Asphalt Shingle: Costs, Lifespan and Alternatives

We cover San Diego across San Diego County, including Coronado, National City and Chula Vista, and the rest of the service area listed on the site.

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

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.

Repair makes sense on a San Diego roof with life left and one localised failure. Once the covering is past its service life, repairs buy months and a replacement buys decades.

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

About 119 miles from our Santa Monica yard, so work in San Diego is planned as a scheduled trip rather than a same-day call, with planned work booked around the weather.

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

San Diego sits in San Diego 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.
