Castro Commercial Roofing

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.

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

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.

We cover Castro across San Francisco County, including Noe Valley, Twin Peaks and Cole Valley, and the rest of the service area listed on the site.

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.

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

Castro 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.

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