Sonoma 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 Sonoma County, 6 of them registered in Windsor. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Windsor license has been held 8 years, and the longest-standing one dates to 2000. 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 Windsor's 6 licenses (83.3%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 89 of the county's 90 licenses carry the same $25,000 bond California sets by statute. 10 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.
