Why Ridgeline Roofing Co. of New York City Is Fordham’s Preferred Specialty Roofing Company
Fordham isn’t a suburban market with pitched shingles and dormers. It’s four-to-six-story brick buildings with flat roofs, masonry parapets, and rooftop bulkheads that have been baking and freezing since the Hoover administration. We’ve been here long enough to see three generations of the same families own these buildings. That matters.
Our Specialty Roofing in Fordham work draws on over 42 years of standing behind local roofs, not chasing storms. When a Fordham property owner calls, they get a live person on the line, day or night, weekend or holiday. Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not the sidewalk below. We show you what we see.
We recently handled a Roof Replacement & Installation - Fordham project: a 5,000 sq ft flat roof on a six-unit walk-up on Creston Avenue, stripping deteriorating built-up tar-and-gravel and replacing it with a GAF modified-bitumen system, while also repairing failing mortar joints in the parapet coping to meet FISP requirements. That’s the kind of job we do in Fordham. Not theoretical. Not copied from a manual. Your building, your roof, your paperwork handled right.
Our 90-Day Done Right Promise applies to every job: if it’s not right, we come back and make it right. No forms to fill out, no arguments, no runaround. The price we quote is the price you pay. A square deal, plain and simple.
Our Specialty Roofing Services in Fordham
Built-Up Roofing (BUR)
Built-up roofing is what you’ll find under the gravel on most Fordham tenements from the 1920s through the 1950s: multiple layers of asphalt-impregnated felt, hot-mopped together, finished with a flood coat and gravel surfacing. When it’s intact, it’s durable. When it’s aged past 25 or 30 years, the asphalt embrittles, the felts separate, and blisters form that trap water. In Fordham’s climate, with dozens of freeze-thaw cycles each winter, those blisters crack open and leak. A full BUR replacement on a typical Fordham walk-up runs $12,000-$22,000. Spot repairs on isolated blisters or splits start around $1,200. We evaluate whether the existing layers can be salvaged or if a complete tear-off is the honest call.
Modified Bitumen
Modified bitumen is the modern successor to traditional BUR, and it’s what we often recommend for Fordham buildings where the old system has failed but the deck is sound. APP-modified membranes handle the thermal expansion of dark flat roofs in summer better than old-style BUR, and torch-applied or self-adhered installation gives reliable seams. We recently re-membraned a 5,000 sq ft flat roof on a six-unit walk-up on Creston Avenue, stripping deteriorating built-up tar-and-gravel and replacing it with a GAF modified-bitumen system, while also repairing failing mortar joints in the parapet coping to meet FISP requirements. A typical modified bitumen installation on a Fordham tenement runs $10,000-$18,000 for the membrane field, with parapet coping and flashing work adding $3,500-$8,000 depending on linear footage and access.
TPO Roofing
TPO single-ply membrane has become popular for Fordham buildings where energy efficiency and reflective roofing matter. The white surface reduces cooling loads in summer, which matters on a flat roof that takes full sun all day. TPO also welds cleanly at seams, creating a monolithic barrier that’s excellent around rooftop bulkheads and mechanical curbs where older buildings often leak. Installation costs for TPO on a typical Fordham walk-up range from $11,000-$20,000. Critical detail: TPO requires precise welding and proper flashing at all penetrations. We’ve seen too many leaks caused by rushed seam work or inadequate curb details. Our Specialty Roofing technicians are manufacturer-trained on TPO installation.
EPDM Roofing
EPDM rubber membrane has been the workhorse of commercial flat roofing for decades, and it performs well on Fordham’s low-slope buildings. The black membrane absorbs heat, which can be an advantage in winter but requires careful insulation detail. EPDM is particularly forgiving of building movement and settling, which matters in 90-year-old brick structures. Ballasted EPDM systems use stone to hold the membrane, while fully-adhered systems glue it down for wind uplift resistance. A typical EPDM installation on a Fordham tenement runs $9,500-$17,000. We often specify EPDM for buildings with significant structural movement or where the existing roof has irregular contours that would stress a more rigid membrane.
Solar Ready Roofing
Fordham’s flat roofs are increasingly being evaluated for solar panel installation, but solar on a pre-war tenement requires a roof system designed for the load and the penetrations. Solar ready roofing means we install a membrane and flashing system that anticipates racking attachments, conduit penetrations, and the 25-year service life that solar financing requires. Retrofitting solar onto an aging BUR roof is a mistake we’ve seen too many times: the panels get installed, the roof leaks within five years, and now you’re removing solar to fix the membrane underneath. We design the roof system first, solar second. Solar ready roofing installations in Fordham typically run $13,000-$24,000, depending on structural evaluation and electrical coordination.
