West Islip Roofing & Maintenance has replaced 269+ roofs across West Islip and Garnerville, Hoosick Falls, Lockport, Napanoch, Peterboro. Every replacement starts with a full tear-off and decking inspection. We find the damage the old roof was hiding, fix it, and build a new system designed for NY weather conditions.
Material selection makes a real difference. We install GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark, all architectural shingles with Class A fire ratings and 130+ mph wind warranties. We walk you through the options so you pick the shingle that fits your budget.
Our Roof Replacement Process
Initial Assessment
Before we quote anything, we inspect everything. A 30-45 minute walkthrough of your entire roofing system. If you only need a repair, we tell you. If replacement makes more sense, we explain why.
Your Detailed Proposal
Our estimator builds your proposal same-day in most cases. Multiple material options at different price points: GAF, Owens Corning, CertainTeed, with warranty comparisons for each. No pressure, no expiration tricks.
Expert Installation
Our crews average 8+ years experience each. Tear-off, decking inspection, ice and water shield, underlayment, drip edge, starter strip, field shingles, hip and ridge caps, and ridge vent, installed in the correct sequence per manufacturer requirements.
Final Walkthrough
Our project manager inspects the finished roof against the manufacturer checklist. You get a written workmanship warranty from West Islip Roofing & Maintenance plus the manufacturer warranty registered directly with GAF, Owens Corning, or CertainTeed.
