Realistically, the permit record for a West Portal property is public, which is how a buyer's inspector checks the roof was done properly. On most jobs, codes change, and the San Francisco Department of Building Inspection applies the version current on the day the permit issues, which is one reason a West Portal quote should state the assembly being installed. San Francisco County is no different.
