New construction means we start with a clean deck and build the roofing system properly from the first layer. Grandin Roofing & Maintenance has installed new roofs on hundreds of new builds across Grandin, from custom homes to spec builds, from room additions to detached structures.
Our New Roof Installation Process
Plan Review & Consultation
Meet with our Grandin 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
All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.
Expert Installation
Our Grandin 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.
Inspection & Warranty
We schedule the building inspection and walk the roof with the inspector. Your manufacturer warranty gets registered the same day the roof passes inspection. You receive warranty paperwork within a week.

Why Choose Grandin Roofing & Maintenance for New Roof Installation?
Code Compliance
Every installation meets IRC building code and local Grandin 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.
New Construction Specialists
We install new roofs on new builds every week. Our Grandin crews know the pace, the coordination, and the quality standards that new construction demands.
