Moss on a shaded Potrero Hill slope should be treated rather than scraped, since scraping takes the granules with it. San Francisco County is no different.
In practice, photographs taken ahead of any tarping on a Potrero Hill property are the nearly all valuable evidence in the whole claim. The majority of Potrero Hill claims that give out do so since the harm was cleaned up or patched ahead of anyone photographed it. Realistically, a Potrero Hill adjuster works from the scope in front of them, which is why the contractor's report has to be thorough.
9Reading a Potrero Hill Roof by Its Era
Roof pitch across Potrero Hill varies enough that the right material on one street is the wrong one two blocks away. Housing stock in Potrero Hill runs across several eras, and each one brings its own roof covering. What sits above the ceiling usually tells you when the building went up. Most roofs in Potrero Hill fall into three groups: original coverings near the end of their life, replacements from the last two decades, and low-slope sections added later. Realistically, solar arrays on Potrero Hill roof coverings complicate replacement, and the panel age rarely matches the roof age. We see it on Potrero Hill roofs every week. Put simply, a Potrero Hill property commonly carries more than one roof type — a pitched main house in one material and a flatter garage or addition in another.
Trimming back branches over a Potrero Hill roof covering removes the debris that holds moisture against the covering and shortens its service life. As a rule, a maintenance record on a Potrero Hill roof also helps at claim time, because it shows the failure was sudden rather than neglected. On most jobs, most Potrero Hill roof coverings that fail early fail at a penetration someone could have resealed for a few hundred dollars.
