Flashings at the chimney on an older Potrero Hill house in most cases need attention well ahead of the covering does. Realistically, keeping a dated maintenance file on a Potrero Hill property pays for itself the first time a claim is questioned. That is as true in Potrero Hill as anywhere in San Francisco County. A Potrero Hill roof covering with working drainage outlasts an identical roof without it by years.
As a rule, written, itemised estimates let Potrero Hill owners compare bids properly rather than guessing at what is included. Put simply, warranty terms affect the real cost of a Potrero Hill roof more than the headline figure does. A Potrero Hill estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately.
