Architectural and premium shingle installation and replacement across Nassau and Suffolk County. GAF-certified installation with manufacturer warranties up to 50 years.
Architectural asphalt shingles are the dominant roofing material across Long Island — and for good reason. They offer an excellent balance of durability, appearance, cost, and wind resistance that suits Nassau and Suffolk County's climate extremely well.
As a GAF-certified roofing contractor, Greene Group installs shingles to factory specifications — which means our customers qualify for GAF's enhanced warranty programs, including the System Plus, Silver Pledge, and Golden Pledge warranties that non-certified contractors simply cannot offer.
We install GAF Timberline HDZ, GAF Timberline UHDZ, GAF Camelot, Owens Corning Duration, and other leading shingle products selected to perform in Long Island's coastal and storm-exposed environment.
GAF certification means our teams have completed factory training and our installations are eligible for manufacturer-backed warranties covering both materials AND labor — not just materials. This is the strongest protection available in roofing.
