What Is a Commercial Roofing Specialist in Illinois?

A commercial roofing specialist in Illinois is a licensed roofing contractor authorized to perform roofing and waterproofing work on all residential, commercial, and industrial properties.

Commercial roofing specialists work on flat and low slope roof systems found on warehouses, schools, hospitals, retail centers, and industrial facilities. The job pays more than residential roofing because of the larger project scale and material complexity.

Which License Do You Need For Commercial Roofing?

According to the Illinois Roofing Industry Licensing Act, you must get an Unlimited Roofing License to become a commercial roofing contractor. Getting an Unlimited License automatically validates you for all types of roofing projects, including:

• Residential Roofing: All residential condos, villas, houses, irrespective of size.
• Commercial Roofing: All commercial ventures including shops and offices.
• Industrial Roofing: All industrial compounds including manufacturing plants etc.

And before you ask, NO, you cannot get a license only for commercial roofing. According to the state of Illinois, you can only get a Limited or Unlimited Roofing License. The former allows you to work on residential project alone, while the latter allows you to work on all projects.

Steps to Becoming a Commercial Roofing Specialist

Getting a roofing license in Illinois follows a clear 7 step process through the IDFPR. Most applicants finish the full path within 3 to 6 months from application to license issuance. The chronological steps are:

1. Apply for the Illinois Unlimited License exam on IDFPR/CTS.
2. Enroll in an exam prep class to lock in your study schedule.
3. Pass the Illinois 105 roofing exam at 70% or higher.
4. Obtain the required surety bond and submit insurance verification.
5. Complete the IDFPR license application and pay the $125 fee.

The Illinois Roofing Institute shortens this timeline by handling the application paperwork, insurance setup, and exam prep in one place. We'll explain each step in detail.

1. Apply for the Unlimited License

Illinois offers two types of roofing licenses, which are:

• Limited License: For residential roofing work on properties 8 or fewer units.
• Unlimited License: For residential, commercial, or industrial roofing projects.

You must choose the Illinois Unlimited Roofing License for commercial roofing work. This is the only license that allows you to work on commercial, industrial, and residential roofing proects.

Now there are two exams that you can attend for an Unlimited roofing license:

• 105 Test-2: For people who want to upgrade from a Limited to an Unlimited license. This exam tests you only on commercial and industrial roofing topics.
• 105 Test-3: For people who do not have any previous active roofing licenses. This exam tests you residential, commercial, and industrial roofing concepts.

Some quick details about the exam:

• Format: Closed book, multiple choice, computer based testing
• Passing Score: 70% on every section
• Commercial Exam Test 2: 80 questions in 90 minutes
• Commercial and Industrial Exam Test 3: 2.5 hours, broader topic coverage
• Exam Fee: $248 per attempt through Continental Testing Services
• Testing Sites: Hillside (Chicago area) and Springfield, Illinois
• Retake Policy: Wait period set by Continental Testing, then pay another $248 fee

You must apply for these exams by filling out the RF-QP form and mailing it to the CTS address. You can also apply online via the CTS website.

2. Prepare For & Pass The Commercial Exam

You can prepare for the roofing exam individually as well, but the exam is hard. You must go through multiple roofing study resources, understand some tricky concepts, and learn about regulations. Multiple students fail the exam on their first attempt.

Each failure cost you $248 because the exam fee is non-refundable. That's why we recommend joining our unlimited roofing class. We are the #1 roofing school in Illinois with a 98% student pass rate on the licensing exam.

We offer English and Spanish roofing classes at the Hoffman Estates campus. Every student gets the full study materials, practice quizzes, and one on one guidance from instructors who are active Illinois roofing contractors.

Our classes give you:

• Full prep coverage for the Illinois 105 roofing exam (Test 1, Test 2, and Test 3)
• Up to date study materials based on the NRCA Roofing Manual and IDFPR references
• OSHA fall protection, ladder, and asbestos rules tested on the licensing exam
• Live instructor led sessions in English and Spanish
• Practice quizzes that mirror the real exam format and timing
• Help with the IDFPR application, RF INS form, and BD URF bond paperwork
• Insurance setup guidance and W 7 ITIN form support
• Ongoing support after the exam through the Beyond the Exam program

3. Obtain Insurance and Bonding Requirements

Insurance and bonding protect the public and serve as financial proof that a roofing contractor can stand behind the work. Plus you cannot get a license without insurance or a surety bond.

Roofing insurance costs more than the actual license fees. A new roofing contractor should budget for insurance premiums every month. Here's what you should expect:

You can streamline the process by:

• Working with an insurance broker who specializes in roofing contractors.
• Ask the broker to file the RF INS form directly with IDFPR.
• Increase liability coverage above $500,000 for larger commercial roofing projects.
• Keep digital copies of every policy and bond document for IDFPR audits.

We explain all of these requirements in detail through our class. We also have partnerships with multiple vendors across Illinois.

4. Complete the IDFPR License Application

You must fill the final license application form (RF) after you get all the necessary documents. This is the form that the IDFPR keeps in its database. Here's what you have to do:

• Download the RF Form form IDFPR.
• Fill it out truthfully and accurately.
• Pay the $125 application fee to the IDFPR.
• Attach all the necessary documents.
• Submit the application via mail.

After that, you have to wait. It can take anywhere between 4 to 8 weeks for the IDFPR to finalize your license. This is also precisely why you must fill out the RF form thoroughly and accurately.

Any missing or incorrect information will cause a rejection. In that case, you'll have to reapply and go through the whole process again.

Beyond the Exam: Launching Your Career

Passing the Illinois 105 roofing exam is the first step. Becoming a true specialist requires additional certifications and training. Fortunately, you can get multiple manufacturer certifications to validate your experience.

Some great roofing certifications that you can get for specialization are:

• NRCA ProCertification
• OSHA 10 & 30 Safety
• Carlisle Syntec Applicator

These certifications help you stand out as a specialized commercial roofer. Other than this, you can network and build connections to boost your credibility. Don't know where to start? Join our roofing class where hundreds of other roofers are waiting to meet you.
