We’ve built our reputation in Gloucester City one honest job at a time. Homeowners here know the difference between a contractor who’ll be gone by next spring and one who’s been standing behind local roofs for over 42 years. We’re the latter.
Our Gloucester City customers tell us they appreciate that we don’t quote low and invoice high. The price we quote is the price you pay.

Because Gloucester City sits just across the Delaware from our Philadelphia base, response time is fast.

Our Specialty Roofing Services in Gloucester City
Built-Up Roofing
Built-up roofing, or BUR, is what you’ll find under the patches on many Gloucester City row homes built between the 1890s and 1940s. These multi-ply systems of bitumen and reinforcing fabrics were the standard for flat roofs a century ago, and they’re still viable when properly maintained. In Gloucester City, we often encounter BUR that’s been layered over multiple times - each repair adding weight and hiding the true condition of the substrate. We strip to sound decking, rebuild where necessary, and install new built-up systems with proper drainage to address the ponding that plagues century-old flat roofs near the river.
TPO Roofing
TPO - thermoplastic polyolefin - has become our go-to recommendation for many Gloucester City flat-roof replacements. The white reflective surface handles the thermal cycling that cracks darker membranes, and the heat-welded seams stand up to wind-driven rain off the Delaware better than taped or glued alternatives. We install TPO from GAF and CertainTeed, authorized lines with full manufacturer backing. For the row home on Monmouth Street we mentioned, TPO with reinforced flashings and tapered insulation solved a ponding problem that had damaged two adjacent units through shared masonry walls.
Modified Bitumen
Modified bitumen bridges the gap between traditional BUR and single-ply membranes. It’s tough, flexible, and particularly well-suited to Gloucester City’s low-slope roofs where foot traffic during maintenance is common. APP-modified sheets handle high-temperature applications; SBS-modified sheets flex better in cold weather. Given Gloucester City’s freeze-thaw cycles along the waterfront, we often specify SBS-modified systems for river-facing properties. The material can be torch-applied, cold-adhered, or self-adhered depending on access constraints - important when you’re working on a tight row-home block with alley loading only.
EPDM Roofing
EPDM rubber roofing remains a solid choice for larger flat surfaces on Gloucester City’s commercial buildings and some residential applications. The black membrane absorbs heat, which can be advantageous in winter but requires careful specification in summer-exposed conditions. We install EPDM from authorized manufacturer lines with proper seam detailing and flashing integration - critical on older structures where parapet walls have shifted over decades.
Solar Ready Roofing
More Gloucester City homeowners are asking about solar readiness, even on flat roofs that once seemed unsuitable. Solar ready roofing means installing membranes and attachment points that can accept racking systems without compromising waterproofing. On row homes with limited roof area, every square foot matters. We coordinate membrane selection with future solar plans, using products from Owens Corning and other authorized lines that maintain warranty coverage after panel installation.
Green Roof Systems
Green roofs - vegetated assemblies - are rare in Gloucester City’s dense row-home environment but increasingly specified for commercial and institutional buildings. The added load requires structural verification, and drainage design must account for the saturated weight of growing media. We’ve installed green roof assemblies that manage stormwater on site, reducing the burden on Gloucester City’s century-old combined sewer infrastructure.

Common Specialty Roofing Problems We See in Gloucester City Homes
- Parapet wall flashing failure allows lateral water migration. In Gloucester City’s tightly packed row-home blocks, a failing parapet or chimney flashing on one unit routinely allows water to migrate laterally through shared masonry walls into adjacent homes. A roofer who diagnoses only the presenting unit will miss the true water entry point, and homeowners two doors down may be filing damage claims without knowing their neighbor’s parapet is the source.
- Wind-driven rain off the Delaware accelerates membrane degradation. Sitting directly on the riverfront, Gloucester City rooftops face persistent wind-driven moisture that hits exposed parapet copings and flashing with particular force. Nor’easters funnel up the Delaware Valley and strike riverside blocks harder than inland areas, cracking built-up surfaces and loosening gravel surfacing.
- Ponding water from century-old drainage systems. The original internal drains and scuppers on Gloucester City’s pre-WWII flat roofs were sized for different rainfall patterns and have often been partially blocked by decades of debris. Standing water adds structural load and accelerates membrane breakdown, particularly at seams and penetrations.
- Layered, non-uniform substrates from multiple generations of repair. Many Gloucester City flat roofs have cycled through three or four roofing campaigns - each new layer adding weight, each partial repair creating elevation changes that trap water. Stripping to a clean substrate is often the only way to achieve proper drainage.

FAQs - Specialty Roofing in Gloucester City
Leaks after heavy rain usually trace to parapet flashing failure or internal drain overflow, not the membrane itself. In Gloucester City, wind-driven rain off the Delaware hits parapet walls harder than inland locations, and century-old drains handle less volume than modern storms deliver. Water then finds the path of least resistance - often through shared brick party walls into adjacent units. If your row home leaks after rain, we inspect the parapet and neighboring conditions, not just your ceiling. Call (855) 554-5116 for a free inspection.
An overlay is possible when the existing roof has one layer, sound decking, and no chronic ponding. In Gloucester City, we rarely recommend overlays because most flat roofs here carry multiple previous layers and uneven substrates that trap water. A full tear-off lets us correct drainage, inspect decking, and install tapered insulation where needed. We’ll tell you honestly which path makes sense for your specific roof. Call for a free assessment.
Riverfront exposure shortens membrane life by 15-25% compared to inland locations. Wind-driven moisture, higher humidity, and accelerated freeze-thaw cycling at the parapet all contribute. In Gloucester City specifically, we specify membranes and flashings rated for marine exposure, and we pay particular attention to parapet copings and counterflashing details that inland contractors might treat as standard. The right material selection matters here more than almost anywhere else in Camden County.
Physically, yes. Practically, often no. Because water migrates laterally through shared brick party walls, repairing only your section can leave the true source unaddressed. We recently performed a modified bitumen overlay on a low-slope roof on Monmouth Street, where wind-driven moisture off the Delaware had ponded against a deteriorated parapet coping, forcing water through the brick into the neighbor’s attic. After stripping the original built-up roof, we installed a new TPO membrane with reinforced flashings and a tapered insulation system to eliminate ponding and protect both row homes. We coordinate with adjacent owners when possible, and we document lateral migration paths so everyone understands the full scope. Call (855) 554-5116 to discuss your specific situation.
For most Gloucester City flat roofs, we recommend TPO or modified bitumen over built-up roofing. TPO’s reflective surface handles thermal stress well; modified bitumen offers toughness in tight-access applications. The best choice depends on your roof’s slope, structural capacity, exposure to the river, and whether you plan to add solar. We don’t sell one product for every job. Our Specialty Roofing team evaluates your specific conditions and recommends accordingly. Free estimates: (855) 554-5116.
