What We Do

Comprehensive construction
services for every need

From emergency roof repairs to full-scale renovations, ONE Construction and Roofing Contractors delivers the full spectrum of general contracting services across New York City.

Roofing

Complete roof installations, replacements, and repairs. From flat roofs to pitched systems, we work with asphalt shingles, EPDM, TPO, and built-up roofing — built to withstand New York weather.

General Contracting

Full-service general contracting for residential and commercial projects. We manage the entire process — permits, materials, labor, inspections — so you don't have to.

Renovations

Kitchen, bathroom, basement, and whole-home renovations. We transform spaces with attention to detail that turns your vision into something tangible and built to last.

Repairs & Maintenance

Emergency and scheduled repairs for structural, roofing, and exterior systems. Fast response times and transparent pricing — no hidden fees, no inflated invoices.

Exterior Work

Siding, windows, doors, decks, and masonry. We handle the exterior envelope so your property is protected, insulated, and visually cohesive.

Commercial Projects

Office build-outs, retail spaces, and commercial roofing. We understand timelines, codes, and the demands of business operations — and we plan around them.

About Us

Built on hard work,
backed by reputation

ONE Construction and Roofing Contractors has been serving New York City for over two decades. What started as a small roofing operation grew into a full-service general contracting firm — not through marketing, but through word of mouth from homeowners and business owners who saw what we built and wanted to recommend us.

We're licensed, insured, and rooted in this city. Our team includes tradespeople who've spent their careers mastering their craft — roofers, carpenters, masons, and project managers who treat every job like it's their own property.

When you hire ONE Construction, you're not getting a middleman or a subcontractor chain. You're getting a direct line to the people doing the work and the people who answer when something goes wrong.
