Why Ridgeline Roofing Co. of New York City Is Gravesend’s Preferred Roof Replacement & Installation Company
We’ve been working on Gravesend roofs since 2016. That’s over 42 years of learning how the salt air off Coney Island eats metal, how the 1940s-1960s brick row houses settle at their party walls, and how a nor’easter can drive rain straight through a cracked coping. Sal Benedetto founded this company on the idea that a roof should be done right, and if it isn’t, you shouldn’t have to fight to get it fixed.
Our 90-Day Done Right Promise means exactly that: if something isn’t right, we come back and make it right. No forms to mail in, no voicemail trees, no arguing. We answer our phones live, 24/7, because a roof leaking at 2 a.m. doesn’t care about business hours. Our technicians are background-checked, uniformed, and they photograph every inspection from your actual roof - not the sidewalk, not the driveway. You see what we see.
We hire local crews and train apprentices into journeymen. We’re not storm chasers who blow into town after a hurricane and vanish. We’re the company that plans to be fixing Gravesend roofs in thirty years. That’s why homeowners near McDonald Avenue and Shore Parkway call us back, and why they send their neighbors.
Our Roof Replacement & Installation Services in Gravesend
Full Roof Replacement
Most Gravesend homes need full roof replacement not because of one big failure, but because every component of a 60-year-old flat system has reached end of life together. The original coal-tar or early modified bitumen membrane is brittle. The parapet coping stones have shifted. The interior drains are half-clogged with tar gravel and roof cement from decades of patch jobs. We strip to the deck, assess for rot (common around drains and parapets), and install a complete system: new insulation if needed, current-code membrane, proper flashing, and drainage that actually moves water off the roof. On Avenue U we replaced a failing modified bitumen roof on a 1950s two-family brick row house. The old coping stones had shifted where adjacent structures settled differently, cracking the counterflashing. We used GAF modified bitumen, replaced the coping with prefinished metal, and installed stainless steel counterflashing to seal the party-wall junction.

Flat Roofing
Flat roofing is what Gravesend is built on. The neighborhood’s two- and three-story attached brick row houses, almost all put up between 1945 and 1970, were designed with low-slope roofs and parapet walls. We install modified bitumen systems (torch-applied or self-adhering) and, where appropriate, built-up roofing with reflective cap sheets. The critical detail on every Gravesend flat roof is the parapet-to-party-wall junction. This is where adjoining buildings settle at different rates, cracking the counterflashing and letting wind-driven rain in. Homeowners often blame their windows or the brickwork. It’s usually the roof. We address this with flexible membrane transitions, stainless steel counterflashing, and proper coping that allows for movement without breaking the seal.

Asphalt Shingles
While most Gravesend homes are flat-roofed, we do see asphalt shingle work on detached homes near the edges of the neighborhood, on additions, and on porches and bulkheads. For these, we install architectural shingles from Atlas and Tamko with proper ice-and-water shield at eaves and valleys. Even on pitched surfaces here, the salt air matters - we use corrosion-resistant fasteners and flashing that won’t turn to powder in five years.

Metal Roofing
Metal roofing on Gravesend’s flat row houses is generally limited to specific applications: standing seam on small additions, porch roofs, or as a replacement for failed coping caps on parapet walls. We do not install pitched metal roofs on structures designed for flat loading. Where metal makes sense, we specify aluminum or coated steel with salt-air-rated finishes, never bare galvanized that will white-rust within a season this close to the ocean. Boral and IKO both make accessories we use for these detail applications.

Tile Roofing
Clay and concrete tile is rare in Gravesend’s housing stock, but we handle it on the occasional Spanish-style home or on commercial properties near Kings Highway. Weight is the main concern - many of these older structures need structural assessment before tile goes on. We work with an engineer when needed and install only manufacturer-specified underlayment and fastening systems.

New Construction
For new builds and major renovations in Gravesend, we design roof systems that account for the coastal environment from day one. That means proper drainage schematics (interior drains with overflow provisions, not just scuppers), parapet details that won’t leak in a nor’easter, and material specifications that resist salt corrosion. We coordinate with your general contractor and file permits with the NYC Department of Buildings, which we know from decades of work in Brooklyn Community Board 15.

