What this record tells you

One Source Building Inc. holds Florida licence CCC1327703, a CCC classification which authorises work as a certified/registered roofing contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2006, which makes it a long-held licence for the trade in this area. Roughly 15% of the 719 active roofing licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2016. That is 20 years of continuous licensure.

One Source Building Inc. is one of 393 active roofing licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. John Walton Jr Nichols additionally holds 1 other active Florida licence in our records, which can indicate a contractor qualified across more than one trade or entity.

The licence is recorded as expiring on 08/31/2026. Florida licences renew on a fixed cycle, and a licence that is not renewed moves to delinquent status — which is why the expiry date matters if you are planning work close to that date. Confirm the current status on the state portal before signing a contract.
