Torch Down Modified Bitumen Roofing in San Francisco

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.

Check the licence, liability cover and workers' compensation, then ask any San Francisco contractor what happens if the deck is worse than expected — and get that answer in writing before the covering comes off.

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.

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.

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.

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.

Yes. San Francisco is about 339 miles from our Santa Monica yard, and we work it alongside Hayes Valley, Tenderloin and South of Market on the same routes.

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.
