To roof for pay in Illinois you need a state roofing contractor license from IDFPR. You pass a Continental Testing exam (70% to pass), carry general liability and workers’ compensation insurance, post a surety bond ($10,000 Residential or $25,000 Unlimited), and file a $125 application. Most contractors should pursue the Unlimited license, and here is exactly how to do it.

Who Needs an Illinois Roofing License?

Illinois licenses roofing at the state level through the Illinois Department of Financial and Professional Regulation (IDFPR), under the Roofing Industry Licensing Act. If your business contracts to install, repair, or waterproof a roof, residential or commercial, you must hold a valid Illinois roofing contractor license. There is no city-only workaround: the state license is what lets you bid, pull permits, and enforce your contracts.

• New roofers going out on their own for the first time
• Early-stage contractors formalizing a business they have been running informally
• General contractors expanding into roofing so they can self-perform instead of subcontracting
• Out-of-state contractors moving into the Illinois market

Residential vs Unlimited: The Quick Facts

Illinois issues two classes of roofing license. Here is how they compare at a glance.

Which License Should You Get?

For most contractors, the answer is the Unlimited license. Whether you are a brand-new roofer, an early-stage contractor, or a GC adding roofing to your services, the Unlimited license is usually the smarter long-term move, for three reasons.

1. It opens the door to more work, and more profitable work

An Unlimited license lets you take on any roof in Illinois: houses, apartment buildings, commercial buildings, and industrial jobs. That means access to larger contracts and higher-margin projects, and it makes you more valuable both as a general contractor and as a sub other GCs call when a job includes commercial roofing. A Residential license caps you at small residential work before you have even started.

2. You go through licensing once, and get it done right

Licensing takes time and paperwork. Doing it once, at the Unlimited level, means you are not back in the exam room in a year or two trying to upgrade after you turn down a job you could not legally take. Get the full credential the first time and never think about it again.

3. The exam fee is the same either way

Here is the part most people miss: the exam fee is $248 for both. The Unlimited exam is longer (130 questions instead of 80), but it does not cost a dollar more to sit. You are not paying extra for the bigger license, you are simply choosing not to cap your future.

The Requirements

To qualify for an Illinois roofing contractor license, you will generally need to:

• Be at least 18 years old
• Designate a qualifying party, the person who runs day-to-day roofing operations, who passes the state roofing exam
• Carry general liability and workers’ compensation insurance (workers’ comp if you have employees)
• Post a surety bond: $10,000 for Residential or $25,000 for Unlimited
• Submit the IDFPR application with the $125 fee
• Renew on the state’s two-year cycle ($62.50 per year). Illinois does not currently require continuing education for roofing renewal

The Roofing Exam

The exam is administered by Continental Testing Services at sites including Chicago and Springfield. It is closed-book and multiple choice, and you need 70% to pass. The Residential exam is 80 questions in 90 minutes; the Unlimited exam is 130 questions in 150 minutes. It covers Illinois roofing law, safety, roofing materials and methods, and the business and insurance side of running a roofing company.

Step-by-Step: How to Get Licensed

1. Choose your license. For most contractors that is Unlimited, so you can work any roof in Illinois.
2. Prepare for the exam. A focused, in-person prep course is the fastest path to a first-try pass.
3. Register and pass the exam. Sit the Continental Testing exam and clear 70%.
4. Line up insurance and your bond. General liability, workers’ comp if you have employees, and your $10,000 or $25,000 surety bond.
5. File your IDFPR application. Submit the application with the $125 fee and your qualifying party.
6. Get licensed and start bidding. Once issued, you are cleared to contract legally across Illinois.
