San Mateo County roofing licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 90 active C-39 roofing licenses in San Mateo County, 17 of them registered in Redwood City. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Redwood City license has been held 10 years, and the longest-standing one dates to 1996. California law requires workers' compensation cover for C-39 licensees, so it is a legal baseline rather than a way to tell two contractors apart: 17 of Redwood City's 17 licenses (100.0%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 88 of the county's 90 licenses carry the same $25,000 bond California sets by statute. 3 county licenses reach their expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.

How many licensed roofers are there in Redwood City?

Does California license roofers?
Yes.

Only CLEAR, unexpired licenses appear here.
How do I check a roofer's license in California?
Every listing above shows its CSLB license number. CSLB cannot link straight to a record, so open its license lookup and type the number in: it shows status, expiration, the contractor bond and workers' compensation cover, which California requires of C-39 licensees and 17 of Redwood City's 17 currently carry. 3 San Mateo County licenses expire within 90 days.
