Best Roofing Materials for Long Island Homes: 2025 Comparison

By Greene Group Construction Corp · Nassau & Suffolk County Roofing Experts

Not all roofing materials perform equally on Long Island. The combination of coastal humidity, salt air, harsh nor'easters, and summer heat requires materials that can handle real punishment. This guide helps Nassau and Suffolk County homeowners make the right choice before investing in a roof replacement.

Architectural Asphalt Shingles — The Long Island Standard

Dimensional shingles are the most common roofing choice on Long Island for good reason: they offer solid performance (20–27 years in coastal conditions), wide availability, and the best cost-to-lifespan ratio. GAF Timberline HDZ and Owens Corning Duration shingles are top performers. For a GAF-certified installer, look no further — Greene Group is a GAF Certified Contractor.

Impact-Resistant Shingles — Best for Storm Zones

Class 4 impact-resistant shingles are worth the 20–30% premium for homeowners in storm-exposed areas. They resist hail, wind-driven debris, and temperature extremes better than standard shingles. Many insurers offer discounts for homes with Class 4 shingles — making them especially smart for towns like Babylon, Amityville, and Wantagh that see direct storm exposure.

Metal Roofing — Best Long-Term Investment

Standing seam steel and aluminum roofing last 35–60 years in Long Island's coastal climate. Metal handles nor'easters, ice, and salt air better than any shingle product. The higher upfront cost ($21,000–$48,000+ for most Long Island homes) is offset by longevity and minimal maintenance. See our complete roof replacement service page for options.

Flat Roofing (TPO / EPDM) — For Low-Slope Roofs

Many ranch homes, additions, and commercial-style properties on Long Island have flat or low-slope sections that require a membrane system. TPO is the current preferred option for new installations. Read our dedicated guide on flat roofing on Long Island for specifics on materials, maintenance, and costs.

Cedar Shake — Beautiful But High-Maintenance

Cedar shakes look stunning but require regular treatment in Long Island's humidity. Without proper sealing and maintenance, moss and moisture penetration shorten their lifespan to 15–20 years. They're most common in upscale North Shore communities like Port Washington, Great Neck, and Roslyn.

What We Recommend for Most Long Island Homeowners

For budget-conscious homeowners: architectural shingles (GAF or Owens Corning). For storm-zone or insurance-discount priority: Class 4 impact-resistant. For maximum longevity: standing seam metal.