Trusted Brands We Service in Gravesend
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Gravesend’s flat-roof market, we most often specify GAF and CertainTeed modified bitumen systems, with IKO and Atlas cap sheets where reflective or walkable surfaces are needed. We stock common membrane widths, flashing details, and drain components locally, so most Gravesend jobs aren’t delayed waiting on materials. When we specify stainless steel hardware for coastal exposure - counterflashing, coping fasteners, drain clamps - we source from suppliers who certify their alloy content, not the cheapest import that will pit in two seasons.
Common Roof Replacement & Installation Problems We See in Gravesend Homes
- Salt corrosion of metal components. The Atlantic Ocean is barely a mile away. Salt-laden air corrodes metal flashing, lead boots, fasteners, and exposed aluminum on Gravesend flat roofs within 5-7 years, far faster than in interior Brooklyn neighborhoods. We see premature leaks at parapet walls and drains where standard galvanized hardware has turned to rust dust.
- Clogged interior drains and ponding water. These 1940s-1960s row houses have interior drains that collect decades of tar gravel, roof cement, and debris. Freeze-thaw cycles stress the clogged system; ponding water accelerates membrane failure, especially on older modified bitumen that has lost its granule protection.
- Failed parapet-to-party-wall junctions. Roofers in Gravesend know that the junction on attached brick row houses along streets like Avenue U and Kings Highway is the single most common leak point. Adjoining structures settle at slightly different rates, cracking the flashing counterflashing detail. Homeowners often blame windows or masonry rather than calling a roofer until interior damage is extensive.
- Aged coping stones and open parapets. The original precast concrete coping stones on these postwar row houses have shifted, cracked, or lost their mortar beds. Wind-driven rain from coastal storms enters behind the coping and runs down the interior of parapet walls, showing up as stains on top-floor ceilings.

FAQs - Roof Replacement & Installation in Gravesend
A properly installed modified bitumen flat roof on a Gravesend row house typically lasts 15-20 years, but many original roofs from the 1940s-1960s are still in place and well past their useful life. If your roof is over 25 years old, has been patched more than twice, or shows interior stains after every heavy rain, it’s time to plan for replacement. Call (866) 756-1978 for a free inspection and honest assessment - we photograph what we find so you can see it yourself.
Yes. On every Gravesend job within a mile of the shore, we specify stainless steel counterflashing, coping fasteners, and drain hardware. Standard galvanized steel corrodes in 5-7 years in this salt air; stainless lasts the life of the membrane. We don’t charge extra for this. It’s simply how we build roofs that hold up here.
Differential settlement. Adjoining row houses in Gravesend settle at slightly different rates over decades, cracking the counterflashing where the roof meets the party wall. Wind-driven rain from coastal storms enters these cracks and runs down interior walls. Homeowners often mistake this for a window leak or masonry problem. We fix it with flexible membrane transitions and stainless steel counterflashing designed to accommodate movement. If you’re seeing stains on a shared wall, call us - the fix is roofing, not pointing.
For most Gravesend row houses, we recommend modified bitumen. It’s lighter than built-up roofing (important on these older structures), faster to install, and performs better at the detail work - parapets, drains, penetrations - that dominate Gravesend roofing. Built-up roofing has its place on commercial decks and heavy-traffic roofs, but for residential flat roofs in this neighborhood, modified bitumen with proper base and cap sheets gives better value and fewer leak points. We install both, and we’ll tell you honestly which suits your specific roof.
Not as a primary roof system. These houses were engineered for flat loading, and a pitched metal roof would require structural modifications that rarely make sense. Where metal works well in Gravesend is on parapet coping caps, small porch roofs, and additions. We use coated aluminum or salt-air-rated steel, never bare galvanized. If you’re considering metal for a specific application, call (866) 756-1978 and we’ll assess whether it’s appropriate for your structure.
