Roof Installation: Process, Costs and What to Expect

Granules in the gutters, curling tabs, repeat stains in the same ceiling after every storm, and soft spots underfoot. In Outer Mission, asphalt dries out and sealant pulls back from penetrations years before the field wears through.

We start at the flashings, check the deck from inside the attic, and photograph every elevation. On an Outer Mission property we pay particular attention to dried-out underlayment and attic temperature.

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

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.

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

Outer Mission 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.

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

We cover Outer Mission across San Francisco County, including Oceanview, Ingleside and Crocker-Amazon, and the rest of the service area listed on the site.
