Supplements are normal on Potrero Hill claims once the covering is off and the deck is visible, and they should be raised with evidence rather than argued later.
Dry offshore winds reach Potrero Hill through autumn, lifting shingle tabs and ridge caps in the direction roofs are least lapped to resist. Potrero Hill gets its rainfall in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. As a rule, afternoon sun on a west-facing Potrero Hill slope ages that side years ahead of the rest of the roof.
9Keeping a Potrero Hill Roof in Service
In practice, clearing the Potrero Hill gutters in late autumn prevents most of the damage the soonest storm would otherwise cause. This holds across San Francisco County. Annual inspection on a Potrero Hill property typically adds two to three years to the back end of a roof's service life. In practice, trimming back branches over a Potrero Hill roof removes the debris that holds damp against the covering and shortens its working life. Loose ridge caps on a Potrero Hill roof are a five-minute fix before the winds and a much larger one after. Worth knowing before you sign anything. Drainage is the cheapest maintenance on any Potrero Hill building — blocked outlets cause more damage here than the storms themselves.
Put simply, a Potrero Hill roof quoted without anyone looking in the attic is a quote based on half the information. As a rule, a Potrero Hill estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately. San Francisco County is no different. The variable line on any Potrero Hill quote is deck patch, and it should be priced per sheet in writing rather than hidden in an allowance.
