives. A roofer who only knows shingles or only knows flat roofs will miss it. Our Specialty Roofing crew handles both on the same call, because in Glenolden, you can’t do one without the other.
Access is tight here. Narrow alley setbacks behind row homes on streets like Oak Avenue and Ashland Avenue mean our trucks need to know the block before they arrive. We coordinate with homeowners about parking, alley clearances, and shared driveway schedules. We don’t block your neighbor in, and we don’t leave materials sitting in the street.

Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not from the driveway.

Our Specialty Roofing Services in Glenolden
EPDM Roofing
EPDM is our go-to membrane for Glenolden’s flat rear additions. The synthetic rubber holds up against the freeze-thaw punishment of southeastern Pennsylvania winters, flexing through temperature swings that crack lesser materials. On a recent job on Oak Avenue, we replaced the original coal-tar built-up flat roof on a rear addition with a new EPDM membrane and repaired the step flashing at the shared party wall where water had been seeping into a neighbor’s side. The homeowners had been patching the same leak for years without addressing the root cause at the junction. EPDM doesn’t require the open-flame installation of built-up systems, which matters in tight Glenolden alleys where fire safety is a real concern. A typical EPDM installation on a Glenolden rear addition runs $4,200-$7,800.

Built-Up Roofing
Built-up roofing, or BUR, is what you’ll find under the gravel on many original Glenolden flat roofs. Multiple layers of bitumen and reinforcing fabric create a thick, durable membrane that can last 20 years when properly maintained. We still install BUR for homeowners who want the traditional system their house was designed for, particularly on larger rear additions where the mass of the assembly provides useful thermal buffering. The trade-off is weight: older Glenolden row homes need their structure evaluated before we add a new BUR system. We handle that assessment in-house. BUR replacement in Glenolden typically ranges from $5,500-$9,400.

Modified Bitumen
Modified bitumen bridges the gap between old-school BUR and modern single-ply membranes. The APP or SBS modifiers give the asphalt base rubber-like flexibility, which is exactly what Glenolden’s freeze-thaw cycles demand. We torch-apply or cold-adhere modified bitumen depending on the job conditions, and we favor it for row homes where the rear addition roof sees heavy foot traffic from HVAC maintenance or satellite dish work. The granulated surface provides grip. Expect $4,800-$8,200 for modified bitumen on a standard Glenolden rear addition.

TPO Roofing
TPO’s white reflective surface cuts cooling costs for Glenolden homeowners whose flat rear additions bake in summer sun. The heat-welded seams create a monolithic membrane with no weak points, and TPO resists the chemical exposure from vented kitchen grease and utility exhaust common in dense row-home alleys. TPO installation in Glenolden runs $5,200-$9,800 for typical rear additions.

Solar Ready Roofing
Glenolden’s compact roof footprints and south-facing rear slopes make solar viable for homeowners planning to stay put. Our solar-ready installations reinforce the structural deck, run conduit paths, and install compatible flashing before panels ever arrive. This prevents the retrofitted penetrations that cause so many leak callbacks. Solar-ready prep on a Glenolden row home typically costs $2,800-$4,500 added to a roof replacement.

Green Roof
Intensive green roof systems are rare in Glenolden’s dense housing, but we’ve installed lightweight extensive systems on a few commercial and mixed-use properties near the borough center. These require structural engineering, proper drainage, and ongoing maintenance planning. Call for consultation if you’re considering this path.

When a nor’easter tears through Delaware County and your flat roof starts leaking, that local inventory matters.
Common Specialty Roofing Problems We See in Glenolden Homes
- Neglecting the unique two-system junction: Many roofers only handle sloped or flat roofs, leaving the vulnerable transition between the two unaddressed. In Glenolden, this junction is the dominant chronic leak source across the borough, and it requires a crew fluent in both shingle and membrane work.
- Using standard drip edge instead of proper counter-flashing at shared party walls: Glenolden’s row homes and twins share rooflines with adjoining structures. Without correct step flashing and counter-flashing, water migrates between homes, causing damage that neither neighbor can trace without a thorough inspection.
- Overlooking ponding water on flat rear additions due to clogged scuppers: Debris from narrow alley setbacks routinely blocks drain scuppers on Glenolden’s flat roofs. Water sits, accelerates membrane failure, and turns a maintenance call into a full replacement before homeowners realize the scope.
- Inadequate attic insulation creating ice-dam risk at low-pitched eaves: Glenolden’s freeze-thaw cycle from November through March means escaping heat hits the eaves, melts snow, and refreezes at gutters. This backs water under shingles and into the junction zone where sloped and flat systems meet.

FAQs - Specialty Roofing in Glenolden
The junction between the sloped shingle roof and the flat rear addition is the most common chronic leak source in Glenolden because two entirely different roofing systems expand, contract, and drain at different rates, and the original flashing at this transition was often inadequate or has deteriorated after 70-plus years. Southeastern Pennsylvania’s freeze-thaw cycle accelerates the failure. Our crew addresses both systems and the transition in a single scope of work, which is the only way to stop the leak permanently. Call (855) 554-5116 for a free inspection and estimate.
Yes, localized repairs are often possible if the membrane is generally sound and the leak is isolated to a seam, penetration, or small damaged area. We patch EPDM with cured-tape systems, heat-weld TPO seams, and apply modified bitumen patches where appropriate. However, if the original coal-tar built-up roof is past its service life or if ponding water has compromised large areas, replacement is the more economical long-term choice. We’ll show you photos from your actual roof and explain which path makes sense. Estimates are free - call (855) 554-5116.
We install proper counter-flashing that extends up the party wall and under the siding or coping, with step flashing woven into each course of shingles. This creates a waterproof barrier that prevents lateral water migration between adjoining structures. In Glenolden’s dense housing, we often need to coordinate access with neighbors, and we’re experienced at doing this respectfully and efficiently. The work is photo-documented for both property owners. Call (855) 554-5116 to discuss your specific situation.
EPDM and modified bitumen both perform well in Glenolden’s climate. EPDM’s synthetic rubber composition remains flexible at low temperatures, resisting the cracking that affects stiffer materials. Modified bitumen’s SBS or APP modifiers provide similar elasticity with the added durability of a reinforced asphalt base. TPO also works but requires proper installation to prevent seam stress from thermal movement. We recommend against cheap single-ply alternatives that aren’t rated for Philadelphia’s climate zone. For a specific recommendation based on your roof’s condition and your budget, call (855) 554-5116 for a free estimate.
No, ponding water that remains for more than 48 hours after rainfall indicates inadequate drainage, improper slope, or clogged scuppers, and it will accelerate membrane failure and eventually cause interior damage. In Glenolden, debris from narrow alley setbacks routinely blocks scuppers on older flat roofs, and the original coal-tar built-up systems may have settled or sagged over decades. We clear drains, evaluate slope, and recommend corrective work ranging from targeted repairs to full replacement with proper drainage design.
