Sunset District Flat & Low-Slope Roof Repair

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.

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

About 340 miles from our Santa Monica yard, so work in Sunset District is planned as a scheduled trip rather than a same-day call, with planned work booked around the weather.

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.

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

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.

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

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.
