San Diego County roofing licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 400 active C-39 roofing licenses in San Diego County, 38 of them registered in El Cajon. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median El Cajon license has been held 17 years, and the longest-standing one dates to 1970. 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: 29 of El Cajon's 38 licenses (76.3%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 398 of the county's 400 licenses carry the same $25,000 bond California sets by statute. 36 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.
