In practice, the variable line on any Portola estimate is deck make good, and it should be priced per sheet in writing rather than hidden in an allowance. San Francisco County is no different.

Two visits a year keeps a Portola roof honest: clear the valleys and gutters in advance of the rains, and look over the flashings following the first heavy storm. On most jobs, checking the attic after the earliest heavy rain in Portola finds leaks while they are still stains rather than harm.
