COMMERCIAL ROOFING & RESTORATION
BROOKLYN, NYC
MBE-certified commercial roofing contractor for Brooklyn multifamily, mixed-use and NYCHA buildings. Roof replacements built to NYC code — LL92/94, energy code insulation, cool roofs. Self-performed.
Trusted by property owners, developers, public agencies, and institutional clients throughout New York, New Jersey, and Connecticut.
Brooklyn's building stock asks more of a roofing contractor than almost anywhere else: pre-war multifamily walk-ups with aging parapets, large affordable-housing campuses, and a wave of new mixed-use development where Local Laws 92 and 94 require sustainable roofing zones on new roofs. L&M Roofing works across all of it — as an MBE-certified, self-performing envelope contractor that has served New York City since 1970.
From new-construction waterproofing and green roof assemblies on developments like Coney Island Phase I and Vital Brooklyn, to phased reroofing and façade restoration on occupied residential buildings, our own crews — never sub-tiers — deliver the work under prevailing-wage and minority-owned business participation requirements that Brooklyn's public and institutional owners demand.
WHAT WE DO IN BROOKLYN
ROOFING SYSTEMS WE INSTALL
Brooklyn work spans the full range of systems we self-perform: hot fluid-applied rubberized-asphalt waterproofing (American Hydrotech) beneath vegetated roofs and pedestal-paver amenity decks on new construction; Siplast Parapro PMMA liquid-applied systems for occupied-building reroofing; modified bitumen and built-up assemblies on institutional buildings; and cold-applied systems where open flame is prohibited. Parapet, coping, and railing packages are fabricated in-house — one submittal package, one accountable installer.
MULTIFAMILY & MIXED-USE ROOF REPLACEMENT WHAT NYC CODE REQUIRES
Much of Brooklyn is pre-war apartment buildings and mixed-use walk-ups. On a roof replacement, three NYC rules decide what the job has to include — and an owner who knows them before bidding gets comparable prices.
Replacing the whole roof triggers Local Laws 92 & 94
When an existing building replaces its entire roof deck or roof assembly, NYC requires the Sustainable Roofing Zone to be covered 100% by a green roof, solar, or both. Fire Code access paths, equipment, parapets, stormwater systems and some small setbacks are excluded. A repair or partial replacement does not trigger it — so scoping the job correctly matters. NYC's green roof property tax abatement has been extended to June 20, 2027.

Exposing the deck means insulating to code
If the work exposes the roof sheathing or decking, the NYC Energy Conservation Code requires insulation to current levels (NYCECC C503.3.1 for most commercial and multifamily buildings) — which can also mean raising parapet flashings or bulkhead doors. Where zoning prevents insulating above the deck, the code requires other measures to offset the heat loss.

New roof coverings must be reflective
Recovering or replacing a low-slope roof covering brings in NYC's cool-roof rule (BC 1504.8): a minimum solar reflectance of 0.70 and emittance of 0.75, or SRI 78. It does not apply when the work is under 50% of the roof and under 500 sq ft, and green roofs, some ballasted roofs and recreation decks are exempt.

Case Study: Coney Island Phase I — Waterproofing & Amenity Decks
On the Coney Island Phase I mixed-use development, L&M self-performed the complete roofing and waterproofing scope: American Hydrotech hot fluid-applied rubberized-asphalt membrane with insulation and ballast, green roof zones, and pedestal-set concrete paver amenity decks — the exact assembly Local Laws 92/94 push new Brooklyn buildings toward. Our Brooklyn portfolio also includes multifamily new-construction roofing at Vital Brooklyn Phase 1. When the roof is also the residents' outdoor space, detailing and waterproofing have to be right the first time.

BROOKLYN ROOFING FAQS
Our building is replacing its roof — what does NYC require?
Three rules usually apply. Replacing the entire roof deck or assembly triggers Local Laws 92/94 (green roof and/or solar across the Sustainable Roofing Zone). Exposing the deck triggers energy-code insulation. And new low-slope coverings must meet the cool-roof reflectance rule. We price each item separately so you can compare bids. Call (914) 937-1030.
Which Brooklyn neighborhoods do you work in?
All of Brooklyn — from Bay Ridge, Fort Hamilton and Dyker Heights to Park Slope, Williamsburg, Greenpoint, Bed-Stuy, Flatbush and Coney Island. Our crews and shop are in Port Chester, and we work throughout New York City.
Do NYC's green roof laws apply to my Brooklyn building?
Local Laws 92 and 94 require a sustainable roofing zone — green roof or solar — on most new buildings and major roof replacements in NYC. We install compliant vegetated assemblies and the waterproofing beneath them, and can advise which path fits your building and budget. Call (914) 937-1030.
Can you reroof occupied multifamily buildings in Brooklyn?
Yes — phased work on occupied residential buildings is our specialty. We plan staging, protection, and scheduling around residents, and we have delivered multi-building programs on fully occupied campuses.
Are you MBE certified for city and state work?
Yes — L&M is a certified Minority-Owned Business Enterprise (MBE) with both New York City and New York State, and we regularly perform prevailing-wage public work.
Do you work with general contractors on new construction?
Both. GCs engage us as a specialty roofing and waterproofing subcontractor on new developments; owners and agencies engage us directly for restoration. Either way the work is self-performed by L&M crews.
