Metal Roof Repair in San Francisco: When the Panels Start Talking
San Francisco metal roofs take a beating that most of the country never sees. Between the Pacific salt air rolling through the Sunset, atmospheric-river storms dumping rain on Victorian and Edwardian homes, and hillside houses stepping up Twin Peaks, the metal panels, fasteners, and flashing on your roof are under constant pressure. If you are hearing rattles, seeing rust streaks, or finding water stains on a ceiling, you need metal roof repair in San Francisco before the next storm finds that weak point.
We have been repairing metal roofs in this city since 2009, and we are a Metal Roofing Alliance Member. We know the difference between a screw that backed out on a 1930s stucco row house in the Richmond and a seam that failed on a modern standing seam roof in Bernal Heights. Call (628) 356-4308 and we will get a look at it. You can also read about our dedicated leak repair service here if water is already coming in.
Why Metal Roof Repair Matters More in San Francisco Than Anywhere Else
The building stock here is the reason. Rows of 1880s to 1910s Victorians and Edwardians with ornate cornices and bay windows sit next to 1920s Spanish Revival homes in the Marina and 1950s stucco row houses in the Sunset. Many of these roofs are flat or low-slope, hidden behind parapets and false fronts in Pacific Heights and the Haight. When metal panels or flashing fail on those roofs, water does not just drip. It pools, it tracks along framing, and it shows up three rooms away.
- Salt air corrosion eats at cut edges, fastener heads, and panel laps on homes from the Outer Richmond to Sausalito.
- Wind-driven rain from winter storms pushes water past failed sealant and loose flashing on hillside homes in Bernal Heights and Diamond Heights.
- Tree debris from Monterey cypress, eucalyptus, and coast live oak traps moisture and clogs valleys on redwood-shaded homes in Marin and the Oakland and Berkeley Hills.
- Thermal movement on long standing seam panels loosens fasteners and opens seams on modern infill roofs.
None of these failures wait for a convenient time. A small repair in October is a fraction of the cost of a rotted deck and interior drywall repair in January.
Key info: On a 1940s stucco row house in the Sunset, we routinely find that the original metal drip edge has rusted through behind the stucco. Water runs back under the roof edge and rots the fascia. That is a repair we can catch in an afternoon if we see it before the rainy season.

How We Diagnose and Repair Metal Roofs in San Francisco
We start on the roof, not in the truck. A proper repair begins with walking the panels, checking every fastener, probing seams and penetrations, and looking at the flashing where the roof meets chimneys, skylights, and parapet walls. On a steep Victorian in Noe Valley or a hillside home off Twin Peaks, that means setting up safe access before anyone touches a tool. We photograph what we find and show you the problem before we quote the fix.
- We inspect the full roof surface, fasteners, seams, valleys, and all flashing details.
- We identify the source of the leak or damage and separate it from secondary staining or debris.
- We replace corroded or punctured panels, or reseal and re-fasten where the metal is still sound.
- We re-flash chimneys, skylights, and wall intersections with metal that matches the existing roof.
- We test the repair with water before we leave and document the work for your records.
If the damage is isolated to fasteners, we handle that as a dedicated job. You can see our screw replacement and re-fastening service here.
Key info: A homeowner in Pacifica called us after a storm because water was pouring through a skylight. The panels were fine. The skylight curb flashing had been sealed with caulk instead of metal, and the caulk had failed. We rebuilt the flashing in half a day and stopped a leak that three previous caulk jobs had only hidden.
Repair Approaches We Use on San Francisco Metal Roofs
Not every metal roof repair is the same. A screw-down corrugated roof on a Richmond district row house needs different treatment than a standing seam roof on a modern infill in the Mission. Here is how we match the approach to the roof.
| Approach | Description | Best for |
|---|---|---|
| Panel replacement | We cut out the damaged panel and install a matching replacement with new fasteners and sealant at the laps. | Punctures, large dents, or panels with corrosion that has eaten through the metal. |
| Seam and fastener repair | We reseal open seams and replace backed-out or corroded screws with oversized fasteners and sealing washers. | Standing seam and exposed fastener roofs with loose seams or popped screws. |
| Flashing rebuild | We remove failed caulk and old flashing and install new metal flashing at chimneys, skylights, and walls. | Leaks at penetrations, especially on older homes where caulk has been the only fix for years. |
| Spot coating and rust treatment | We treat surface rust, prime the metal, and apply a compatible coating to stop corrosion from spreading. | Light surface rust on coastal roofs where full panel replacement is not yet needed. |
| Full panel section replacement | We replace an entire run or slope where damage is too widespread for spot repairs. | Storm-damaged or heavily corroded sections on roofs with good underlying structure. |
Each of these approaches is a repair, not a replacement. If the roof is past the point where repair makes sense, we will tell you straight and walk you through the alternatives.
Metal Roof Repair Cost in San Francisco: What to Expect
Metal roof repair in San Francisco starts at From $450 for a straightforward job such as replacing a few fasteners, resealing a seam, or treating a small rust spot. That figure covers the basics: access, labor, and standard materials. From there, the price moves based on what we find when we get on the roof.
The biggest cost drivers are access and scope. A steep hillside home in Diamond Heights or a Victorian with a complex roofline takes more setup than a flat roof in the Sunset. Replacing a single panel is different from rebuilding chimney flashing. If the repair is on a tall building or requires scaffolding, that adds cost. If the damage is widespread, we will show you the photos and explain why a larger repair makes more sense than patching.
We recommend getting two or three estimates for any metal roof repair. It is the best way to understand the scope and confirm you are getting a fair price. You can review our full pricing overview here for more detail on how we structure repair costs.
What to Look for When Hiring a Metal Roofing Contractor Near San Francisco
Hiring the right contractor for metal roof repair near San Francisco means asking a few direct questions before anyone gets on your roof. Start with licensing and insurance. A legitimate contractor carries a state license and general liability and workers compensation coverage. Ask for the certificate and verify it.
Get at least two or three written estimates that spell out the scope, materials, and timeline. Ask for references from jobs in your neighborhood or a similar roof type. If your home is in a historic district or under HOA design review, confirm the contractor understands the rules before work begins. Permits may be required depending on the scope and jurisdiction, so ask who pulls the permit and who handles inspection.
