Standing Seam & Metal Roofing in Castro

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.

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.

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

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.

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.

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.

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.

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.
