2Roof Age Across Potrero Hill

A Potrero Hill property often carries more than one roof type — a pitched main house in one material and a flatter garage or addition in another.

8Housing Stock and Roof Types in Potrero Hill

Realistically, streets in Potrero Hill that were built out together tend to need roof coverings together, which is why one re-roof frequently brings three more on the same block. In practice, roof covering age across Potrero Hill clusters around the decades when the area filled in, which means whole streets reach the end of their covering within a few years of each other. On most jobs, roof pitch across Potrero Hill varies enough that the right material on one street is the wrong one two blocks away. San Francisco County is no different. Original decking on older Potrero Hill homes is often skip sheathing, which changes what can be laid over it. Worth knowing before you sign anything.

Realistically, expansion and contraction loosens fixings on Potrero Hill roof coverings long before the material itself gives out. Worth knowing before you sign anything. In practice, 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. Roof covering surface temperatures in Potrero Hill routinely run well above the air reading, and every material on the roof feels it. Sealant is the soonest casualty in Potrero Hill; it shrinks, cracks and pulls away from every penetration within a few seasons. It is the same story on most Potrero Hill streets. Afternoon sun on a west-facing Potrero Hill slope ages that side years ahead of the rest of the roof.
