San Francisco County is no different.
A Outer Mission inspection should end with a written report and photographs, not a verbal summary and a price. Deck fastener pull-through is checked on older Outer Mission roof coverings, since the sheathing often fails before the shingle does. On most jobs, valley condition is the single best indicator of how a Outer Mission roof has been maintained.
