Bayview Torch Down Modified Bitumen Roofing

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.

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.

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.

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.

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.

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

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.
