Contra Costa County roofing licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 156 active C-39 roofing licenses in Contra Costa County, 37 of them registered in Concord. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Concord license has been held 20 years, and the longest-standing one dates to 1929. 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: 35 of Concord's 37 licenses (94.6%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 155 of the county's 156 licenses carry the same $25,000 bond California sets by statute. 11 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?
Every listing above shows its CSLB license number.
