FAQs
New Roof Installation: Your Questions Answered
We've been installing roofs in San Jose for 16 years. Here are answers to the most common questions we hear before a new roof installation.
How much does a new roof installation cost in San Jose?
Costs vary based on roof size, pitch, materials, and complexity. On average, homeowners in the South Bay spend between $8,000 and $25,000 for a standard asphalt shingle roof. We provide free, no-obligation estimates after inspecting your roof — so you know the exact price upfront.
How long does a new roof installation take?
Most residential installations take 2 to 5 days, depending on weather and roof complexity. We'll give you a timeline during your estimate and keep you updated daily.
Do you handle insurance claims for roof replacement?
Yes, we handle insurance claims from start to finish. Our team works directly with your adjuster to ensure your claim covers the full scope of work — including materials, labor, and any code upgrades.
What roofing materials do you install?
We are factory-certified for Malarkey, CertainTeed, GAF, and Owens Corning. We install asphalt shingles, metal roofing, tile, and flat roofing systems — always using manufacturer-approved methods to keep your warranty intact.
Do you offer a warranty on new roofs?
Every roof we install comes with a manufacturer warranty on materials and our own workmanship warranty. We also guarantee a thorough cleanup after every job — no surprises.
Can I stay in my home during installation?
Yes, most homeowners stay home during the installation. We'll let you know what to expect — some noise and vibration during tear-off, but we keep the site safe and clean throughout.
How do I know if I need a full replacement vs. repairs?
If your roof is over 20 years old, has widespread shingle damage, or leaks in multiple spots, a full replacement is usually more cost-effective. We'll inspect your roof and give you an honest recommendation — no pressure.
What sets South Bay Roofing Co. apart from other roofers?
