New construction means we start with a clean deck and build the roofing system properly from the first layer. Graff Roofing & Maintenance has installed new roofs on hundreds of new builds across Graff, 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 Graff 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
Design 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.
Preparation
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.
Expert Installation
Installation follows IRC building code and manufacturer requirements. Proper overlap, correct fastener patterns, sealed penetrations, and balanced ventilation. Our crews are factory-trained and know the installation manuals by heart.
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.
