COMMERCIAL ROOF REPAIR DONE BY OUR OWN CREWS
Leaks, failed flashings, ponding and storm damage on office buildings, apartment buildings, schools, clubs and municipal roofs across Westchester — diagnosed and repaired by the same self-performing crews that install our new roofs.
Find the actual leak
Water shows up far from where it gets in. We trace it at the roof — flashings, drains, penetrations, parapets and seams — before anything gets patched.
Flashing, drain & penetration repairs
Most commercial leaks start at the edges and openings: base and counter-flashings, drain clamping rings, pipe and equipment curbs, and coping joints.
Membrane & seam repairs
Matched repairs on TPO, EPDM, PVC, modified bitumen and built-up roofs, so the existing system and its warranty path stay intact where possible.
Repair or replace — a straight answer
If wet insulation or failed seams are widespread, patching only buys time. We document conditions with photos so owners and boards can budget the right fix.
Maintenance programs
Scheduled inspections, drain cleaning and small repairs that catch problems while they are still cheap — and extend the life of the roof you have.
Parapets, copings & sheet metal
Edge metal and copings fabricated in our Port Chester shop, and masonry repairs where the wall above the roof is letting water in.

WESTCHESTER COMMERCIAL ROOFING FAQS
Should we repair or replace our commercial roof?
It depends on how much of the roof is wet or failed, not on its age alone. If the leaks trace to flashings, drains or isolated seams, a repair is usually the right call. If wet insulation or seam failures are widespread, repairs only buy time. We inspect, photograph what we find, and give you both options in writing so you can budget. Call (914) 937-1030.
How much does a commercial roof replacement cost in Westchester County?
Every commercial roof is priced individually based on the system (TPO, EPDM, modified bitumen, built-up), roof size, tear-off requirements, insulation, access, and existing deck conditions — two similar-looking buildings can have very different costs. Rather than quote a misleading range, we provide a detailed, line-item estimate at no cost after inspecting your roof. Call (914) 937-1030 or schedule a building assessment.
Do you handle active roof leaks in Westchester?
Yes. Our shop and crews are in Port Chester, so we reach anywhere in the county without a long mobilization — we stabilize the leak first, then diagnose the underlying cause properly. Call (914) 937-1030.
What roofing systems do you install?
Built-up roofing, modified bitumen, TPO, EPDM, PVC, liquid-applied membranes, and vegetated (green) roof systems — matched to your building, budget, and warranty goals.
Are you licensed and insured to work in Westchester County?
Yes. Fully licensed and insured, with manufacturer certifications from GAF, Hydrotech, and Siplast, and MBE certification for public and institutional work.
Do you work with co-op boards and managing agents?
Regularly. We're experienced presenting to boards, working with managing agents and engineers, and phasing work around occupied buildings.
