Ventura County roofing licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 159 active C-39 roofing licenses in Ventura County, 34 of them registered in Simi Valley. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Simi Valley license has been held 10 years, and the longest-standing one dates to 1975. 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: 32 of Simi Valley's 34 licenses (94.1%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 158 of the county's 159 licenses carry the same $25,000 bond California sets by statute. 21 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.

Does California license roofers?

Only CLEAR, unexpired licenses appear here.
How do I check a roofer's license in California?
Every listing above shows its CSLB license number.
