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 Los Gatos, California

Los Gatos has approximately 12,000 housing units. The charming downtown area features historic homes from the early 1900s, while hillside neighborhoods offer larger custom homes with premium roofing requirements.

Los Gatos requires building permits for all roof replacements. Properties in the Historic Preservation Zone have additional review requirements to ensure roofing materials are compatible with the home's architectural character.

Hillside neighborhoods in the Santa Cruz Mountains foothills, including areas near Lexington Reservoir, are in designated WUI fire zones. Class A fire-rated materials are required, and brush clearance is enforced.

Local Tip

Los Gatos's Historic Preservation Zone covers much of downtown — roofing projects on designated properties require compatibility review. Natural wood shake look-alikes in composite material are the most popular approved alternative to original wood roofs.

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 Los Gatos?

General contractor rates in Los Gatos vary by project type. For a roof replacement, expect $19,500 to $24,000 (Hamilton Exteriors 2024-2026 project data). For an ADU, $250,000 to $500,000. Hamilton Exteriors provides itemized estimates so you see exactly where every dollar goes.

Do I need a permit for a home addition in Los Gatos?

Yes. The Town of Los Gatos requires permits for most structural work, including additions, roof replacements, and ADUs. Permit fees vary by project scope. Hamilton Exteriors handles all permit applications and inspections.

What is the best roofing material for a Los Gatos home?

For most Los Gatos homes, premium architectural asphalt shingles offer the best balance of cost and performance. In the hillside fire zones, metal roofing is recommended for its Class A fire rating and 40 to 70 year lifespan.

How long does a roof replacement take in Los Gatos?

Most asphalt shingle roof replacements take 2 to 4 days. Metal and tile roofs take longer, typically 5 to 10 days. Permit issuance adds 1 to 2 weeks before work starts.
