Free Roof Program: Costs, Lifespan and Alternatives

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

Yes. Western Addition is about 340 miles from our Santa Monica yard, and we work it alongside Japantown, Hayes Valley and San Francisco on the same routes.

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

Western Addition 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.

Yes. Low-slope sections on Western Addition 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.

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

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 Western Addition property, depending on size, pitch and how much deck needs replacing. Nothing is left open overnight.
