Drainage is the cheapest maintenance on any Outer Mission building — blocked outlets cause more damage here than the storms themselves. Two visits a year keeps a Outer Mission roof covering honest: clear the valleys and gutters in advance of the rains, and inspect the flashings after the earliest heavy storm.
In practice, financing makes sense on a Outer Mission roof that is actively failing; it rarely makes sense on one with seasons of working life left. This holds across San Francisco County. Put simply, square footage is only half the cost of a Outer Mission roof; pitch, access and layer count move the number as much. That is as true in Outer Mission as anywhere in San Francisco County. Budgeting a Outer Mission replacement a few seasons out costs nothing and removes the pressure of choosing a contractor during a storm. It is the same story on most Outer Mission streets.
