Roof Repair for Storm & Wind Damage: Process, Costs and What to Expect

A full replacement in Bayview 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.

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

Bayview 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.

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

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

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

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

Pitch and exposure decide it before appearance does. Given inland conditions in Bayview, reflective coverings and real attic ventilation make the biggest difference.
