Choosing which state roofing license you should get requires careful consideration of a list of factors. This guide gives you a detailed comparison of a Limited vs Unlimited Illinois Roofing License. By the end of this guide, you should be able to choose between the two licenses.

According to the state of Illinois law, you will need either of these licenses for your potential roofing work. Both of these are obtainable through the Illinois 105 Roofing Exam. We'll look at the details of these two licenses to remove confusion about your choices. 

1. Purpose of Unlimited vs Limited Roofing License

The Limited Roofing License is ideal for contractors focused on residential roofing projects that are 8 units or fewer. Simply put, the Limited Roofing contractor license is for contractors aiming to work on smaller-scale residential roofing projects. For example:

  • Single-family homes
  • Duplexes
  • Townhouses 
  • Small apartment buildings 
  • Condominiums 
  • Row houses
  • Accessory dwelling units (ADUs)

The unlimited roofing contractor license is for residential, commercial, and industrial roofing work. According to the Illinois Roofing Industry Licensing Act, an Unlimited License holder can work on a property of any size. Some of the properties that you can perform roofing on are: 

  • Large apartment complexes
  • Office buildings 
  • Retail stores
  • Restaurants
  • Schools and universities
  • Hospitals and healthcare
  • Government buildings 
  • Stadiums and arenas

The IDFPR and its subsidiary, the Registrar of Contractors, manage these licenses. According to Illinois Law, even if you're a General Contractor, you'll need a valid roofing license to take on projects. 

Which Illinois roofing license should you get?

You should get a Limited Roofing license if you plan to work on residential roofing projects. However, you should get an unlimited roofing license if you’re open to a broader scope of work and plan to undertake larger projects, such as office buildings, hospitals, schools, and others.

Conclusively, an unlimited license opens up more options for you. It’s better to get an unlimited roofing license in Illinois if you want to work on commercial, industrial, & and residential projects.

2. Price of Limited vs Unlimited Roofing License

According to the Illinois Department of Financial and Professional Regulation (IDFPR), the price of a Limited and Unlimited Roofing License Application is $125. Both exams have a $248 examination fee, which brings the total to around $400. 

One notable difference in cost is the acquisition of surety bonds. Unlimited Licensees must acquire a surety bond of $25000, while Limited Licensees only need a surety bond of $10000. Another difference is that industrial properties and projects require more extensive insurance than small-scale residential projects.

Which Illinois roofing license is cheaper?

The Limited Roofing License in Illinois is cheaper because it has lower surety requirements. The official cost for application and examination is similar for both licenses. Here’s a cost breakdown of both licenses:

Cost Points Limited License Unlimited License
Application Fee $125 $125
Examination Fee $248 $248
Surety Bonds $10000 $25000
Insurance Requirements General Liability and Workers' Compensation General Liability, Workers' Compensation, and/or Auto

The surety bonds and insurance policies are a basic roofing license requirement. You cannot undertake any roofing project without these insurances. However, the good news is you can get most insurance policies through a local lender or agency. 

Unlimited Licenses and commercial projects require extensive insurance policies because of the scope of the work. Residential projects are usually isolated and have lower costs. You can find more information about the insurance policies from licensed roofing contractors on different forums like Reddit and Roofing Talk. 

3. Exam Types for Unlimited and Limited Licenses

Both Limited and Unlimited licenses require roofing exams, but the Unlimited License has two possible exam paths. You can only get the Limited License through the Illinois 105 Roofing Exam Code 1. However, you can obtain the Unlimited License through the 105 Roofing Exam Code 2 and 3. 

There is one caveat to Exam Code 2, because it's an upgrade exam. You can only attempt exam code 2 when you've had the Limited License for at least one year. Furthermore, the fees for all exams and applications are similar, so you pay twice the amount if you give Exam 1 and 2 to get the Unlimited License. 

Here are the three options you can take:

Scenarios Requires Exam Code 1 Requires Exam Code 2 Requires Exam Code 3 Overall Costs
Stay a Residential Roofer Yes No No Standard Costs
Upgrade From Residential License Yes Yes No Double Costs
Get an Unlimited License From Get-Go No No Yes Standard Costs

Note: To attempt the upgrade exam, a roofing contractor must pass the residential exam first. 

4. Preparation Time for Unlimited vs Limited Roofing License

Limited License exams are centred around residential projects, which means you have to study fewer topics. It reduces the preparation time significantly. Unlimited Licenses have topics around multiple safety protocols, laws, and roofing concepts.

You can get all the study materials from the National Roofing Contractors Association (NRCA) website. On average, you'll need 45 to 60 days to prepare for the Limited License exam. The Unlimited License exam requires more than 60 days for complete preparation. 

You must follow the right prep methods to pass these roofing exams. Go through the study materials, attempt practice exams, and acquire hands-on experience. 

Which roofing license needs more prep time?

The Unlimited Roofing License needs more prep time due to its larger scope of work. It requires a higher degree of roofing knowledge and local requirements. The Limited License exams only include topics about residential properties and safety laws.

Here's a breakdown of the exam and included topics:

Exam Structure Limited License (Residential Roofing) Upgrade Exam (Commercial, Industrial) Unlimited License (Residential, Commercial, Industrial)
Exam Test Code 1 2 3
Safety & Employee Protection Questions 25 15 25
Roofing Preparation & Materials 12 10 30
Steep-Slope Roofing Systems Questions 20 15 25
Low-Slope Roofing Systems Questions 8 10 15

Rules,  Regulations, and Business Practices Questions

15 15 20
Non-Residential Roofing Systems Questions None 15 15
Total Questions 80 80 130

The study requirements for roofing exams have a clear difference. The Unlimited Roofing Exam has more topics and requires more study. The Limited license and the upgrade exams are much easier because they have a limited number of questions.

4. Difficulty of Limited vs Unlimited Roofing License

The Limited and Unlimited roofing licenses are hard to obtain because of their unique scopes of work. While the Limited Roofing license focuses primarily on residential projects, the unlimited one covers a broader range of projects. Naturally, the Unlimited License is more difficult to obtain.

In the Unlimited License Exam (Code 3), roofing contractors must answer 130 questions in 150 minutes. While the time per question is still the same, the overwhelming number of questions carries a mental burden. The Limited License is much easier to obtain because of its limited study and easy exam format.
