Asphalt Shingle: Costs, Lifespan and Alternatives

We start at the flashings, check the deck from inside the attic, and photograph every elevation. On a Castro property we pay particular attention to dried-out underlayment and attic temperature.

About 339 miles from our Santa Monica yard, so work in Castro is planned as a scheduled trip rather than a same-day call, with planned work booked around the weather.

Yes. Claims on Castro properties turn on documentation taken before anything is tarped or cleared, and we work alongside the adjuster rather than around them.

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.

Yes. Low-slope sections on Castro buildings need a membrane or coating system rather than shingle laid flatter than it is rated for, and they are quoted separately from the pitched roof.

Yes. Castro is about 339 miles from our Santa Monica yard, and we work it alongside Noe Valley, Twin Peaks and Cole Valley on the same routes.

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

A full replacement in Castro is permitted and inspected through the San Francisco Department of Building Inspection. Small repairs generally are not, but the layer count and assembly are checked on any permitted job.
