When you're building new in Dorr, the roof is one of the most important decisions you'll make. It protects everything underneath it for the next 30-50 years. Dorr Roofing & Maintenance helps you choose the right material, designs proper ventilation, and installs it to manufacturer specifications.
Whether it's GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark, or a standing seam metal system, our Dorr crews install it the way the manufacturer requires. Factory-certified installation means your warranty is fully backed from day one.
Our New Roof Installation Process
Design 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.
Material Delivery & Staging
All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.
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.
Warranty Registration
After installation: quality inspection, building department sign-off, manufacturer warranty registration, and cleanup. Your new roof is warranted from the day it passes inspection.
