What Is New Roof Installation on Long Island?
New Roof Installation on Long Island typically costs $10,000–$25,000+ and must be performed by a contractor holding a Nassau or Suffolk County Home Improvement Contractor (HIC) license. Long Island Roofing Pros does not do this work itself: we connect you with an independent local roofer who inspects your roof and gives you a free written estimate.
Long Island’s coastal climate (nor’easters, salt air near the coast, and repeated freeze-thaw cycles) puts more stress on roofs than many inland markets. The National Roofing Contractors Association (NRCA) offers consumer guidance on hiring a qualified roofer. Whoever you hire, verify their county license and insurance, and make sure they pull any required building permit.

New Roof Installation FAQ
Answers to common questions from Long Island homeowners.
For most Long Island homes, architectural asphalt shingles offer the best balance of cost, durability, and wind resistance. For coastal homes (South Shore, Hamptons), metal roofing handles salt air and high winds better. Major manufacturers such as CertainTeed, GAF, and Owens Corning all make shingle lines suited to Long Island's climate.
For coastal homes, absolutely. Metal roofs generally handle salt air, high winds, and snow loads better than asphalt, and typically last 40+ years. The higher upfront cost (often $15K-$54K on Long Island) is offset by longevity and lower maintenance.
Typically a manufacturer warranty on materials (often 25-50 years), a workmanship warranty from your contractor on labor (terms vary widely, so get it in writing), and sometimes an extended system warranty if the contractor is certified by the manufacturer.
Three systems dominate on Long Island: (1) Standing seam aluminum — well suited to coastal homes near salt water; (2) Stone-coated steel — looks like shingles or tile, popular in historic districts like Cold Spring Harbor and Garden City; (3) Aluminum shingle — ideal for retrofit over existing asphalt. Many products in all three categories carry Class A fire (UL 790) and Class 4 impact (UL 2218) ratings; check the specific product.
