Resealing penetrations on a Mission Bay roof covering every few years is the cheapest work anyone will ever do on the building. Two visits a year keeps a Mission Bay roof covering honest: clear the valleys and gutters in advance of the rains, and look over the flashings after the first heavy storm. Keeping a dated maintenance file on a Mission Bay property pays for itself the first time a claim is questioned. That is as true in Mission Bay as anywhere in San Francisco County. Put simply, trimming back branches over a Mission Bay roof removes the debris that holds water against the covering and shortens its service life.

Realistically, streets in Mission Bay that were built out together tend to require roofs together, which is why one re-roof often brings three more on the same block. Nearly all roofs in Mission Bay fall into three groups: original coverings near the end of their life, replacements from the last two decades, and low-slope sections added later. Put simply, second-storey additions in Mission Bay create a junction between old and new roof covering that requires proper flashing rather than sealant. San Francisco County is no different.
