12.1 Illinois Roofing Industry Licensing Act Overview
Quick Answer: The Illinois Roofing Industry Licensing Act (225 ILCS 335) is the state statute that requires roofing contractors to hold an Illinois license administered by the Illinois Department of Financial and Professional Regulation (IDFPR). Its purpose is to protect the public. The Act defines who must be licensed, creates Limited and Unlimited license paths, requires a designated qualifying party, and sets bonding, insurance, and examination rules that appear throughout the CTS Illinois jurisprudence content.
If you plan to run a roofing business in Illinois—or serve as the person who qualifies a company for its license—you need more than installation skill. Domain 5 of the CTS outline (Rules, Regulations, and Business) expects you to know how Illinois law frames the profession. This section builds the foundation: why the Act exists, who enforces it, and who is covered.
Purpose of the Act
The General Assembly enacted 225 ILCS 335 to protect the public. Roofing work affects weather resistance, structural integrity, interior finishes, and occupant safety. Unlicensed or poorly supervised work can leave homeowners and businesses with leaks, mold, fire hazards, and costly remediation. Licensing creates a legal gate: before a person or entity holds itself out as a roofing contractor in Illinois, it must meet statutory and Department requirements and remain accountable to IDFPR.
For exam purposes, treat "protect the public" as the Act's primary purpose statement. Secondary themes—competent practice, financial responsibility, and clear business accountability—all support that consumer-protection goal.
Who Administers the Act?
The Illinois Department of Financial and Professional Regulation (IDFPR) administers the Roofing Industry Licensing Act. In practical terms, IDFPR:
- Issues Limited and Unlimited roofing contractor licenses
- Accepts applications, fees, bonds, and insurance certifications
- Authorizes qualifying-party examinations
- Investigates complaints and disciplines licensees
- Maintains licensing records and forms used in the application process
When study materials refer to "the Department," they mean IDFPR in this context.
Roofing Advisory Board
The Act also contemplates a Roofing Advisory Board. The Board advises IDFPR on matters affecting roofing practice, licensing standards, and related regulatory issues. You do not need to memorize every procedural detail of Board appointments for most exam items, but you should recognize that:
- Licensing is not a pure paperwork exercise—professional input informs Department decisions
- The Board's role is advisory to the Department, not a substitute for IDFPR's licensing authority
- Questions may pair "IDFPR administers" with "Roofing Advisory Board advises" as a paired fact pattern
Who Is a Roofing Contractor?
Under the Act, a roofing contractor is a person or entity engaged in the business of constructing, reconstructing, altering, maintaining, or repairing roofs. The definition is broader than "installing shingles on a house." It reaches commercial and industrial work for Unlimited licensees and includes related waterproofing activities when those activities fall within the Act's scope.
Waterproofing Over Occupiable Space
A frequently tested nuance is waterproofing over occupiable space. When waterproofing is performed above areas people occupy or use, Illinois treats that work as part of the regulated roofing/waterproofing universe covered by licensing expectations. Exam writers use this point to catch candidates who think licensing applies only to steep-slope asphalt shingles. Flat roofs, plaza decks, and membrane systems over occupied floors can still trigger Act coverage when the work is roofing or waterproofing within the statutory meaning.
Keep this comparison in mind:
| Activity | Licensing implication |
|---|---|
| Constructing or repairing a roof covering | Generally regulated roofing work |
| Waterproofing over space occupied or used by people | Within the Act's regulated scope |
| Selling materials only, with others performing the work | Often outside seller-as-contractor rules (see exception below) |
| Acting as the contractor who performs or controls the work | License required |
Sellers Exception
Section 3 of the Act includes an important carve-out: nothing in that licensing-application section applies to a seller of roofing services or roofing materials when the construction, reconstruction, alteration, maintenance, or repair of roofing or waterproofing is performed by a subcontractor or a person other than the seller or the seller's employees.
In plain language:
- A materials supplier or broker who sells and does not perform the work with its own crew is not automatically treated as the licensed roofing contractor under that provision
- The party that actually performs (or whose employees perform) the roofing/waterproofing work is the one that must be properly licensed
- Exam traps often describe a "seller" who also sends its own employees to install—those sellers are not relying on the exception
Why This Matters on the CTS Exam
Illinois jurisprudence is tested on both Limited and Unlimited exams (225 ILCS 335/3.5). Candidates often under-prepare for statute and licensing questions because they focus on flashing details and fastener patterns. Domain 5 rewards precise recall of:
- The Act citation family: 225 ILCS 335
- Public-protection purpose
- IDFPR as administrator
- Advisory Board role
- Contractor definition and waterproofing-over-occupiable-space scope
- Seller exception when work is done by others
Master these building blocks before you move into license types, qualifying parties, bonds, and insurance. Later sections assume this framework.
Study Checklist
- State the Act's purpose in one sentence: protect the public
- Name the administering agency: IDFPR
- Identify the advisory body: Roofing Advisory Board
- Explain when waterproofing is treated as regulated work
- Distinguish a true seller exception from a seller who also installs

Putting the Overview Together
Before you sit for the CTS Illinois exam, be able to narrate the Act in one short paragraph: Illinois licenses roofing contractors under 225 ILCS 335 to protect the public; IDFPR runs the program with advice from the Roofing Advisory Board; the regulated activity includes roof construction and repair plus waterproofing over occupiable space; and sellers who do not perform the work with their own people are treated differently from contractors who actually do the work. That narrative is the backbone for Limited versus Unlimited licensing, qualifying-party duties, and financial-responsibility rules covered next.
