Roof Replacement on a San Francisco Roof
Replacing a roof in San Francisco is a tear-off-to-walk-through job we keep entirely in-house — no subcontracted crews. We photograph the existing conditions, strip the old roof to the deck, and inspect every sheet of decking before a single new shingle goes on, because what's under the old roof is what determines how long the new one lasts. From there it's manufacturer-spec underlayment, ventilation corrected to code, the system you chose installed by our own crew, full debris haul-off, and a final walk-through with you on the ground.
San Francisco's wind exposure drives our fastening and edge-detail choices on a replacement — enhanced nailing patterns and sealed edges are what keep a new roof on through the gusts.
- Pre-existing-condition photos before tear-off
- Full deck inspection and dry-rot repair
- Code-correct ventilation, not just new shingles
- San Francisco County permit pulled and inspection scheduled

What San Francisco Roofs Are Up Against
Every roof in San Francisco answers to the same forces: a Coastal fog, cool summers (55–65°F), wet winters with 20" annual rainfall, and an aging housing stock dominated by Victorian, Edwardian, Mid-Century Modern, high-density flat-roof condos. The specific local stressors that decide how long a roof actually lasts here: Persistent marine fog and moisture accelerate granule loss on asphalt shingles. High winds in exposed neighborhoods like Twin Peaks and the Outer Sunset require secure fastening patterns. Salt air near the bay accelerates metal corrosion without protective coatings. We've spent enough time on San Francisco roofs to know which failure modes show up first, and we plan roof replacement around them rather than discovering them halfway through the job.
Roof Replacement in San Francisco — FAQs
How long does a roof replacement take in San Francisco?
A typical single-family San Francisco replacement runs two to four working days, weather permitting. Tile and steep or cut-up roofs take longer; a simple ranch with good access goes quicker. You get a firm schedule in the written estimate, not a vague window.
Do you pull the permit for a San Francisco roof replacement?
Yes. Every full replacement in San Francisco is permitted through the San Francisco County building department and inspected — we handle the pull, line-item the fees, and schedule the inspection. Unpermitted roofing work can void your homeowner's insurance and create problems at resale.
What's the best roofing material for a San Francisco home?
It depends on your roof's pitch, exposure, and the original assembly — there's no single answer. For most San Francisco homes a Class 4 architectural asphalt shingle is the value sweet spot; tile and standing-seam metal make sense where the structure and budget support a 40–50 year horizon. We walk the roof and put the recommendation in writing.
