Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In Hayes Valley that matters most because asphalt dries out and sealant pulls back from penetrations years before the field wears through.

In inland conditions, composition shingle runs roughly fifteen to twenty-five years, tile underlayment twenty to twenty-five, and coatings seven to fifteen depending on the system.

Pitch and exposure decide it before appearance does. Given inland conditions in Hayes Valley, reflective coverings and real attic ventilation make the biggest difference.
