When you're building new in Dunbarton, the roof is one of the most important decisions you'll make. It protects everything underneath it for the next 30-50 years. Dunbarton Roofing & Maintenance helps you choose the right material, designs proper ventilation, and installs it to manufacturer specifications.

Our New Roof Installation Process

1

Plan Review & Consultation

Meet with our Dunbarton 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.

2

Material Delivery & Staging

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.

3

Expert Installation

From underlayment to ridge cap, every layer installed in the correct sequence by certified crews. A project manager is on-site for new construction installs to ensure quality at every stage.

4

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.

Why Choose Dunbarton Roofing & Maintenance for New Roof Installation?

Full Manufacturer Warranty

Factory-certified installation means your new roof warranty is fully backed from day one. No gaps, no exclusions from improper installation.

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.

New Construction Specialists

We install new roofs on new builds every week. Our Dunbarton crews know the pace, the coordination, and the quality standards that new construction demands.

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.

New Roof Installation FAQ

One to three days for most residential projects. Standard homes are typically done in one day. Larger custom builds or complex multi-material roofs take two to three days. We coordinate timing with your GC.

Synthetic underlayment meeting ASTM D6757 across the full deck. Ice and water shield per ASTM D1970 at eaves, valleys, and all penetrations. These layers are critical. They're your last line of defense if the shingles fail.

Yes. We coordinate directly with your GC on scheduling, material staging, and inspections. We've subbed for dozens of builders across Dunbarton and understand the pace and expectations of new construction.
