TPO Membrane Roofing in Bayview

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

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.

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.

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.

Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In Bayview that matters most because 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 Bayview property we pay particular attention to dried-out underlayment and attic temperature.

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.
