New construction means we start with a clean deck and build the roofing system properly from the first layer. Alstead Roofing & Maintenance has installed new roofs on hundreds of new builds across Alstead, from custom homes to spec builds, from room additions to detached structures.
Our New Roof Installation Process
Plan Review & Consultation
Meet with our Alstead 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
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.
Professional 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.
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 Alstead 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.
Code Compliance
Every installation meets IRC building code and local Alstead amendments. Proper underlayment, ice barrier, and fastener patterns documented for inspection.
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.
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.
