Asphalt Shingle Roofing in Excelsior

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

Excelsior sits in San Francisco County and takes long dry heat, hard thermal cycling and rain that arrives in a few concentrated storms. In practice that means asphalt dries out and sealant pulls back from penetrations years before the field wears through.

Granules in the gutters, curling tabs, repeat stains in the same ceiling after every storm, and soft spots underfoot. In Excelsior, asphalt dries out and sealant pulls back from penetrations years before the field wears through.
