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 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

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 Milpitas?
General contractor pricing varies by project type. For a roof replacement, expect $15,000 to $35,000 for asphalt shingles on a standard home (Hamilton Exteriors 2024-2026 project data). For a home addition, costs range from $250 to $450 per square foot. Hamilton Exteriors provides fully itemized estimates so you see exactly where every dollar goes.
Do I need a permit for a roof replacement in Milpitas?
Yes. Milpitas requires a building permit for all roof replacements. The permit fee is typically $300 to $700 (Hamilton Exteriors 2024-2026 project data). Your contractor should pull the permit and schedule the required inspections. Hamilton Exteriors handles all permitting for every project.
What is the best roofing material for Milpitas?
Premium architectural asphalt shingles offer the best value for most Milpitas homes. They handle the valley's heat well, carry Class A fire ratings, and last 25 to 50 years. Metal roofing is a strong choice for homeowners planning to stay long-term, with a 40 to 70 year lifespan and excellent energy efficiency.
How long does a roof replacement take in Milpitas?
Most residential roof replacements take 2 to 5 days. A straightforward asphalt shingle job on a single-story home can be done in 1 to 2 days. Tile and metal roofs take longer, typically 5 to 10 days.
