Permit timeline
Across San Francisco, a roofing permit stays open about 28 days, from permit to final inspection
This is not how long the crew works at your home: most of it is waiting for the inspection. Ask them how many days the work takes. The permit itself is usually issued the same day. How long roofing jobs take.
