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 Expertise
Exterior Projects in San Jose, California
San Jose is the Bay Area's largest city with over 330,000 housing units. Neighborhoods like Willow Glen, Rose Garden, and Cambrian feature a mix of pre-war bungalows and mid-century ranch homes that are prime candidates for roof replacement.
The City of San Jose requires building permits for all roof replacements. San Jose offers an online permit portal that has streamlined the application process. Standard residential re-roof permits are typically processed within 1-2 weeks.
San Jose's South Bay location makes it one of the warmest cities in the Bay Area, with summer highs routinely exceeding 85°F. Cool roof materials and proper attic ventilation are especially important here for energy efficiency.

Local Tip
San Jose's online permit system is one of the most advanced in the Bay Area — re-roof permits can be submitted, tracked, and approved entirely online, often cutting a week off the traditional timeline.

Frequently Asked Questions
Didn't find the answer to your question? Call Now (650) 977-3351
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.
Do I need a permit for a roof replacement in San Jose?
Yes. San Jose requires a building permit for all roof replacements. Permit fees run $400-$800 depending on project scope. Your contractor should pull the permit and schedule inspections. We handle this for every project. See San Jose Building Division.
What roofing material is best for San Jose's climate?
Premium architectural asphalt shingles offer the best value for most San Jose homes: $940-$1,125 per square, 30-50 year warranty, Class A fire rating (Hamilton Exteriors 2024-2026 project data). Metal roofing makes sense in fire-prone foothills and for homeowners planning to stay 30+ years. Tile suits Spanish-style homes but adds significant structural load.
How long does a roof replacement take in San Jose?
Most asphalt shingle replacements take 2-4 working days. Tile roofs run 5-10 days. Metal standing-seam takes 4-7 days. Permit issuance adds 1-2 weeks before work starts. We schedule around San Jose's dry season (May-October) for best results.
Does Hamilton Exteriors serve all of San Jose?
Yes. We serve all San Jose neighborhoods including Almaden Valley, Willow Glen, Rose Garden, Cambrian Park, Evergreen, Berryessa, Downtown, and the foothills. We also serve all of Santa Clara County.
What is the best time of year for exterior work in San Jose?
April through October offers the most reliable weather for roofing, siding, and exterior work. November through February can work between rain events and often comes with 5-15% labor savings during the off-season.
