Roofer in San Francisco

We cover San Francisco across San Francisco County, including Hayes Valley, Tenderloin and South of Market, and the rest of the service area listed on the site.

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

Size, pitch, layer count and deck condition drive the number on any San Francisco roof. The line that moves is deck repair, so it belongs in the San Francisco quote at a rate per sheet rather than as an allowance.

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

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

Yes. Low-slope sections on San Francisco 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.

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