In this guide, we’ll explore the difficulty level of the Illinois roofing exam, how it compares to Florida’s requirements, what study resources are available, and how you can transition smoothly between states while maintaining compliance with local regulations in both Illinois and Florida.

Understanding the Illinois Roofing License Requirements

Before diving into the exam difficulty, it’s essential to understand what Illinois requires to legally perform roofing work. The Illinois Department of Financial and Professional Regulation (IDFPR) oversees all roofing contractor licensing in the state.

Illinois issues two primary roofing licenses:

  • Limited Roofing License: Allows roofing work on residential properties with eight or fewer units.
  • Unlimited Roofing License: Permits roofing work on all property types, including commercial and industrial buildings.

To obtain either license, contractors must:

  1. Be at least 18 years old
  2. Have liability and property damage insurance
  3. Obtain a surety bond
  4. Pass the state roofing license exam

These licensing standards ensure that only qualified professionals handle roofing installations and repairs, minimizing risks to consumers and property. See roofing contractors for more.

How Difficult Is the Illinois Roofing License Exam?

Now let’s get to the crux of the matter: how hard is the Illinois roofing license exam? Here’s what you need to know.

1. Exam Format

The Illinois roofing exam is a closed-book, multiple-choice test administered by Continental Testing Services (CTS) on behalf of IDFPR. You’ll need to choose either the limited or unlimited exam based on the type of license you’re pursuing.

  • Limited License Exam: Covers residential roofing practices.
  • Unlimited License Exam: Includes both residential and commercial/industrial roofing codes and standards.

Each test typically spans 100–125 questions with a time limit of 3–4 hours.

2. Topics Covered

The exam content is aligned with the International Building Code (IBC) and OSHA regulations, including:

  • Roofing materials and installation practices
  • Flashing and sealing procedures
  • Roofing safety and fall protection
  • Illinois-specific administrative rules
  • Business and law essentials

Contractors from West Palm Beach used to Florida codes will notice that Illinois’ roofing standards have their own regional nuances—especially regarding snow load, ice dam prevention, and insulation.

3. Passing Score

You’ll need at least a 70% score to pass. While that sounds achievable, many candidates find it deceptively tricky due to technical jargon, scenario-based questions, and legal specifics.

Is It Harder Than Florida’s Roofing License Exam?

Florida, known for strict contractor licensing through the Florida Department of Business and Professional Regulation (DBPR), also requires roofers to pass a challenging trade and business exam. However, some differences exist:

CriteriaIllinois ExamFlorida Exam
TypeSingle roofing examTwo-part: trade + business
ScopeRoofing onlyBroader in administrative topics
Region-SpecificMidwestern codes (e.g., snow loads)Coastal/hurricane-specific codes
FormatClosed-bookOpen-book

In some respects, Florida’s open-book approach can make it easier to find answers, even if the material is more expansive. Illinois, with its closed-book structure, demands memorization and applied understanding.

💡 Verdict: The Illinois roofing license exam is moderately difficult. If you’re already licensed in West Palm Beach, Florida, and familiar with roofing code intricacies, you’re likely well-prepared for the exam—but you’ll need to adapt to Illinois’ climate-specific requirements and test format.

West Palm Beach Contractors: Why Consider Illinois?

For contractors based in West Palm Beach, expanding to Illinois could be a smart business move. While Florida’s market is robust, seasonal shifts and hurricane damage create volatility. Illinois offers a complementary rhythm—winter repairs, spring builds, and year-round commercial roofing work.

Major cities like Chicago, Rockford, and Springfield have dense urban infrastructure and a high demand for skilled roofing professionals. Pair that with ongoing roofing industry growth and you’ll find a fertile landscape for expansion.

Bonus: Holding licenses in multiple states builds your credibility, opens up cross-state contracts, and strengthens your reputation as a licensed roofing authority. See roofing contractors for more.

Staying Compliant in Both States

Operating across state lines requires attention to detail. In addition to passing Illinois’ roofing exam, make sure you:

  • Maintain insurance and bonding standards for both states.
  • Register your business as a foreign entity in Illinois.
  • File necessary paperwork with local municipalities (Chicago and suburbs have separate permitting systems).
  • Stay updated on code changes, including Florida’s ongoing updates to hurricane-resistant materials and Illinois’ adoption of energy-efficient roofing systems.

Final Take: Should You Be Worried?

🙄 Short answer? No. Long answer? Not if you prepare smartly.

The Illinois roofing license exam is not easy—but it’s not insurmountable either. For a West Palm Beach contractor with Florida licensing experience, passing it is well within reach. Think of it as a professional milestone that not only validates your skills but also expands your market influence.

With strategic study, proper exam prep, and a little Midwest mindset adjustment, you’ll be licensed in Illinois in no time.
