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 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

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 Hayward?
General contractor rates in Hayward vary by project type and complexity. For a typical roof replacement, expect $17,500 to $21,500 for asphalt shingles on a 2,000-square-foot home (Hamilton Exteriors 2024-2026 project data). For a home addition, expect $200 to $450 per square foot. Hamilton Exteriors provides fully itemized estimates so you see exactly where your money goes.
Do I need a permit for a roof replacement in Hayward?
Yes. Hayward requires a building permit for any roof replacement. Permit fees run $250 to $600 depending on the scope (Hamilton Exteriors 2024-2026 project data). Your contractor should pull the permit and schedule the required inspections. Hamilton Exteriors handles all permitting for Hayward projects.
What is the best roofing material for Hayward homes?
Premium architectural asphalt shingles from GAF, CertainTeed, or Owens Corning are the most popular choice for Hayward homes. They offer a 30- to 50-year warranty, Class A fire rating, and good performance in the Bay Area's mild climate. Metal roofing is a good option for homes in hillside fire zones or for homeowners planning to stay long-term.
How long does a roof replacement take in Hayward?
Most residential roof replacements in Hayward take 2 to 5 days, depending on the roof size, material, and complexity. A straightforward asphalt shingle job on a single-story home may take 1 to 2 days. Tile or metal roofs can take a week or more.
Does Hamilton Exteriors serve all of Hayward?
Yes. We serve all Hayward neighborhoods, from downtown to the hills. We also serve the entire Alameda County area, including Oakland, Berkeley, and Fremont.
