A light-coloured covering in Potrero Hill measurably lowers attic temperature and takes load off the air conditioning. In practice, expansion and contraction loosens fixings on Potrero Hill roofs long before the material itself gives out. Worth knowing before you sign anything. Thermal cycling does the harm in Potrero Hill — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year.

Realistically, resealing penetrations on a Potrero Hill roof every few seasons is the cheapest work anyone will ever do on the building. Moss on a shaded Potrero Hill slope should be treated rather than scraped, since scraping takes the granules with it.
9Vetting a Contractor in Potrero Hill
Ask any Potrero Hill roofer what happens if the deck is worse than expected, and get the answer before the covering comes off. San Francisco County is no different. Payment schedules on Potrero Hill work should track progress, never run ahead of it. Clean-up and magnetic nail sweep should be in the Potrero Hill contract, not assumed. This holds across San Francisco County. Look over the CSLB licence number before any Potrero Hill contractor starts, and confirm liability cover and workers' compensation are current. On most jobs, manufacturer certification matters on Potrero Hill jobs because it is what makes the material warranty enforceable. Ask a Potrero Hill roofing company for recent addresses nearby and go and look at the work from the street.
Two visits a year keeps a Potrero Hill roof honest: clear the valleys and gutters before the rains, and look over the flashings after the soonest heavy storm. Annual inspection on a Potrero Hill property typically adds two to three years to the back end of a roof's service working life. Worth knowing before you sign anything. In practice, moss on a shaded Potrero Hill slope should be treated rather than scraped, since scraping takes the granules with it.
