We’ve been climbing Williamsburg roofs since 2016. We know the 4-story brick tenements on Berry Street with their 1920s tar-and-gravel decks. We know the converted warehouse lofts on North 3rd with factory-era roof spans now loaded with HVAC and satellite gear. And we know the new condos near the waterfront where salt air off the East River eats seams faster than inland Brooklyn ever sees. Williamsburg is not a shingle town. It’s a flat-roof, membrane, and parapet town, and that changes everything about how you hire.

Our Roof Replacement & Installation Services in Williamsburg
Flat Roofing
This is the work that defines Williamsburg. The 1890s-1920s tenements on Bedford Avenue, the converted factories along Kent, the 2000s condos near Domino Park - all flat roofs, all low-slope membrane geometry. We install modified bitumen, TPO, and EPDM systems, with full NYC DOB permit filings and parapet wall flashing as standard scope. Every job includes load calculation review for rooftop equipment and deck footings. On the older tenement blocks, we budget for full penetration re-flashing on nearly every tear-off, because decades of uncoordinated satellite dishes, condensing units, and water-tower supports have punched through original built-up roofing. The patched bitumen around those penetrations is almost always the active leak source, not the field membrane itself. We know to look there first.
Full Roof Replacement
A full replacement on a typical North Brooklyn tenement means stripping to the deck, inspecting for rot in 80-130-year-old wood plank or concrete substrates, and installing a new membrane system with proper insulation and drainage. We recently replaced the aging built-up roof on a 1920s warehouse-turned-loft on North 3rd Street. The original tar-and-gravel membrane had been punctured by decades of uncoordinated satellite dishes and water-tower supports. We stripped it to the deck, re-flashed every penetration with new TPO collars, and installed a fully adhered TPO membrane - required because the building’s proximity to the East River demands salt-air-resistant seams. Timeline: 5-7 days for a 3,000-square-foot deck, plus DOB permit lead time.
New Construction
Williamsburg’s new residential builds, whether boutique condos on Grand Street or mixed-use developments near the L train, require roofing contractors who understand NYC energy code, cool roof mandates, and green roof readiness. We coordinate with structural engineers on load-bearing capacity, especially for amenity decks and photovoltaic arrays. Our crews are authorized installers for Atlas and Tamko membrane systems, and we carry the full manufacturer warranties that transfer to building owners and condo associations.
Metal Roofing
While true pitched metal roofs are rare in Williamsburg’s flat-roof core, metal plays a critical role in every job we do here. Parapet coping, scupper boxes, through-wall flashing, and equipment curbs - all Gutters & Accessories - Williamsburg specialties - require fabricated metalwork that withstands salt-air corrosion. We specify 24-gauge Kynar-finished steel or copper for waterfront buildings where standard galvanized flashing would fail in under a decade. On converted industrial lofts, we often fabricate custom metal walkways and equipment platforms that protect the membrane below while providing safe access for maintenance crews.
Asphalt Shingles
Shingle work in Williamsburg is limited to carriage houses, rear-yard structures, and occasional pitched additions on larger loft conversions. When we do install shingles, we use IKO and Atlas architectural lines with full underlayment and ice-barrier systems. But we will not sell you shingles for a flat roof. We’ve seen too many “contractors” from out of state try that move on Williamsburg homeowners. It does not work. It leaks. We do not do it.
Tile Roofing
Clay and concrete tile appears occasionally on Spanish Revival infill or custom single-family renovations near McCarren Park. These jobs demand structural verification - tile weighs 800-1,000 pounds per square, and 1890s tenement roof decks were not engineered for that load. We coordinate with structural engineers and file DOB alteration permits when reinforcement is required. Our tile installations use proper battens, underlayment, and valley flashing that meets NYC wind-uplift standards.

Trusted Brands We Service in Williamsburg
We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Williamsburg’s flat-roof market, we most often specify Atlas and Tamko TPO and modified bitumen systems, with IKO underlayment and accessory products on the occasional shingle job. We stock common membrane widths, adhesives, and penetration flashing components at our Brooklyn facility, which means faster turnaround on repairs and no “we’ll order that” delays on replacement jobs. Every installation carries the full manufacturer warranty plus our own 90-Day Done Right Promise on workmanship.
Common Roof Replacement & Installation Problems We See in Williamsburg Homes
- Improper flashing of multiple rooftop penetrations. Condensing units, satellite dishes, deck footings, and water-tower supports have been added to Williamsburg tenement roofs for decades without coordinated waterproofing. The patched tar around each penetration becomes a leak highway. We strip and re-flash every penetration on replacement jobs.
- EPDM seam adhesive failure from salt-air exposure. Williamsburg’s position on the East River peninsula means elevated humidity and corrosive salt air that breaks down EPDM seam tape faster than inland Brooklyn. We see this most on buildings west of Wythe Avenue, closest to the water. Fully adhered TPO or heat-welded modified bitumen performs better here.
- Inadequate structural load consideration for rooftop amenities. In converted industrial lofts along the East River, original flat roofs were engineered for factory loads, not modern rooftop HVAC units and amenity decks. Any new installation must factor in structural reinforcement and DOB-mandated load calculations. We coordinate this engineering as part of our standard scope.
- Parapet wall deterioration hiding membrane termination failure. The brick parapets on 1920s tenements crack, spall, and lose coping stones. Water enters behind the parapet flashing and rots the roof edge from the inside out. We inspect parapet integrity on every replacement and rebuild or re-flash as needed.

FAQs - Roof Replacement & Installation in Williamsburg
All roof replacements in New York City require a Department of Buildings permit, and Williamsburg’s flat-roof stock triggers additional scrutiny for structural load, energy code compliance, and parapet safety. We handle every filing, from application to sign-off, as part of our standard service. Call (866) 756-1978 and we’ll walk you through your building’s specific requirements - estimates are free.
It is almost always the penetrations. On 1920s tenements, decades of uncoordinated satellite dishes, HVAC units, and water-tower supports have punched through original tar-and-gravel membranes. The patched bitumen around each penetration fails before the field membrane does. We inspect every penetration with photo documentation and re-flash as needed during replacement. Call (866) 756-1978 for a free inspection.
Almost certainly yes. Original industrial roof decks along the East River were engineered for factory loads, not modern amenity decks with furniture, planters, and foot traffic. NYC DOB requires structural load calculations and often reinforcement drawings signed off by a licensed engineer. We coordinate this engineering and file the alteration permits as part of our new construction and replacement services. Call (866) 756-1978 to discuss your specific building.
For Williamsburg buildings west of Wythe Avenue, near the East River, we typically recommend fully adhered TPO over EPDM. The salt-air exposure and elevated humidity in this peninsula location accelerate EPDM seam adhesive failure. TPO’s heat-welded seams resist salt corrosion better and carry stronger manufacturer warranties for waterfront applications. For buildings further inland, EPDM remains a viable option. Call (866) 756-1978 and we’ll specify the right membrane for your exact location.
Once NYC DOB permits are approved, a full replacement on a 3,000-4,000 square foot tenement roof takes 3-5 business days for stripping and membrane installation, plus 1-2 days for parapet work and final inspection. Permit lead time varies from 2-6 weeks depending on filing type. We keep work sites clean and minimize disruption to residents. Call (866) 756-1978 for a timeline estimate specific to your building.
