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, 12 of them registered in San Mateo. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median San Mateo license has been held 23 years, and the longest-standing one dates to 1968. 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: 12 of San Mateo's 12 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 do I check a roofer's license in California?
