Synthetic Composite: Costs, Lifespan and Alternatives

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

Western Addition 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 Western Addition, asphalt dries out and sealant pulls back from penetrations years before the field wears through.

We cover Western Addition across San Francisco County, including Japantown, Hayes Valley and San Francisco, and the rest of the service area listed on the site.

One to three days on a typical Western Addition property, depending on size, pitch and how much deck needs replacing. Nothing is left open overnight.

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.

About 340 miles from our Santa Monica yard, so work in Western Addition is planned as a scheduled trip rather than a same-day call, with planned work booked around the weather.
