Realistically, roof pitch across Portola varies enough that the right material on one street is the wrong one two blocks away. Realistically, original decking on older Portola homes is often skip sheathing, which changes what can be laid over it. This holds across San Francisco County.
As a rule, a Portola estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately. On most jobs, seasonal demand in Portola affects scheduling more than price, but booking ahead of the rains helps both. A Portola estimate that comes in far below the others is in most cases missing the flashing, the permit or the disposal.
