9What the Weather Does to a Potrero Hill Roof
Thermal cycling does the damage in Potrero Hill — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. That is as true in Potrero Hill as anywhere in San Francisco County. Realistically, roof coverings in Potrero Hill bake. Asphalt loses its oils, membranes lose their plasticisers, and sealant shrinks back from every flashing. Attic ventilation on a Potrero Hill property is not optional — trapped heat cooks the covering from underneath. We see it on Potrero Hill roofs every week. Put simply, attic temperatures in Potrero Hill drive shingle life as much as the weather above does, which is why ventilation matters more here than the brochure suggests. Tile underlayment in Potrero Hill dries out and goes brittle while the tile above it still looks new from the street.
the San Francisco Department of Building Inspection handles the paperwork for roofing work in Potrero Hill, and a licensed contractor pulls it as part of the work rather than leaving it to the owner. Structural work on a Potrero Hill roof triggers a separate review beyond the roofing permit itself. Commercial work in Potrero Hill usually involves more review than residential and a longer lead time.
