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, 47 of them registered in Oakland. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Oakland license has been held 7 years, and the longest-standing one dates to 1955. 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: 47 of Oakland's 47 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.
Roofers in Oakland: common questions
How many licensed roofers are there in Oakland?

Does California license roofers?
Yes. California licenses contractors by classification, and C-39 is the CSLB classification that authorises this work, unlike Texas, which licenses no roofing contractors at all. 47 active C-39 roofing licenses are registered in Oakland and 194 across Alameda County, the longest-standing issued in 1955. Only CLEAR, unexpired licenses appear here.
How do I check a roofer's license in California?
Every listing above shows its CSLB license number. CSLB cannot link straight to a record, so open its license lookup and type the number in: it shows status, expiration, the contractor bond and workers' compensation cover, which California requires of C-39 licensees and 47 of Oakland's 47 currently carry. 15 Alameda County licenses expire within 90 days.
