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 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

The team dis an excellent job on our roof. Carlos and his team are punctual, communicative and kept the worksite clean throughout the project. There was a slight delay in the beginning but the whole process felt smooth and stress free. Alex was generous enough to add in extra service worth $759. Highly recommended, honest roofing work.

They offered a reasonable price for my roof replacement, and overall I’m satisfied with the work. The main issue was that it took quite a while to finish because of the permit process. At one point, I was worried that the roofing materials left at the property might be stolen, so I texted them about it. They responded to my message right away, which I appreciated, and luckily nothing was stolen. Overall, the price was fair, they were responsive when I had concerns, and the project was completed.

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.

How much does roofing cost in Sonoma County?

Roofing costs in Sonoma County vary by city — from Santa Rosa to Cotati. With median home values averaging $916,875 across the county, we see a range of project scopes. Hamilton Exteriors provides free, fully itemized estimates for every Sonoma County project — every cost spelled out.

What roofing materials work best for Sonoma County homes?

For Sonoma County homes in Sonoma County, we most often recommend asphalt architectural shingles for their balance of durability and value. Tile roofing is popular in neighborhoods like Santa Rosa for its aesthetic appeal, and metal roofs are ideal for energy efficiency in the Bay Area climate.

How long does a roof replacement take in Sonoma County?

Most roof replacements in Sonoma County take 3-5 days depending on the size and complexity. We handle all permits required by Sonoma County and keep your property clean throughout the process.

What roof maintenance do Sonoma County homeowners need?

In Sonoma County, we recommend annual inspections — especially after the rainy season. Sonoma County homes face hot, dry summers and seasonal rain, which accelerates wear on flashing, vents, and shingle edges. Homes in Sebastopol should also check for debris buildup from surrounding trees. Catching small issues early prevents costly replacements.
