Greenport Roofing & Maintenance has replaced 236+ roofs across Greenport and Cape Vincent, Cutchogue, Fly Creek, Hempstead, Lansing. 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.
Our Greenport replacement crews install GAF, Owens Corning, and CertainTeed shingles. We carry manufacturer certifications from all three, meaning factory-trained installers and access to the best warranty programs available. We help you choose based on budget, color, and warranty goals.
Our Roof Replacement Process
Comprehensive Evaluation
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.
Written Estimate
You receive a written proposal with material specs, labor breakdown, timeline, and total cost. We price by the square and itemize everything. Compare apples to apples with any other quote.
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.
Warranty Activation
Three magnetic nail sweeps, during tear-off, after install, before we leave. Dump trailer hauled off. Job site clean. You approve the work and we register your manufacturer warranty on the spot.
