New construction means we start with a clean deck and build the roofing system properly from the first layer. Grannis Roofing & Maintenance has installed new roofs on hundreds of new builds across Grannis, from custom homes to spec builds, from room additions to detached structures.
Whether it's GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark, or a standing seam metal system, our Grannis 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
Plan Review & Consultation
Meet with our Grannis 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.
Preparation
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.
Certified 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.
Inspection & Warranty
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Grannis office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
