Standing Seam & Metal: Costs, Lifespan and Alternatives

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

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

Granules in the gutters, curling tabs, repeat stains in the same ceiling after every storm, and soft spots underfoot. In San Gabriel, 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 a San Gabriel property we pay particular attention to dried-out underlayment and attic temperature.

A full replacement in San Gabriel is permitted and inspected through the San Gabriel building department. Small repairs generally are not, but the layer count and assembly are checked on any permitted job.

Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In San Gabriel that matters most because asphalt dries out and sealant pulls back from penetrations years before the field wears through.

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.

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