Realistically, two visits a year keeps a Twin Peaks roof honest: clear the valleys and gutters before the rains, and check the flashings following the first heavy storm. Runoff arrives fast in Twin Peaks. Slope above the property means drainage has to cope with volume rather than just rainfall. That is as true in Twin Peaks as anywhere in San Francisco County.

Additions and conversions are common in Twin Peaks, and the joint between the original roof covering and the newer section is where most leaks begin. Snow is not the issue in Twin Peaks, but overnight frost on north slopes slows drying through winter. San Francisco County is no different.

Garage and patio roofs in Twin Peaks are frequently lower slope than the house and require an entirely different system. That is as true in Twin Peaks as anywhere in San Francisco County.

In practice, gutter guards earn their keep in Twin Peaks where needle and leaf load is constant rather than seasonal.

Ember risk shapes roofing decisions in Twin Peaks: class A assemblies, closed eaves, and no gaps at the ridge where embers can enter. This holds across San Francisco County. As a rule, trimming back branches over a Twin Peaks roof covering removes the debris that holds moisture against the covering and shortens its life.
