Professional Roofing Services in Greenwich

"What sold me was the inspection report. Detailed photos of every damaged area, measurements, written explanation of what needed repair versus replacement. No other company gave us anything close to that level of documentation."

"Our flat roof on the garage had been patched five times by other companies. Oneco Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."

"The Golden Pledge warranty was a big factor in our decision. 25 years on workmanship plus 50 on materials. Oneco Roofing & Maintenance is one of the few local companies that can even offer it."

No Subcontractors

Every Greenwich roof is installed by our own trained crews, not subcontractors pulled from a labor pool. That means consistent quality, accountability, and a crew that knows our standards from the first nail to the last drip edge.

Manufacturer-Certified Installation

We hold certifications from GAF, Owens Corning, and CertainTeed. That means the manufacturers have trained and vetted our crews and will back our installations with their strongest warranties. Your Greenwich roof gets factory-level quality control.
