Free Roof Program: Costs, Lifespan and Alternatives

In coastal 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 start at the flashings, check the deck from inside the attic, and photograph every elevation. On a Sunset District property we pay particular attention to corroded fixings and lifted edge metal.

A full replacement in Sunset District 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.

Granules in the gutters, curling tabs, repeat stains in the same ceiling after every storm, and soft spots underfoot. In Sunset District, fasteners and flashing corrode before the covering does, so fixing specification matters more here than material choice.

Sunset District sits in San Francisco County and takes salt air off the water, long marine-layer mornings and slow-drying north slopes. In practice that means fasteners and flashing corrode before the covering does, so fixing specification matters more here than material choice.

Yes. Sunset District is about 340 miles from our Santa Monica yard, and we work it alongside Parkside, Forest Hill and West Portal on the same routes.

Yes. Low-slope sections on Sunset District 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 Sunset District roof with life left and one localised failure. Once the covering is past its service life, repairs buy months and a replacement buys decades.
