A new roof installation is your chance to get everything right from the start. No compromises, no working around someone else's mistakes. Cornwall Roofing & Maintenance installs new roofing systems on new homes, additions, detached garages, carports, and covered patios throughout Cornwall.
Our New Roof Installation Process
Project Planning
We analyze your plans for pitch, square footage, ventilation needs, and code compliance. You get a detailed proposal with material specs, timeline, and fixed pricing before any work begins.
Pre-Installation Setup
We coordinate delivery timing with your GC so materials don't sit exposed longer than necessary. Our staging crew organizes everything on the roof deck for efficient installation the next morning.
Expert Installation
Our Cornwall crew installs every layer to manufacturer specifications: underlayment, ice and water shield, drip edge, starter strip, field material, hip and ridge caps, and ventilation. Every fastener placed per the manufacturer nailing schedule.
Final Inspection
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Cornwall office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
