Roof Repair
We warranty every repair for 5 years. If the same area leaks again due to our workmanship, we come back free. That warranty is in writing and it means something because we're a local West Sayville company. We're not disappearing.

Storm Damage Repair
Wind speeds above 60 mph cause shingle tab lift and adhesive seal failure per ASTM D7158 testing protocols. Our West Sayville inspectors check the entire windward exposure. Not just the obvious damage. Poor ventilation causes ice dams which cause water intrusion under the shingle field during freeze-thaw cycles. We document all contributing factors so your insurance claim covers root-cause repairs, not just surface patches.

New Roof Installation
New construction underlayment per IRC R905 and ASTM D226 (felt) or ASTM D6757 (synthetic). Ice barrier per ASTM D1970 required at eaves in climate zones with average January temperature below 25°F. We install ice and water shield regardless. It's cheap insurance against ice dams and wind-driven rain. Drip edge per IRC R905.2.8.5 on eave and rake edges. Proper starter strip with factory sealant for wind resistance from day one.

TPO single-ply membrane in 60-mil or 80-mil thickness, fully adhered or mechanically attached over minimum R-25 polyiso insulation. Hot-air welded seams tested with a probe at every joint. We install per NRCA and manufacturer specifications with tapered ISO insulation creating minimum 1/4" per foot positive drainage.

Fully warranted by Carlisle, Firestone, or GAF.

Commercial Roofing
Your commercial roof has HVAC units, exhaust fans, plumbing vents, and satellite dishes punching through it. Every penetration is a potential leak point. We install prefabricated curbs, custom-welded flashings, and pitch pans that handle foot traffic and thermal cycling without failing.

Copper weathers to a green patina in New York's climate over 5-7 years.

Emergency Roof Repair
After we secure the tarp and stop the leak, we photograph and document everything while the damage is fresh. This documentation is critical for insurance claims. Adjusters want to see the damage before any repairs are made.

Skylight Installation
VELUX FS (fixed) and VS (vented) skylights installed with EDL flashing kits for shingle roofs. The multi-step flashing integrates with the surrounding shingle courses per IRC R903.2. We frame the curb with doubled 2x8 or 2x10 lumber (depending on rafter depth), install ice and water shield membrane around the entire curb perimeter, then set the skylight with factory sealant before weaving step flashing into the field. Top headwall flashing tucks under the upslope shingle course. Bottom sill pan diverts water onto the downslope shingles. Zero exposed sealant joints. Mechanical flashing only.
