Alameda County roofing licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 194 active C-39 roofing licenses in Alameda County, 5 of them registered in Union City. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Union City license has been held 0 years, and the longest-standing one dates to 1995. 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: 5 of Union City's 5 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: 193 of the county's 194 licenses carry the same $25,000 bond California sets by statute. 15 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.
