Metal Roof Replacement in San Francisco: Tear-Off, Deck Repair, New Metal System

A metal roof replacement in San Francisco starts with a full tear-off, not another layer of shingles stacked on a 1920s Sunset stucco row house. We haul away the old roofing, inspect and repair the decking, then install a complete new metal system sized for your block, your pitch, and your parapet. From Pacific Heights Victorians with ornate cornices to Noe Valley cottages and Twin Peaks hillside homes, we work the steep lots, tight side yards, and fog-belt details that make this city different from anywhere else in the Bay Area. A metal roof weighs far less than tile or composition shingles, and that reduced load matters on older San Francisco framing in an earthquake.

Why San Francisco Roofs Reach End of Life Faster Than Homeowners Expect

The dominant failure mode here is not snow load or hail. It is decades of moisture cycling: marine fog rolling in off the Pacific, cool damp winters with atmospheric-river storms, and salt air that attacks fasteners and flashing on older roofs. Add redwood and eucalyptus litter in the Richmond and Sunset, and the debris traps water against shingles and tile. On 1880s-1910s Victorians and Edwardians, roof edges, valleys, and parapet flashings are usually the first to go.

• Composition shingles on 1930s-1950s Sunset and Richmond row houses curl and granulate after 18 to 22 years of fog cycling.
• Cracked red clay tile on Marina and Mediterranean Revival roofs lets water into the underlayment long before the tile itself looks bad.
• Original metal roofs on older commercial and mixed-use buildings lose screws and washers, and that is when leaks start.
• Hillside homes on Bernal Heights and Diamond Heights get wind-driven rain pushed under flashings at gable ends and chimneys.

When two or more of these show up on the same roof, replacement usually costs less over ten years than repeated patching.

Key info: A Noe Valley Edwardian with a low-slope rear roof and a street-facing bay window needs a different panel profile and flashing detail than a flat-roofed Sunset row house. We size the system to the actual roof, not to a catalog page.

San Francisco roofing permits are commonly required for a full replacement, and thresholds and inspection requirements vary by jurisdiction. Verify current rules with the San Francisco Department of Building Inspection before you schedule work.

How We Replace a Metal Roof on a San Francisco House

We do not start swinging hammers on day one. First we walk the roof, check the decking from above and below where accessible, and photograph every flashing, valley, and penetration. Then we set a tear-off sequence that keeps the house dry overnight, because fog and winter rain do not wait for a convenient schedule. On steep Twin Peaks and Bernal Heights lots, we stage materials at the street and use roof brackets and walk boards rather than dragging panels across finished surfaces.

1. We pull permits and confirm historic-district or HOA design review requirements before ordering panels.
2. We tear off the old roofing and haul it away the same day, then inspect the decking for rot, delamination, and failed fasteners.
3. We repair or replace damaged sheathing and refasten loose deck boards to the framing.
4. We install underlayment, ice-and-water membrane at valleys and penetrations, and new edge metal.
5. We set the new metal panels or shingles, then flash chimneys, skylights, and sidewalls with metal, not tar.
6. We walk the roof with you, hand over the permit sign-off, and leave the gutters clear.

Every replacement ends with a water test at the flashings and a written summary of what we found under the old roof.

Key info: On a Forest Hill home with a low-slope roof hidden behind a parapet, we found rotted fascia behind the false front that no one had seen from the ground. We repaired it before the new panels went on, which is the only time that work is cheap.

If your roof is still sound and you want to avoid a full tear-off, ask about metal roof over shingles. If you are weighing panel styles, our standing seam metal roofing page covers the concealed-fastener option most homeowners ask about.

Replacement Approaches We Use Across San Francisco

Not every house wants the same metal system. A Sunset row house with a flat roof and a Marina home with red clay tile call for different products and different flashing details. Here is how we match the approach to the building.

We match the profile and color to the house and to any design review rules before we order a single panel.

Metal Roof Replacement Cost in San Francisco: What to Expect

Pricing starts from $9 per square foot for a straightforward replacement on an accessible roof. That figure is a starting point, not a quote. A flat Sunset row house with easy street access sits near the bottom of the range. A steep Twin Peaks hillside lot with a bay window, two chimneys, and a parapet pushes toward the top. Square footage, roof pitch, panel type, decking condition, and the number of penetrations all move the number.

Older San Francisco homes almost always hide something under the old roof: rotted fascia, undersized sheathing, or flashing that was tarred over instead of replaced. We price those repairs as we find them and show you photos before we proceed. Getting two or three written estimates is smart, and so is asking each contractor what happens if the decking is bad. Our full pricing overview breaks down the ranges by system.

We never suggest a deductible could be waived or absorbed. If storm damage is involved, we document the roof for your insurance claim, and coverage is the carrier's decision.

Metal Roof Replacement Near Me: How to Vet a Contractor in San Francisco

Hiring for a metal roof replacement near San Francisco means checking more than a license number. You want a crew that knows historic-district design review, HOA color and profile rules, and how to pull the right permit from the city. Ask for the license, the insurance certificate, and three local references from jobs similar to yours. Ask whether they handle the tear-off and haul-away themselves or subcontract it.

• Confirm the contractor is licensed and carries both liability and workers' compensation insurance, and request the certificate in writing.
• Get two or three itemized estimates so you can compare decking repair allowances, panel type, and flashing details.
• Ask for references from San Francisco jobs, ideally in your district or a similar building type.
• Confirm who pulls the permit and who handles historic-district or HOA design review approvals.
• Ask what the crew does to keep the house dry overnight during tear-off.
