Roof City did an excellent job on my roof. They were professional, fast, efficient, and clean. They over- delivered on their promise to do a five- star job in two days, which included all materials and permits needed. They deserve a 10 star rating 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

Local Tip
Sunnyvale's "Birdland" neighborhood (streets named after birds) has one of the highest concentrations of original 1950s roofs in the South Bay. Many of these low-pitch roofs need modified bitumen or TPO instead of standard architectural shingles.

What areas do you serve?
We serve Northern California across three regions: the San Francisco Bay Area, Greater Sacramento, and the Central Valley. Our published guides cover 14 counties and 88 cities. Our Castro Valley and Sacramento offices support local estimating, permit coordination, and project planning across these regions.
How does billing and financing work?
Financing may be available for eligible projects with approved credit. Available terms depend on lender approval, project scope, and current programs. Your project manager can review the options that apply before work begins. We also accept checks, ACH, and major credit cards.
Are you licensed and insured?
Yes. Hamilton Exteriors holds CSLB License #1078806, active general liability coverage, and the required contractor bond. We also hold GAF Master Elite and James Hardie Elite Preferred credentials. We can provide current proof of coverage before work begins.
Do I need a permit for my exterior project?
Permit requirements depend on the project scope and local jurisdiction. Hamilton Exteriors coordinates required applications, plan documents, corrections, and inspections. Permit fees and allowances appear in the proposal before construction begins.
How much does a general contractor cost in Sunnyvale?
General contractor rates in Sunnyvale range from $150 to $250 per hour for labor, with project management fees typically 10 to 20 percent of total project cost (Hamilton Exteriors 2024-2026 project data). For a full roof replacement, expect $15,000 to $35,000. For a home addition, $80,000 to $300,000. Hamilton Exteriors provides itemized estimates so you see exactly what each component costs.
Do I need a permit for a roof replacement in Sunnyvale?
Yes. Sunnyvale requires a building permit for any roof replacement. Permit fees range from $400 to $800. Your contractor should pull the permit and schedule inspections. See the Sunnyvale building permit page for current fees.
What is the best roofing material for Sunnyvale's climate?
Premium architectural asphalt shingles offer the best balance of cost, durability, and fire resistance for most Sunnyvale homes. Metal roofing is a strong choice for fire-prone foothill properties and homeowners planning to stay long-term. Tile suits Spanish-style homes but adds significant structural load.
How long does a roof replacement take in Sunnyvale?
Most asphalt shingle roof replacements take 2 to 4 days. Tile and metal roofs take 5 to 10 days. Permit issuance adds 1 to 2 weeks before work starts.
Does Hamilton Exteriors handle ADU permits in Sunnyvale?
Yes. We handle all ADU permits, including plan review, building permits, and final inspections. Sunnyvale's ADU permit process typically takes 4 to 8 weeks for plan review. We manage the entire process.
