Roofing
Our patented 7-part roofing system ensures durability and longevity. We use GAF-certified materials, including Timberline shingles, and offer 50-year non-prorated warranties. Our process includes a full roof strip, attic ventilation inspection, and debris cleanup, guaranteeing protection against extreme weather. Backed by decades of experience and thousands of satisfied customers, we ensure your roof enhances curb appeal while safeguarding your home investment.
Siding
We specialize in premium vinyl, fiber cement, and composite siding with a 6-7 inch reveal for superior storm resistance. Our KingWall siding includes a lifetime warranty against cracking, fading, and moisture damage. The process combines insulation benefits to reduce energy costs by up to 19%. With 23 designer color options and a focus on local climate resilience, we deliver both aesthetic appeal and functional protection for Long Island homes.
Replacement Windows
Our energy-efficient windows feature double-strength frames, insulated glass, and multi-chambered construction to cut energy bills by up to one-third. As Long Island's exclusive distributor of Simonton 9800 windows, we offer styles like double-hung, casement, and bay windows with lifetime guarantees. The installation process includes custom fitting, manufacturer-certified workmanship, and a focus on noise reduction and thermal efficiency for year-round comfort.
Gutter Guard
Our gutter guard systems prevent clogs while maintaining water flow, reducing maintenance needs by up to 90%. Installed alongside roofing projects, these guards protect against water damage to foundations and landscaping. The seamless design integrates with new or existing gutter systems, ensuring long-term functionality without compromising aesthetics. Backed by the same warranties as our roofing systems for comprehensive protection.
Attic Ventilation
Proper attic ventilation prevents mold, condensation, and structural damage. Our balanced intake/exhaust systems meet FHA standards, improving insulation efficiency and reducing summer cooling costs. The process includes diagnosing existing issues, recommending optimal vent placement, and installing high-performance solutions. Critical for maintaining roof longevity and indoor air quality, especially in humid coastal climates like Long Island.
