Westchester Commercial Roofing FAQs
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 request a free assessment.
Do you handle emergency roof leaks in Westchester?
Yes. Our Port Chester location means fast response anywhere in the county. 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.

Regularly. We're experienced presenting to boards, working with managing agents and engineers, and phasing work around occupied buildings.
