Clearing the Potrero Hill gutters in late autumn prevents nearly all of the damage the first storm would otherwise cause. Trimming back branches over a Potrero Hill roof removes the debris that holds moisture against the covering and shortens its working life. On most jobs, two visits a year keeps a Potrero Hill roof honest: clear the valleys and gutters ahead of the rains, and check the flashings after the first heavy storm. This holds across San Francisco County.
Put simply, the San Francisco Department of Building Inspection handles the paperwork for roofing work in Potrero Hill, and a licensed roofing company pulls it as part of the job rather than leaving it to the property owner. In practice, fire-zone properties around Potrero Hill carry assembly requirements that the permit will inspect against. Put simply, reroofing over existing layers in Potrero Hill is limited by code, and the layer count is checked at inspection.
