Many Potrero Hill properties carry a covering chosen for price rather than climate, and it shows in how early it fails.

Lightweight tile gives Potrero Hill owners the look without the structural upgrade older framing would otherwise require. It is the same story on most Potrero Hill streets. Reclaimed tile can be matched on Potrero Hill heritage roof coverings, but the underlayment beneath it should always be new. Metal has grown in Potrero Hill for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. Worth knowing before you sign anything. Realistically, concrete tile suits Potrero Hill buildings designed for the weight; laying it on framing that was not is a structural question first.
We look over ventilation on every Potrero Hill job, given that a roof that cannot breathe will not reach its rated life. Deck fastener pull-through is checked on older Potrero Hill roofs, since the sheathing commonly fails ahead of the shingle does. San Francisco County is no different. Granule loss in the gutters is the earliest honest signal on a Potrero Hill shingle roof, and it shows up years ahead of a ceiling stain does.
