COMMON QUESTIONS

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 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 and condo boards?

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