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 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

From the very first consultation, we knew we'd made the right choice. The team was knowledgeable and genuinely listened to our concerns about energy efficiency and design. We've already noticed a drop in our energy bills.

Local Expertise

Exterior Projects in Antioch, California

Antioch has experienced significant growth over the past two decades, with many newer homes built after 2000 in the eastern portions of the city. However, older homes in the downtown and Rivertown districts may need roof attention.

The City of Antioch Building Division requires permits for all roof replacements. Antioch is one of the more affordable areas in Contra Costa County, and roofing costs here tend to be slightly lower than in closer-to-Bay cities due to reduced material transport distances.

Local Tip

Antioch's Delta breeze cools summer evenings but also carries moisture that can promote algae growth on north-facing roof slopes. Algae-resistant shingles with copper granules are a smart choice for homes in this area.

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 a general contractor cost in Antioch?

General contractor pricing varies by project scope. For a roof replacement, expect $17,500 to $21,500 for a 2,000 sq ft asphalt shingle roof (Hamilton Exteriors 2024-2026 project data). For a home addition, $80,000 to $200,000 depending on size and finishes. Hamilton Exteriors provides fully itemized estimates so you see exactly where your money goes.

Do I need a permit for a roof replacement in Antioch?

Yes. The City of Antioch requires a building permit for any roof replacement. Permit fees run $250 to $800. Your contractor should pull the permit and schedule the required inspections. We handle all permitting on every project.

What roofing material is best for Antioch's climate?

Premium architectural asphalt shingles from GAF, CertainTeed, or Owens Corning offer the best value in Antioch. They handle 100°F summers well, carry Class A fire ratings, and last 30 to 50 years. Metal roofing is a strong alternative for homeowners planning to stay long-term, with 40 to 70 year lifespans and superior heat reflection.

How long does a roof replacement take in Antioch?

Most asphalt shingle roof replacements take 2 to 4 days from tear-off to cleanup. Tile and metal roofs take 5 to 10 days. Weather delays are rare in Antioch's dry summers, but we always plan for a weather window.

Does Hamilton Exteriors serve all of Antioch?

Yes. We serve all Antioch neighborhoods, from the older homes near downtown to newer subdivisions in the southern and eastern parts of the city. We also serve nearby communities in Contra Costa County including Pittsburg, Oakley, Brentwood, and Discovery Bay.
