Understand the Illinois Unlimited Roofing License. Become a licensed residential, commercial, and industrial roofing professional.
The Unlimited Roofing License allows you to work on all commercial, industrial, and residential roofing projects in Illinois. The IDFPR issues this license when you pass its exam and fulfill the requirements. Working on commercial projects without an Unlimited License is a criminal offense in Illinois.
This license is crucial for both new roofers and business owners. We explain its importance, costs, and requirements in detail in this guide.
An unlimited roofing license is available to contractors whose roofing business is unlimited in nature (see what we did there!). This unlimited license allows the licensed roofing contractor to work on commercial, industrial, and residential properties of any size.
An unlimited license indicates that the roofing professional has the experience and the financial backing to handle complex roofing systems on a massive scale. This is the roofing contractor license you must obtain if you want to work on every type of roof.
The first requirement for a roofing license is designating a qualifying party. The qualifying party is the individual responsible for the day-to-day activities and supervision of roofing installation and roofing practices.
According to the Financial and Professional Regulation guidelines, this person must pass the exam to prove their technical roofing knowledge. The qualifying party serves as the anchor for the state license, ensuring the company remains compliant with Illinois state law.
Here are some key requirements for obtaining the Unlimited roofing license:
Obtaining an Illinois roofing contractor license involves several fixed and variable costs. Beyond the initial application fee, there are high overhead costs that must be managed to keep the roofing business profitable.
The primary state fees remain consistent for both limited and unlimited roofing license applicants. These fees are paid to the Illinois Department of Financial and Professional Regulation and the testing agency.
While the bond amount is fixed ($10,000 for limited and $25,000 for unlimited), the cost you pay is a premium based on your credit score and business history. This is a mandatory roofing license requirement under the Illinois Roofing Industry Licensing Act.
This is often the most significant variable cost. Licensed roofing contractors must carry robust coverage to protect against the high-risk nature of roofing projects.
Roofing insurance costs are higher than the actual cost of a roofing license.
You must pass the Illinois 105 roofing exam code-3 to get an Unlimited license. The roofing exam is administered by state roofing vendors. To obtain a license, the qualifying party must achieve a score of 70% or higher.
The Illinois roofing exam is known for being rigorous, covering roofing and waterproofing, safety (OSHA), and general roofing practices. The exam ensures that the roofing professional is well-versed in both residential and commercial roofing systems.
4 out of 5 first-time candidates fail the Unlimited roofing license exam. Passing the exam requires a deep understanding of the necessary roofing study resources. You must understand core topics like commercial and residential roofing systems, roofing terminologies, and standard regulations.
Many successful candidates use exam prep courses to familiarize themselves with the National Roofing Contractors Association (NRCA) standards. Join our exam prep course to guarantee your success in this exam and in your career.
The process to obtain a roofing license is structured to ensure all legal and safety boxes are checked. Here is the standard path to get your license:
Once you get your license, you must display your license number on all commercial vehicles used for the business and on all contracts. Licensed roofing entities must also stay compliant with the NRCA standards and local building requirements. Failure to maintain a licensed roofing contractor status can lead to fines of up to $1,500 per violation under Illinois state law.
Compliance also extends to the safe handling of roofing materials and adherence to OSHA safety protocols. A licensed roofing professional is expected to maintain high standards for both residential roofing and work on commercial projects. If your roofing business expands, you may need a limited or unlimited license upgrade to reflect the nature of your new roofing projects.
If the qualifying party does not pass the exam, they must reapply and pay the examination fee again. There is no limit on how many times you can take the exam, but the costs can add up quickly, which is why intensive exam prep is highly recommended for any roofer looking to obtain a license on their first try.
For more information on the Illinois roofing industry licensing act or to begin your license application, contact the Department of Financial and Professional Regulation. Whether you are performing general roofing or specialized roofing and waterproofing, being a licensed roofing contractor is the only way to operate a legitimate roofing business in the state of Illinois.
The initial cost for the application and exam is $373. However, when factoring in surety bonds, insurance, and exam prep courses, most contractors should budget between $1,500 and $3,000 to get their license and business fully operational and legally compliant with state roofing regulations.
No. The Illinois Roofing Industry Licensing Act mandates that anyone offering roofing services must be state-licensed roofing professional. Unlicensed roofing work is a criminal offense and can lead to significant legal penalties, including stop-work orders and heavy fines from the registrar of contractors or local building departments.
A limited roofing license is restricted to contractors whose roofing business is limited to residential roofing projects consisting of 8 units or fewer. An unlimited roofing license is required for any work in Illinois that involves industrial properties, large residential complexes, or commercial roofing systems.
A roofing contractor's license in Illinois typically expires every two years in odd-numbered years. You must submit an application for renewal and pay the renewal fee to maintain active status. If your business is unlimited in nature, you must also prove that your bond and insurance are still active during the renewal process.
An Unlimited roofing license is a necessary document for contractors who want to work on any type of roof. You can get this license by passing the 105-3 or 105-2 roofing exam (if you've held the Limited License for 1 year).
Please remember, the Unlimited roofing license exam is much harder than the limited license exam. You will need a deep understanding of residential, commercial, and industrial roofing concepts. Join our exam prep course to ace the exam and get your license.
