Looking for a Berkeley roofing contractor who brings an architect's eye to every project? Hamilton Exteriors provides roof replacement, repair, and installation services across Berkeley, from the Berkeley Hills to the flatlands. We are a GAF Master Elite contractor, a designation held by fewer than 3 percent of roofing contractors nationwide, and our work is led by Alex Hamilton Li, a licensed architect and general contractor (CSLB #1078806).
A roof replacement in Berkeley typically costs $18,000 to $28,000 for a standard 2,000-square-foot home with mid-grade asphalt shingles, including tear-off, underlayment, and cleanup (Hamilton Exteriors 2024-2026 project data). Premium materials like metal or tile can range from $30,000 to $55,000. Every estimate we provide is fully itemized — materials, labor, permits, and cleanup are listed separately so you see exactly where your money goes.
Why Berkeley Homeowners Choose Hamilton Exteriors

Roofing Materials We Install in Berkeley
The best material for your Berkeley home depends on your home's architecture, budget, and location. Here are the options we install:
Asphalt Shingles
The most popular choice for Berkeley homes. Modern architectural shingles from GAF, CertainTeed, and Owens Corning offer a 50-year system warranty, Class A fire rating, and 130 mph wind warranty. Installed cost: $940 to $1,125 per roofing square (100 square feet). Learn more about asphalt shingle roofing.
Metal Roofing
Ideal for fire-prone areas like the Berkeley Hills. Standing seam steel and aluminum panels last 40 to 70 years with virtually zero maintenance. According to research from Oak Ridge National Laboratory, metal roofs with reflective coatings can reflect up to 70 percent of solar energy, reducing cooling costs by 10 to 25 percent. Installed cost: $1,200 to $1,800 per square. Learn more about metal roofing.
Tile Roofing
Clay and concrete tile roofs are common on Mediterranean and Spanish-style homes throughout Berkeley. They last 75 to 100 years but add significant structural load — 9 to 12 pounds per square foot compared to 2 to 4 pounds for asphalt. Many older Berkeley homes need structural reinforcement before tile installation. Installed cost: $1,500 to $2,500 per square. Learn more about tile roofing.

Berkeley-Specific Considerations
Fire Zone Compliance
Parts of Berkeley, particularly the Berkeley Hills, are designated as Wildland-Urban Interface (WUI) Local Responsibility Areas by CAL FIRE. Homes in these zones must meet California Building Code Chapter 7A fire-resistant building standards. This requires:
- Class A fire-rated roofing materials
- Non-combustible vents and eave assemblies
- Fire-rated underlayment
- Ember-resistant ridge vents
- 1/8-inch mesh attic screens
We verify your property's fire zone designation using CAL FIRE's Fire Hazard Severity Zone map during your inspection and handle all required documentation for building department approval.
Coastal Fog and Corrosion
Berkeley's proximity to the San Francisco Bay means homes experience salt-laden marine air that accelerates corrosion of exposed metal components. Flashing, vents, and gutters on Berkeley homes require corrosion-resistant materials — stainless steel or aluminum rather than galvanized steel. We specify materials rated for coastal environments on every Berkeley project.
Seismic Considerations
Berkeley sits near the Hayward Fault, one of the most active fault zones in California. The U.S. Geological Survey estimates a 31 percent probability of a magnitude 6.7 or greater earthquake on the Hayward Fault within the next 30 years. During a roof replacement, we inspect and reinforce structural connections where needed, including tie-downs and shear wall connections that may be required by current building code.
Older Housing Stock
According to the U.S. Census Bureau American Community Survey, roughly 60 percent of Berkeley's housing stock was built before 1960. Older homes often have:
- 1x6 skip sheathing instead of plywood decking, which may need overlay
- Deteriorated fascia and soffit boards
- Outdated ventilation systems
- Lead paint or asbestos in older roofing materials
We address these conditions during your inspection and include any necessary upgrades in your itemized estimate.
Permits for Roof Replacement in Berkeley
Berkeley requires a building permit for all roof replacements. The Berkeley Permit Service Center handles applications. Permit fees for a standard roof replacement typically range from $400 to $900, depending on the scope of work. We handle the entire permit process — application, plan submission, and scheduling inspections — so you do not have to worry about it. Permit fees appear as a separate line item in your estimate.
How We Price Roof Replacements in Berkeley
At Hamilton Exteriors, we believe pricing should be transparent. Here is how our process works:
- On-site inspection. We visit your home to assess your roof's condition, measure the roof area, and identify any issues.
- Itemized estimate. You receive a written estimate with each cost component broken out: tear-off, underlayment, roofing material, flashing, ridge vents, labor, permit fees, and cleanup.
- Material options. We provide pricing for multiple material options so you can compare and choose what fits your budget.
- . You are welcome to take your time deciding. We will not call you every day asking for a decision.
