When your roof is past its lifespan or has suffered extensive damage, a full roof replacement is the most cost-effective long-term solution. Greene Group Construction is Long Island's trusted roofing company for complete tear-off and replacement projects on Nassau and Suffolk County homes.
Our roof replacement process starts with a thorough inspection of your existing roof, decking, and attic ventilation. We remove all existing shingles and underlayment, inspect and replace any damaged or rotted decking, install proper ice and water shield barrier, synthetic underlayment, and premium architectural shingles that carry manufacturer warranties of 30 to 50 years.
We work with all major shingle manufacturers including GAF, CertainTeed, Owens Corning, and Tamko. Our crews are manufacturer-certified, meaning your warranty is fully backed by both Greene Group Construction and the shingle manufacturer.
As a certified installer for leading shingle brands, we can offer enhanced manufacturer warranties that extend coverage beyond standard terms — protecting your investment for decades.
