New construction means we start with a clean deck and build the roofing system properly from the first layer. Gilmanton Roofing & Maintenance has installed new roofs on hundreds of new builds across Gilmanton, from custom homes to spec builds, from room additions to detached structures.
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
All materials verified against your approved proposal. Color, brand, quantity, everything double-checked before install day. No substitutions without your approval.
Certified Installation
Our Gilmanton 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.

About Our Gilmanton New Roof Installation Services
Proper ventilation is the most overlooked element in new roof installation. We calculate intake and exhaust requirements per IRC R806 based on your attic square footage. Balanced ventilation (soffit intake matched to ridge exhaust) keeps your attic cooler in summer and drier in winter, extending roof life and reducing energy costs.
We handle everything from permits through final inspection. Our Gilmanton office pulls the roofing permit, coordinates material delivery, schedules the crew, and arranges the building inspection. Your GC or project manager gets regular updates and we stay on schedule.
