Architectural and impact-resistant asphalt shingle installation and replacement by GAF Certified contractors. The most trusted roofing material on Long Island — properly installed for maximum lifespan in Nassau and Suffolk County's coastal climate.
Architectural asphalt shingles are the dominant roofing choice for Long Island homes — and for good reason. They offer the best combination of durability, aesthetics, cost, and availability of contractor expertise. Properly installed with the right components for Long Island's climate, architectural shingles deliver reliable performance for 22–28 years.
As a GAF Certified contractor, Greene Group Construction installs GAF Timberline HDZ and CertainTeed Landmark shingles — the two most-installed products in Nassau and Suffolk County — with full manufacturer system warranties. Our installations include complete ice and water shield coverage, synthetic underlayment, code-compliant drip edge, ridge vent, and seamless flashing at every penetration.
We also install Class 4 impact-resistant shingles (GAF ArmorShield II, CertainTeed Landmark IR) for homeowners in exposed locations or those seeking insurance premium reductions. Many Long Island insurers offer 5–30% premium discounts for homes with Class 4 rated roofs.

Long Island's coastal environment is significantly harder on asphalt shingles than inland areas. Salt air from the Great South Bay and Long Island Sound accelerates granule loss and flashing corrosion. Nor'easters with 60+ mph gusts are common. Freeze-thaw cycles cause repeated expansion and contraction stress.
Proper installation for Long Island means: full ice and water shield coverage (not just at eaves — we run it up all valleys and around all penetrations), high-wind fastening (6 nails per shingle in storm zones), quality corrosion-resistant flashing metal, and proper attic ventilation to prevent ice dams and premature aging from heat buildup.
We see roofs installed by out-of-state storm chasers fail within 5–8 years due to improper coastal installation. Our crews are Long Island-based employees who understand these conditions because they live here.
