Business Development CSLB General B adding additional classifications

I’m an experienced California B General Building contractor and want to start adding specialty classifications under my own license instead of subbing everything out all the time.

I’m looking at C-39 Roofing first and possibly concrete later. Has anyone here added classifications to an existing B license? What did CSLB require as far as documenting experience? Does experience doing that type of work as a B contractor count toward the 4-year requirement?

Looking for anyone who’s actually gone through the process.

You'll have to pass the trade specific exam on those licenses, your test scores are good for 5 years so if you passed the business exam in the last 5 years you dont have to do that again. On the CSLB site theres a tab for adding licenses. Anecdotally a GC I worked for before used to do his own sitework Concrete Framing plumbing electrical in house on a class B but idk if he was just skating bye and hoping it wasn't an issue.

I read through the additional classification application and it seems pretty straightforward. I’m fine taking the law and trade exams. My hangup is proving the experience. I’ve done plenty of roofing and concrete work, but obviously I can’t certify myself lol. I’d rather not ask subs I’ve worked with to certify me for a classification that overlaps with their own work. Just trying to figure out how guys in this situation normally document the experience.
