Residential Roofing: Costs, Lifespan and Alternatives

Presidio 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.

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

Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In Presidio that matters most because fasteners and flashing corrode before the covering does, so fixing specification matters more here than material choice.

Yes. Presidio is about 342 miles from our Santa Monica yard, and we work it alongside Richmond District, Sea Cliff and Pacific Heights on the same routes.

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

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

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

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.
