Bayview TPO Membrane Roof Repair

Yes. Low-slope sections on Bayview buildings need a membrane or coating system rather than shingle laid flatter than it is rated for, and they are quoted separately from the pitched roof.

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.

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.

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.

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

Yes. Bayview is about 336 miles from our Santa Monica yard, and we work it alongside Portola, Visitacion Valley and Bernal Heights on the same routes.

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.

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