New construction means we start with a clean deck and build the roofing system properly from the first layer. Discovery Bay Roofing & Maintenance has installed new roofs on hundreds of new builds across Discovery Bay, from custom homes to spec builds, from room additions to detached structures.
We install to manufacturer specifications and local Discovery Bay building codes. That means proper underlayment per ASTM standards, ice and water shield at eaves and valleys, correct nailing patterns, and ventilation sized to the space. Every component documented for your warranty registration and building inspection.
Our New Roof Installation Process
Project Planning
We analyze your plans for pitch, square footage, ventilation needs, and code compliance. You get a detailed proposal with material specs, timeline, and fixed pricing before any work begins.
Material Delivery & Staging
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.
Certified 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.
Warranty Registration
Final quality check against manufacturer installation requirements. Building inspection coordinated through our Discovery Bay office. Warranty registered directly with GAF, Owens Corning, or CertainTeed.
