The Illinois roofing exam is a closed-book, multiple-choice test administered by Continental Testing Services. You need 70% to pass. The Residential exam is 80 questions in 90 minutes; the Unlimited exam is 130 questions in 150 minutes. It is based on nationally recognized roofing standards plus Illinois law, and many contractors relying on practical experience fail their first attempt without focused exam preparation.
What Is on the Exam
The roofing exam is broader than the work you do on a roof every day. It pulls from four areas, and the sections that trip people up are usually the ones off the ladder:
- Illinois roofing law and licensing rules. The statute and regulations that govern licensed contractors.
- OSHA & safety. Fall protection and jobsite safety standards.
- Roofing materials and methods. Systems, installation, and best practices based on nationally recognized roofing standards.
- Business and insurance. Contracts, insurance, and the rules of running a roofing company.
Format and Scoring
Both exams are closed-book and multiple choice, and both require a 70% score. The difference is length, which follows the license you are after.

Why People Fail
Failing the roofing exam usually has nothing to do with whether someone can install a roof. It comes down to a few predictable traps:
- Underestimating the law and business sections, which are hard to learn on the job
- Studying from a stack of books without knowing what is actually tested
- Poor time management on a timed exam, especially the longer Unlimited test
- Walking in cold with field experience but no exam-specific prep
How to Study Efficiently
You do not need to read everything. You need to study the right things in the right order:
- Start with the law and business material. This is where most points are lost, so front-load it.
- Use practice questions to find your gaps. Treat each one as a diagnostic, then study your weak areas instead of everything.
- Practice under time. Get comfortable with the pace before exam day, especially for the 130-question Unlimited test.
- Learn from someone who knows the exam. A focused course tells you what to study so you are not guessing.
Exam Day and After You Pass
On exam day, bring your identification, arrive early, and pace yourself against the clock. Once you pass, you move on to insurance, your surety bond, and the IDFPR application to finish getting licensed. From there you are cleared to bid work legally across Illinois.
Why In-Person Beats Books and Online
You can buy a book or a cheap online course, but the exam is exactly where that approach costs people the most, because a failed attempt means paying the $248 again and losing weeks. In-person prep is faster because you can ask questions, get the material explained by someone who knows the test, and stay accountable. We have taught this way in Chicago since 2010, as the first Illinois company built around the roofing exam.

How many questions are on the Illinois roofing exam?
The Residential exam has 80 questions in 90 minutes. The Unlimited exam has 130 questions in 150 minutes. Both are closed-book and multiple choice.
What is the passing score?
70% on either exam.
How hard is the Illinois roofing exam?
Hard enough that many contractors fail without preparation. The toughest parts are the law and business sections, not the hands-on roofing. Focused prep is what gets most people through on the first try.
Can I retake the exam if I fail?
Yes, but you pay the $248 fee again each time you sit it, plus you lose the weeks you could have been working licensed. That is why first-try prep is worth it.
How long should I study?
It varies by background, but efficient, exam-focused prep beats months of unfocused reading. Our in-person course is built to get you ready quickly by concentrating on what is actually tested.
The Bottom Line
The Illinois roofing exam is passable, but it is not a formality. Know the format, respect the law and business sections, study what is actually tested, and practice under time. Do that and you pass the first time, which is also the cheapest way through. In-person prep is the fastest route, and it is what we have done in Chicago since 2010.
