Professional Greenvale Roofing Contractor. GAF Certified

GAF Timberline HDZ shingles with StrikeZone nailing area for Class 4 impact resistance rated to UL 2218. We install the full GAF Roof System. Cobra ridge vent, FeltBuster synthetic underlayment, Starter Match starter strip, and Seal-A-Ridge caps. That qualifies your Greenvale home for the Golden Pledge warranty: 25-year workmanship plus 50-year material.

Missing shingles cause water intrusion through the exposed underlayment and decking. We don't just replace the missing shingle. We check the deck for moisture damage with a Protimeter pin meter, replace any compromised underlayment, and weave new CertainTeed Landmark shingles into the existing pattern.

Wind speeds over 60 mph cause shingle tab lift and seal failure. Hail over 1" diameter causes fractures through the shingle mat to the fiberglass reinforcement. Our HAAG-trained inspectors know the difference between cosmetic damage and functional damage. That distinction determines your insurance payout.

We install new roofs on new construction, room additions, detached garages, and covered patios. Our Greenvale crews handle residential and light commercial. Standard install time is 1-3 days depending on size.

Metal roofing costs more upfront at $12-$22 per sq ft installed in Greenvale compared to $4-$8 for shingles. But it lasts 2-3x longer and your energy bills drop 15-25%. Math works out over time.

Architectural shingles are what 80% of Greenvale homeowners choose. They look better than 3-tab, last longer, and handle wind better. We install GAF Timberline, Owens Corning Duration, and CertainTeed Landmark.

Flat roofs need special attention. Water doesn't run off, it sits. We install TPO, PVC, EPDM, and modified bitumen systems designed to handle ponding water in New York's climate.

TPO is our most-requested commercial membrane in New York. Reflective, energy-efficient, and it welds together at the seams for a watertight bond. We install 60-mil and 80-mil systems with 15-20 year manufacturer warranties.

Half-round copper gutters with round downspouts. That's the premium install. We solder joints on-site using 50/50 tin-lead solder. Copper develops a natural patina in New York's climate within 5-7 years. For aluminum, we use Spectra Metals .027 gauge seamless with Raytec hidden hangers rated to hold 25 lbs per linear foot of ice and debris load.

We climb up, walk the entire roof, and document what we find with photos and measurements. Takes about 30 minutes. You see exactly what we see. No mysteries, no scare tactics.

Emergency tarping is the first priority. We cover the exposed area to stop water entry, then schedule the permanent repair once conditions allow. We don't charge extra for emergency tarp jobs. It's part of the repair cost.

Skylight installation costs $1,200-$3,500 in Greenvale depending on size, type, and roof pitch. That includes the unit, flashing kit, interior trim, and roof patch-in. We handle everything from the outside in.
