Commercial roofing across Manhattan, Brooklyn, the Bronx, Queens, Staten Island, Westchester, and Nassau, backed by MBE, DBE, and LBE certifications. OSHA-compliant crews, $2 million in general liability coverage, and 24/7 emergency response since 2004.
$2M general liability insurance
Commercial roofing carries a different set of risks than residential work. A flat roof over a warehouse fails differently under weather than a pitched roof over a house. A leak over a data closet or a hospital floor has consequences a homeowner never has to weigh.
We work on office buildings, warehouses, multifamily properties, retail centers, industrial facilities, and institutional buildings, including government, healthcare, and education.
A property manager running a mixed portfolio shouldn’t need three vendors for three building types. We handle the work under one contract, one point of contact, and a roofing team that understands the difference between a school roof and a warehouse roof.
We handle the full range of commercial roofing work, from stopping an active leak to repairing, maintaining, inspecting, and replacing the roof.
A leak doesn't wait for a service window. We respond immediately to stop active water intrusion, then schedule the permanent repair.
Isolated leaks, damaged flashing, a failed seam: we fix each on its own timeline, without inflating the job into a bigger project than the roof needs.
Scheduled visits catch small problems while they're still small and cheap to fix.
We document the roof's condition before you commit to a repair, a purchase, or a budget cycle.
The right system depends on the building, its slope, and what it needs to withstand. We don’t apply the same default to every job.
We use these on most flat and low-slope commercial roofs. They hold up well and install straightforwardly.
For buildings where a heavier, multi-layer roof outperforms a single membrane
For roofs with complex penetrations or irregular geometry a membrane can’t cover cleanly
We apply these when cutting solar heat gain matters to the building’s energy costs.
For buildings where longevity and a distinct appearance both matter
We hold MBE, DBE, and LBE certification. We provide certification documentation directly to procurement teams and general contractors verifying participation or qualification requirements.
For facilities teams managing institutional or government projects, this documentation often satisfies a bid’s participation requirements directly.
Every crew follows OSHA safety standards, and every job carries $2 million in general liability coverage. We provide certificates of insurance on request before work begins.

Contacted this company and spoke with a representative named Ahmed as the building I work in was looking for roofing contractor. Coincidentally there is another Ahmed at NYC Commercial Roofing who I also contacted as I wanted to weigh different options. (They’re the same). Made an appointment for him to come Monday at 11am. He said he would call 30 min before to confirm. He didn’t, so I called. He told me he’s feeling sick. I don’t know why he couldn’t call me to let me know but I let it slide. We scheduled for the day after tomorrow for 3pm. He never came. I called many times and no one picked up. While I was hoping to meet them, they ended showing their unprofessional side. Things like this are just disappointing and now my team or I would never call to do business with them.Posted on Google![]()

We had our roof and siding replaced on our house. It was easy from beginning to end.he came out when he said he would, the written estimate gave you a lot of detail so you know what you were getting,and was always communicative throughout the process. I felt comfortable dealing with him team . Too many times the construction guys want to deal with me but I developed a good rapport and he was fantastic to work with. I can’t go on and on enough about how good the quality of their work was.attention to detail. There is no sloppy work here with him team.unfortunately , there were some issues with the interior of the house due to the thin walls of an old home . Adam , coordinated the workers to fix the issues promptly and without too much fuss. I am incredibly happy with the resolution. These guys are 5 stars and I would recommend him company to anyone.

Three boroughs, three service types, ten years. We’ve repaired roofs on tight timelines, replaced one past its service life, and maintained one to help extend its service life.
All five boroughs, plus Westchester and Nassau counties.
Commercial roofing in a dense city has its own logistics apart from the roofing itself: staging materials with no ground-level yard, coordinating access while the building stays occupied, working around a loading dock schedule that belongs to someone else’s business. That’s part of the job before a single roll of membrane goes down.
We work primarily on flat and low-slope systems: single-ply membranes, built-up, modified bitumen, and metal, across office, industrial, institutional, and multifamily properties.
Often, yes. Many public bids set aside participation goals for certified MBE, DBE, and LBE contractors. Ask us for our certification documentation when you’re reviewing a bid requirement.
Yes. Active leaks and storm damage don’t wait for a scheduled appointment. We respond to stop the immediate damage before scheduling the full repair.
All five boroughs: Manhattan, Brooklyn, the Bronx, Queens, and Staten Island, plus Westchester and Nassau counties.
Yes. We carry $2 million in general liability insurance and provide certificates on request.
Give us the address and what you’re seeing. We’ll tell you what it actually needs. No quote goes out before someone has looked at the roof.
