SERVING LONG ISLAND AND NY FOR 35 YEARS
New Roof Installation for Nassau Homeowners
If you’re building a new home, completing a major addition, or finishing a teardown-rebuild in Nassau County, your new roofing system needs to be built for what Long Island actually delivers.
Coastal humidity, heavy nor’easter winds, and the salt air along the South Shore all affect how a roof performs over the long term — and how it’s installed from day one determines how well it holds up.
County Roofing Systems has been completing new roof installations across Nassau County for over 35 years.
We work alongside builders, general contractors, and homeowners managing their own projects, and we handle the full process from permits through final inspection.

A BEAUTIFUL NEW ROOF
New Construction Roof Installation
Full roof installation from deck to ridge cap on new residential and light commercial construction. We coordinate with your framing crew and general contractor to keep the roofing phase on schedule, manage permit inspections, and deliver an installation that meets manufacturer specifications for full warranty eligibility.
REBUILD YOUR ROOF
Teardown Rebuild Roofing
Nassau County sees steady teardown-rebuild activity, particularly in higher-value communities like Garden City, Manhasset, Roslyn, and along the North Shore. We complete new roof installations on these projects and are experienced with the architectural review requirements common in Nassau County’s established HOA communities.
ADDITIONS AND SECOND STORIES
Addition and Second-Story Roofing
Adding square footage in Nassau County often means building up rather than out — land availability makes additions a frequent choice across the county. We handle the roofing phase of addition and second-story buildouts, including proper integration and flashing where new construction meets existing structure.
FLAT AND LOW-SLOPE
Flat and Low-Slope Roof Installation
New construction in Nassau County frequently includes flat sections over attached garages, covered entries, or rear additions. We install membrane systems rated for Long Island’s temperature swings, freeze-thaw cycles, and heavy precipitation.

- Shingle installation — Applied in correct overlapping courses per manufacturer guidelines to ensure full warranty eligibility

County Roofing replaced my aging roof and all of the gutters. Keith was truly professional, performing the estimate, supervising the work, and keeping me informed at every step. The results were beautiful. I would not hesitate to recommend County Roofing Systems to anyone.
Our roof was a bit of a tricky project, but Keith’s crew handled every nuance flawlessly—right down to protecting the gutters and surrounding landscaping. The workmanship is top-tier; you can see and feel the quality in every shingle. Equally impressive, Keith was completely transparent about costs and timelines, and his quote was the most competitive we received by a mile.
I had County Roofing Systems install new vinyl siding and gutters and leaders. Keith was very professional as well as personable and really knew his craft. Keith was on site the entire time with his crew. The house came out perfect. Just want to say thanks to Keith and I would give 5 stars plus! Thanks again Keith for all your good work.
Had a fantastic experience with County Roofing! Keith was extremely thorough. He walked through every detail, explained all the color options, and offered thoughtful recommendations that made a big difference. His crew did an outstanding job, and our new roof looks absolutely amazing.
Highly recommend County Roofing to anyone looking for a reliable, skilled roofing team!
Recently had a new roof done by County Roofing, and am so thankful for having met Keith. He is fair with the price, knowledgeable about his work, patient, responsive and professional.
