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 Palo Alto?
General contractor pricing in Palo Alto varies by project type. Roof replacements run $22,000 to $28,000 for a standard asphalt shingle roof (Hamilton Exteriors 2024-2026 project data). ADUs cost $180,000 to $280,000. Home additions range from $250 to $450 per square foot. Every Hamilton Exteriors estimate is fully itemized so you see exactly what each component costs.
Do I need a permit for a roof replacement in Palo Alto?
Yes. Palo Alto requires a building permit for all roof replacements. The Palo Alto Building Division reviews plans and conducts a final inspection. Permit fees run $500 to $1,100. Hamilton Exteriors handles all permit applications and inspections.
What roofing material is best for Palo Alto's climate?
Premium architectural asphalt shingles from GAF, CertainTeed, or Owens Corning are the most popular choice, balancing cost, durability, and fire resistance. For homes in fire-prone foothill areas, metal roofing offers superior Class A fire protection and a 40- to 70-year lifespan. Tile is common on Mediterranean-style homes but requires structural reinforcement due to its weight.
How long does a home addition take in Palo Alto?
A typical single-story addition takes 4 to 6 months from permit approval to completion. Design and permitting add 2 to 4 months before construction begins. Complex projects, including second-story additions, can take 8 to 12 months total. We provide a detailed timeline with every proposal.
Does Hamilton Exteriors serve all of Santa Clara County?
Yes. We serve all cities in Santa Clara County, including San Jose, Palo Alto, Mountain View, Sunnyvale, Cupertino, Los Gatos, Saratoga, and Morgan Hill. We also serve Alameda, Contra Costa, Marin, Napa, and San Mateo counties.
