Our New Roof Installation Process
Project Planning
Meet with our Cornish project coordinator to select materials, review color options, and confirm the installation scope. We work with your GC or architect to ensure the roof spec meets the overall building design.
Pre-Installation Setup
Materials delivered and staged on-site the day before installation. Shingle pallets, underlayment rolls, flashing stock, ridge vent, and fasteners, everything confirmed against the project spec sheet.
Professional Installation
Installation follows IRC building code and manufacturer requirements. Proper overlap, correct fastener patterns, sealed penetrations, and balanced ventilation. Our crews are factory-trained and know the installation manuals by heart.
Final Inspection
After installation: quality inspection, building department sign-off, manufacturer warranty registration, and cleanup. Your new roof is warranted from the day it passes inspection.

Why Choose Cornish Roofing & Maintenance for New Roof Installation?
Material Selection Guidance
Shingles, metal, flat systems. We install all of them and help you choose based on your budget, design, and the demands of ME climate.
Ventilation Design
We calculate intake and exhaust per IRC R806 for every new install. Balanced ventilation extends roof life and cuts energy costs. Most contractors skip this step.

Builder Coordination
We work directly with your GC on scheduling, staging, and inspections. On-time delivery and clean work that doesn't slow down the rest of the build.
