Photographs with dates are part of every Presidio inspection, given that an undocumented claim gets read as wear and tear by any adjuster. As a rule, flashing at the wall junction is checked first on any Presidio inspection, since that is where most ceiling stains originate. Deck fastener pull-through is checked on older Presidio roofs, since the sheathing often lets go ahead of the shingle does.
