Roof Replacement in San Francisco, CA

What Roof Replacement Involves

Roof replacement means removing every layer of existing roofing material down to the deck, inspecting and repairing the underlying structure, and installing a brand-new system. This is not a repair or overlay—it's a complete renewal of your home's protective shell. We handle single-family homes, multi-unit buildings, and commercial flat roofs across San Francisco.

Materials and Methods We Use

We offer three primary material options for San Francisco homes. GAF Timberline HD architectural asphalt shingles provide a Class A fire rating and cost between $5.50 and $8.00 per square foot installed. Owens Corning Duration premium shingles feature SureNail technology for superior wind resistance, priced at $6.00 to $9.00 per square foot. Concrete tile with Class A fire rating costs $10.00 to $15.00 per square foot and excels in coastal salt spray environments.

For flat roofs common on Victorian and Edwardian homes, we install modified bitumen or TPO membranes with marine-grade fasteners and flashing to resist salt corrosion. All materials meet California Building Code 1505.2.1 for Class A fire rating, mandatory statewide and especially in Wildland-Urban Interface zones.

Cost Ranges for San Francisco

Typical roof replacement in San Francisco costs $8,000 to $15,000 for a 1,500-square-foot asphalt shingle roof. Concrete tile roofs run $15,000 to $25,000 for the same size. Factors affecting price include roof pitch, number of layers being removed, deck repairs needed, and accessibility for dumpsters and material delivery. We provide free estimates with itemized breakdowns so you know exactly what you're paying for.

Signs You Need Roof Replacement

Not every roofing problem demands replacement, but these signs indicate it's time. Shingles curling upward at edges or cupping means the asphalt has lost flexibility. Granule accumulation visible in gutters signals accelerated wear from granule loss due to intense California summer UV. Water stains on bedroom or attic ceilings point to leaks that have penetrated the deck. Visible daylight through roof deck gaps means the sheathing has rotted or pulled apart. Other red flags include widespread cracking from thermal cycling, wind damage from Santa Ana desert winds, and salt corrosion of metal fasteners on coastal homes.

Our Step-by-Step Process

1. Inspection and Permit

We start with a thorough roof inspection to assess deck condition, ventilation, and flashing. We then pull the required roofing permit from the San Francisco Department of Building Inspection. No work begins without a valid permit—this protects you and ensures code compliance.

2. Tear-Off and Deck Prep

Our crew removes all existing roofing material down to the deck. We inspect the plywood or plank sheathing for rot, replace damaged sections, and install new drip edge and ice-and-water shield at eaves and valleys. This step takes one to two days for an average home.

3. Underlayment and Flashing

We install synthetic underlayment over the entire deck for secondary waterproofing. New step flashing at walls, pipe boots, and chimney counterflashing are installed using marine-grade stainless steel fasteners to resist salt corrosion. This step takes one full day.

4. Shingle or Tile Installation

Our installers lay the primary roofing material according to manufacturer specifications. For asphalt shingles, we nail each shingle with six nails per shingle at the correct depth. For concrete tile, we use the approved fastening system for high-wind zones. This step takes two to three days.

5. Final Inspection and Cleanup

We schedule the city inspection to verify code compliance. Our crew performs a full site cleanup using magnetic sweepers and tarps, removing all debris and nails. We provide you with a final walkthrough and manufacturer warranty documentation.

Local San Francisco Considerations

San Francisco's coastal climate demands specific measures. Coastal salt spray requires marine-grade fasteners and flashing on all metal components. Class A fire rating is mandatory statewide, especially in WUI zones. Extreme temperature variations stress fasteners seasonally, so we use corrosion-resistant materials throughout. Our crews are familiar with the city's narrow streets, parking restrictions, and neighbor notification requirements—we handle all logistics so you don't have to.