Green Roof Systems
Green roofs, intensive and extensive, are still uncommon in Fordham but growing as NYC promotes stormwater management and urban heat island reduction. The load requirements are substantial, typically 15-25 pounds per square foot for extensive systems and 80+ for intensive planted roofs. Most Fordham tenements require structural engineering evaluation before green roof installation. We coordinate with registered architects and structural engineers for the permitting. Where structurally feasible, green roofs extend membrane life by protecting it from UV and thermal cycling. Expect $25,000-$45,000 for a basic extensive green roof on a typical Fordham building, including structural review, growing medium, and plant establishment.

Trusted Brands We Service in Fordham
We install authorized systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Fordham’s flat-roof market, we most often specify GAF and CertainTeed modified-bitumen and TPO systems, with IKO and Atlas membranes where specific building conditions warrant. We maintain relationships with local distributors in the Bronx to ensure materials are available without the delays that can strand a building with an open roof. No substitutions without your approval. The brand on the estimate is the brand on your roof. We stock common flashing components and membrane widths for Fordham building footprints, which means faster turnaround from contract to completion. Most jobs are done in a single mobilization.
Common Specialty Roofing Problems We See in Fordham Homes
- Aging built-up tar-and-gravel membranes develop cracks and blisters from freeze-thaw cycles, allowing water to pool and infiltrate. The asphalt in old BUR systems oxidizes and becomes brittle over decades. When winter temperatures swing from 20°F to 50°F and back, trapped moisture expands and contracts, turning hairline cracks into splits that leak directly onto plaster ceilings below. We see this on nearly every pre-war building in Fordham that hasn’t had a roof replacement in 25+ years.
- Deteriorated parapet coping mortar joints and open roof-to-parapet junctions are common entry points for moisture, especially after dozens of winter freeze-thaw cycles. The parapet wall is the most vulnerable part of a Fordham flat roof. Coping stones shift, mortar falls out, and the junction between roof membrane and parapet wall opens up. Water runs behind the membrane, down the wall, and appears as stains on top-floor ceilings far from where you’d expect. NYC’s Local Law 11/FISP mandates parapet inspection precisely because this failure mode is so common and so dangerous.
- Rooftop bulkheads and mechanical curbs on older buildings often have compromised flashings that leak, requiring specialized TPO or EPDM flashing details. Every tenement has bulkheads for stair access, elevator machinery, or HVAC equipment. The metal flashings around these penetrations fatigue, the sealant dries out, and the resulting leaks can damage multiple floors before they’re traced to the source. Proper detail work with prefabricated TPO or EPDM pipe boots and custom-fabricated metal counterflashing solves this for the long term.
- Ponding water on low-slope surfaces accelerates membrane degradation and creates structural loading concerns on older roof decks. Fordham’s flat roofs rarely have perfect drainage after 80+ years of settlement and modification. Water that stands for more than 48 hours breeds algae, accelerates UV degradation, and adds dead load to joists that may already be at capacity. We evaluate drainage paths as part of every inspection and specify tapered insulation or crickets where re-roofing allows correction.

FAQs - Specialty Roofing in Fordham
Yes, virtually all flat roof replacements on Fordham’s multi-family buildings require a NYC Department of Buildings permit, and parapet work often requires filing with a registered architect or professional engineer under Local Law 11/FISP mandates. We handle the permit application, filing, and inspection scheduling as part of our project management. Call (866) 756-1978 and we’ll review your building’s specific requirements during our free estimate.
Fordham experiences dozens of freeze-thaw cycles each winter, and water that pools on low-slope surfaces infiltrates cracked coping stones and open parapet-to-roof junctions, then expands and widens those failures with each freeze. The roof perimeter and parapet become the most common source of interior water damage in this housing stock. We design our repairs and replacements to address this specific failure mode with proper drainage, durable membranes, and sealed parapet details.
Repair makes sense when less than 25% of the field area is compromised and the underlying insulation is dry; replacement is the honest call when blistering is widespread, the asphalt is oxidized and cracking, or there are multiple leak points indicating systemic failure. Our Roof Repair in Fordham team will show you photos of your actual roof and give you a straight recommendation. A typical Fordham walk-up BUR repair runs $1,200-$4,500, while full replacement is $12,000-$22,000. We’ll show you photos of your actual roof and give you a straight recommendation.
