Acrylic Roof Coating: Costs, Lifespan and Alternatives

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.

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

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

Yes. Low-slope sections on Tenderloin 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.

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

A full replacement in Tenderloin 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.

We cover Tenderloin across San Francisco County, including South of Market, Nob Hill and San Francisco, and the rest of the service area listed on the site.

Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In Tenderloin that matters most because asphalt dries out and sealant pulls back from penetrations years before the field wears through.
