What’s the California C39 License All About?

Ever thought about what it takes to become a licensed roofing contractor in California? It all starts with the California C39 License. This license isn’t just another piece of paper—it’s your ticket to legally install, repair, and maintain roofs, protecting homes and other structures from the elements. Roofing contractors with a C39 license focus on sealing, waterproofing, and weatherproofing to prevent water from sneaking into places it shouldn’t. Without this license, you can’t legally take on roofing jobs in the state. Makes sense, right?

To earn this license, you’ll go through a structured process. You don’t just sign up and call it a day! You’ll need to pass two state exams—the Law & Business exam (which covers contracting basics and legal requirements) and the C39 Trade exam (focused on the nitty-gritty of roofing). If you’re serious about diving into the industry, the California C39 License is non-negotiable.

How Do You Get a California C39 License?

So you’re ready to take the plunge—what’s next? Getting your C39 license isn’t something you do overnight. Here’s the roadmap:

  1. Experience: Do you have four years of hands-on roofing experience? This could be as a journeyman, supervisor, contractor, or foreman. That’s the foundation.
  2. Application: You’ll need to submit an official application to the California Contractors State License Board (CSLB). You can do this online if you’re tech-savvy, but old-school mail works too.
  3. Pass the Exams: This is where the rubber meets the road. You’ll need to pass two tests:
    • Law & Business Exam: Covers the rules, laws, and business basics every contractor should know.
    • C39 Trade Exam: Focused entirely on roofing skills and knowledge.
  4. Bond & Insurance: You’ll need to secure a contractor’s bond worth $15,000 (yep, that’s required by the state) and liability insurance—because accidents happen, right?
  5. Fingerprinting: Time for a background check! Fingerprinting is mandatory, so schedule yours early.
  6. Fees: Don’t forget to pay the required fees—to become licensed, it literally pays to invest in yourself.

Keep in mind, the CSLB updates requirements periodically. It’s smart to check their site for the latest details.

Wondering How Often You Need to Renew Your C39 License?

Good news—it’s not an every-month kind of thing. Once you’ve got your license, you’ll need to renew it every two years. Mark your calendar, stay on top of your paperwork, and make sure to submit that renewal application before it expires. Why risk losing such an important credential just because you missed the deadline?

What Should You Study for the C39 Exams?

Thinking about the exams? Preparation is key, and the right study materials will make your life so much easier. Here’s what you’ll want to try:

  • C39 Trade Exam: This is your go-to guide for everything roofing, like planning, job site prep, safety protocols, and estimating costs.
  • Law & Business Exam: Covers contracting rules, business practices, and licensing requirements.

You’ll also want to get familiar with the 2022 California Residential Code, which lays out roofing standards and essential requirements. And if you’re aiming for mastery, check out resources like the NRCA Roofing Manuals and the Concrete and Clay Tile Installation Manual for deep dives into specific roofing topics.

But wait—are you worried about the actual test format? Practice tests can be a game-changer. They simulate the exam environment and help you build confidence before the big day. Look into these:

Have you ever taken a mock test before? If not, it’s definitely worth your time. It’s like preparing for a sports game—practice makes perfect.

F.A.Q.

Here are some of our frequently asked questions:

 

Are these the questions that are on the test?
No. No one knows that questions will be on the test and you don’t need to know the answers.  These tests will help you learn the book which is what you need to pass the test.
I pass the practice tests with no problem, now what?
Schedule your test by following the link above and get it on the calendar.  Some of these testing sites are booked months out, so it is best to schedule your test as soon as possible.
Once I pass the protored test, can I do licensed work?
Merely achieving success in these exams does not suffice for acquiring a license. Those seeking licensure must submit a license application to the relevant state or local boards and fulfill the specific conditions set by those authorities. It is recommended to thoroughly examine these prerequisites before taking the exam. The most comprehensive information about these prerequisites can typically be obtained by directly contacting the issuing board.

In many jurisdictions, license holders are obligated to undertake ongoing education on a yearly or biennial basis to ensure license renewal.

I can't pass the practice tests. Please help?!
Keep taking the tests and learning how to navigate the books.  The Table of Contents and Index are your best friends.
How come you don't bundle the books together with tabs like other websites?
There is no need to overpay for books and highlighting suggestions.  No one knows what will be on the test ahead of time so spending hours tabbing and highlighting is irrelevant and time consuming.  To pass the test, all you need to know is how to find the answers and using our practice test will help you.

 

The majority of state licensing exams are designed as OPEN BOOK assessments, indicating that success is not contingent on rote memorization. Instead, the aptitude to swiftly locate answers holds greater significance than committing content to memory. We firmly hold the belief that our Practice Exams serve a dual purpose: not only will they enhance your familiarity with the subject matter at hand, but they will also cultivate your proficiency in promptly and effectively retrieving answers from any reference material.
