When you're building new in San Jose, the roof is one of the most important decisions you'll make. It protects everything underneath it for the next 30-50 years. South Bay Roofing Co. helps you choose the right material, designs proper ventilation, and installs it to manufacturer specifications.
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.
New roof pricing depends on material choice, roof size, and pitch. Architectural shingles in San Jose run $350-$550 per square installed. Standing seam metal is $12-$22 per square foot. We provide detailed proposals with exact pricing for your specific project.
Our New Roof Installation Process
Plan Review & Consultation
Meet with our San Jose 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.
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.
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.
Final Inspection
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.
