TPO Membrane: Costs, Lifespan and Alternatives

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

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

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

Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In Hayes Valley 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.

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

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

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