Most of Our Calls Come From Roofs That Were Already “Fixed”
A patch over the stain doesn’t stop a leak that starts at the parapet, the flashing or a clogged drain. We trace the water back to where it actually gets in, fix that, and tell you straight whether a repair will hold or the roof has run its course.
A reputable Brooklyn roofing company since 1997, owned and run by John
John comes out, looks at the roof himself and explains what’s wrong in plain English. No job is too small or too big: one cracked seam, a full tear-off down to the boards, or the roof over a storefront.

Residential and commercial roofing for Brooklyn and nearby parts of Queens, Staten Island and Manhattan. Here’s what each service covers and when you need it.
What we do
Roof Repair
Flashing pulling off a parapet, an open seam, a clogged drain or a cracked pitch pocket. We find which one it is and fix it with the right material. Roof repair in Brooklyn →
Roof Replacement
When a roof has been patched and coated too many times, or already has two layers, we tear off to the deck, replace rotted boards and re-flash every edge.
Roof Installation
New roofs on additions, rebuilt homes and new construction, with the deck prep, drainage and flashing details the code and manufacturer require.
Shingle Roofs
Storm-damaged and missing shingles, leaks at chimneys, valleys and vents, and full replacements with wind-rated architectural shingles. Shingle roofs in Brooklyn →
Roof Inspection
Surface, seams, flashing, parapets, drains, skylights and chimney, with photos and a written report. Useful for buyers, sellers, landlords and after storms.
Storm & Emergency Repair
Water coming in or shingles torn off? We make it watertight first, with a temporary seal or tarp if needed, then come back for the proper repair.

Why Brooklyn Roofs Leak, and Why the Patch Didn’t Work
About half of Brooklyn’s homes were built before 1939. Old brick, old wood decks and attached roofs that share walls with the neighbors make leaks harder to trace than on a suburban house. Add wind-driven rain off the harbor, freeze-thaw all winter and rooftop heat in summer, and small weak spots turn into ceiling stains.
Parapet and coping failures
Cracked coping stones, open mortar joints and loose counterflashing let water run down inside the wall and show up on the ceiling below.
Failed flashing
Where the roof meets a wall, chimney, bulkhead, skylight or the neighbor’s higher roof. It’s the most common leak source we find on flat roofs.
Ponding water
Flat roofs that sag or drain poorly hold water for days after rain, and that standing water breaks down seams and coatings.
Clogged drains and leaders
Leaves and city grit back water up over the flashing. Fall, when the street trees drop their leaves, is the worst time for it.
Too many layers
Roofs that were rolled over again and again trap moisture, rot the deck and can’t legally take another layer.
Shared walls and neighbor roofs
On attached homes, water from the house next door can travel along a party wall and come out in yours.

Brooklyn Roofs We Work On Every Day
From brownstone parapets to detached shingle homes near the water, every kind of Brooklyn building has its own weak spots. Here’s what we see most.
Brownstones and townhouses
Park Slope, Brooklyn Heights, Cobble Hill, Fort Greene, Bed-Stuy. Flat roofs behind parapets, with cornices, skylights and bulkheads, many in landmarked historic districts.
Rowhouses and two-family homes
Sunset Park, Bay Ridge, Bensonhurst, Borough Park, East Flatbush. Tar, torch-down or rubber roofs, shared parapets and rear drains that clog every fall.
Walk-ups, mixed-use and co-ops
Bigger roofs with rooftop equipment and more penetrations, plus the permits, insurance certificates and paperwork owners and boards need.
Victorian and frame houses
Ditmas Park, Prospect Park South, Fiske Terrace. Steep slate, shingle and metal roofs, where repairs should match the original materials.
Detached homes in south Brooklyn
Marine Park, Mill Basin, Bergen Beach, Gerritsen Beach. Pitched shingle roofs and gutters with more exposure to coastal wind and storms.
Commercial roofs
Storefronts, warehouses and mixed-use buildings. We schedule around tenants and businesses and keep the work area safe.
Roofing materials for Brooklyn buildings
| Roof system | Best for | Typical lifespan* | What to know |
|---|---|---|---|
| EPDM (rubber roof) | Brownstones, rowhouses | 20–30 years | Flexible through freeze-thaw; seams and edges must be detailed well |
| TPO | Flat roofs that need a white, cool surface | 15–25 years | Heat-welded seams; reflects summer heat |
| PVC | Mixed-use buildings, roofs with grease vents or equipment | 20–30 years | Heat-welded; resists grease and chemicals |
| Modified bitumen (torch-down) | Rowhouses, two-family homes | 15–20 years | Tough multi-ply roof; needs an FDNY-certified crew |
| Built-up (tar and gravel) | Older flat roofs | 15–25 years | Still common; often already at its last allowed layer |
| Silicone or aluminum coating | Sound roofs that need more years | 5–15 years per coat | Not a fix for wet insulation or rotted decking |
| Asphalt shingle | Detached and pitched roofs | 20–30 years | Choose wind-rated architectural shingles |
| Slate | Victorian and historic homes | 75–100+ years | Repair rather than replace whenever possible |
How Much Does a Roof Cost in Brooklyn in 2026?
Most flat roof repairs in Brooklyn cost $300–$1,500, and most brownstone flat roof replacements run $8,000–$32,000. Roof size, how many old layers come off, rotted deck boards, scaffolding, Landmarks approval and permits move the price the most.

NYC Roofing Rules We Handle for You
Roofing in New York City comes with more rules than almost anywhere in the country. Most homeowners don’t know them, and some roofers skip them. Here’s what applies to Brooklyn roofs, in plain English.
Home Improvement Contractor license
Anyone doing roof work on a NYC home needs a Home Improvement Contractor license from the Department of Consumer and Worker Protection (DCWP). Check the number before you sign anything.
DOB permits for replacements
Full roof replacements generally need a Department of Buildings permit, filed through DOB NOW. Most small repairs don’t.
FDNY rules for torch-down
Torch-applied roofing is legal in NYC when the crew holds the required FDNY certificates and a fire guard watches the roof during and after torching.
Landmarks (LPC) approval
In historic districts such as Brooklyn Heights, Park Slope, Fort Greene and Ditmas Park, roof work visible from the street needs Landmarks Preservation Commission approval.
Cool roofs, Local Laws 92 and 94
Replacement roofs must meet NYC’s reflectivity rules, and replacing an entire roof assembly can trigger a solar or green roof requirement.
Layers, parapets and neighbors
No new roof over two or more existing layers. Many street-facing parapets need a yearly observation on file. RPAPL 881 covers access when a neighbor refuses.
Rules change, so we check current DOB, LPC and FDNY requirements for every job.
