Building a new home or adding on to your existing one? Dunnegan Roofing & Maintenance handles new roof installation from decking to ridge cap. We work with your general contractor or architect to coordinate scheduling, material selection, and code compliance for your Dunnegan build.
Our New Roof Installation Process
Plan Review & Consultation
We review your building plans, discuss material options, and calculate ventilation requirements. Roof pitch, attic space, local code amendments, and your aesthetic preferences all factor into the recommendation.
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.
Certified Installation
Our Dunnegan 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 Dunnegan office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
