OSHA safety standards make up roughly 20 to 30% of the Illinois roofing exam, and fall protection alone can account for 5 to 10 questions. Roofing is the most hazardous construction trade, so the licensing exam tests OSHA hard. Know the 29 CFR sections cold and you take a big bite out of the test.
We'll walk you through every OSHA section tested on the Illinois roofing contractor licensing exam. You'll learn which standards to study, the numbers to memorize, and the 70% passing score you need to hit.
OSHA safety standards are tested heavily on the Illinois roofing exam because roofing stays the most hazardous construction trade. The Occupational Safety and Health Administration (OSHA) sets the federal rules every roofing contractor must follow on the job site.
Fall protection violations alone hit 5,914 citations in fiscal year 2025, topping OSHA's preliminary top 10 list. OSHA's Dallas Regional Administrator Eric Harbin confirmed at the 2025 National Safety Council Congress that roofing, framing, and siding contractors drove most of those fall protection citations.
That real world data is exactly why OSHA shows up so often on the IL roofing contractor exam. The topics you see most include:
Fall protection is the single most tested OSHA topic on the Illinois roofing exam. Subpart M covers Sections 1926.500 through 1926.503 and governs every fall hazard above 6 feet.
Section 1926.501(b)(10) is the rule cited most often on practice exams. It requires fall protection for any worker on a low slope roof with unprotected edges, triggered at 6 feet or more above lower levels.
| OSHA Section | What It Covers | Key Fact to Memorize |
|---|---|---|
| 1926.500 | Scope and definitions for fall protection | Defines low slope as 4:12 or less in pitch |
| 1926.501(b)(1) | Unprotected sides and edges | Fall protection required at 6 feet or more |
| 1926.501(b)(10) | Roofing work on low slope roofs | Warning line, guardrails, or PFAS required above 6 feet |
| 1926.501(b)(11) | Steep roofs | Guardrails with toeboards, safety nets, or PFAS required |
| 1926.502 | Fall protection systems criteria | Anchor points must support 5,000 pounds per worker |
| 1926.503 | Training requirements | Employer must train every exposed worker |
A personal fall arrest system (PFAS) is the harness, lanyard, and anchor setup that stops a worker mid fall. These are the quick memorization points for the fall protection section:
Ladder safety is the third most cited OSHA standard, with 2,405 violations in 2025. Roofers face direct ladder questions on the Illinois exam because nearly every roof access starts with one.
The standard covers portable ladders, fixed ladders, and job made ladders. Memorize the rules on extension, slope, and side rail extension before exam day.
Scaffolding safety is the seventh most cited OSHA standard, with 1,905 violations in 2025. Commercial roofers see scaffolding questions on the Unlimited license exam.
The standard requires every scaffold to support its own weight plus four times the maximum intended load. A competent person must inspect every scaffold before each shift.
Asbestos handling appears on the Illinois roofing exam for any contractor reroofing older buildings. The standard sorts asbestos work into four classes based on the type and risk of exposure.
Removing asbestos containing roofing shingles falls under Class II asbestos work. Asbestos containing material (ACM) is any material with more than 1% asbestos by weight.
Hazard communication is the second most cited OSHA standard, with 2,546 violations in 2025. OSHA flagged roofers as top violators of HazCom in the 2025 data.
The standard requires every employer to keep Safety Data Sheets (SDS) for all hazardous chemicals on the job site. An SDS is a document that lists the hazards, handling, and emergency steps for a chemical.
Respiratory protection is the fifth most cited OSHA standard, with 1,953 violations in 2025. Roofers face dust, fumes, and chemical exposure on most job sites.
The standard requires a written respiratory protection program whenever respirators are used. Workers must be fit tested before they are assigned a respirator.
Personal protective equipment (PPE) and training requirements show up across every section of the Illinois roofing exam. Fall protection training under 29 CFR 1926.503 alone hit 1,907 violations in 2025.
Employers must provide PPE at no cost to the worker. Training has to be documented and updated whenever a new hazard appears on the job site.
Practice questions help you get used to the format and timing of the Illinois roofing exam. You'll want each multiple choice question to take less than 55 seconds, so a timed practice test builds the speed you need.
The questions below match the format of the real exam. Use them as a quick quiz to test recall on the most heavily tested 29 CFR sections, then drill the gaps in our exam prep guide.
| Sample Question | Correct Answer |
|---|---|
| Under 29 CFR 1926 Subpart M, at what height must fall protection be provided for roofing on low slope roofs? | 6 feet (1.8 m) |
| Anchor points for a personal fall arrest system must support how many pounds per worker? | 5,000 pounds |
| A portable ladder used for roof access must extend how far above the upper landing surface? | At least 3 feet |
| What is the minimum slope ratio for a portable ladder used for roof access? | 1 in 4 (1 foot out for every 4 feet up) |
| What is the minimum training duration for Class II asbestos work involving roofing materials? | 8 hours, with hands on practice |
| What is the asbestos PEL over an 8 hour time weighted average? | 0.1 fibers per cubic centimeter |
| How often must respirator fit testing be performed for assigned workers? | Before initial use and at least annually |
Every Illinois roofing exam question is supported by a published reference cited on the Continental Testing study guide. The IDFPR and the National Roofing Contractors Association (NRCA) supply the core materials.
Study only the references cited on the official Continental Testing Roofer Study Guide, which we break down in our roofing exam study resource guide. The main references include:
If you want a deeper read on the law side, our breakdown of the Illinois Roofing Industry Licensing Act covers the rules, lien laws, and business practices the exam expects you to know.
Passing the Illinois roofing exam takes structured study, not last minute cramming. Candidates who follow a 4 to 8 week study plan post the highest pass rates.
Spend the first half of your study time on OSHA and the Illinois Roofing Industry Licensing Act. Use the second half on roof systems, measurement and estimating, and law and project management.
If you'd rather not piece a plan together yourself, that's what we do. Our roofing exam classes in Illinois packs these study sessions into a few focused days and runs you through timed practice tests before exam day.
The passing score on the Illinois roofing exam is 70%, set by Continental Testing Services. Both the Limited and Unlimited license exams use the same threshold. On the 80 question Limited exam, that means answering at least 56 questions correctly.
OSHA related questions make up roughly 20 to 30% of the Illinois roofing exam. Fall protection alone often accounts for 5 to 10 questions. The Unlimited exam tests more commercial OSHA topics like scaffolding and asbestos abatement.
29 CFR 1926 Subpart M (Fall Protection) is the most tested OSHA section on the Illinois roofing exam. Section 1926.501(b)(10) on low slope roof work shows up on every practice exam. Memorize the 6 foot threshold, the 5,000 pound anchor rating, and the warning line distances.
The Illinois 105 roofing licensing exam is a closed book, computer based, multiple choice test through Continental Testing Services. The Limited license exam has 80 questions in 90 minutes. The Unlimited license exam runs 2.5 hours with 130 questions covering commercial topics.
Illinois roofing exams are offered at Continental Testing Services locations in Hillside (the Chicago area) and Springfield. The fee is $248 per exam attempt. Registration deadlines run about four weeks before each scheduled test date.
Yes, a candidate who fails the Illinois roofing exam can retake it after the waiting period set by Continental Testing Services. Most candidates schedule the retake 30 to 60 days later to allow for focused study. Each retake requires a separate $248 exam fee.
Most candidates need 4 to 8 weeks of structured study to pass the Illinois roofing exam. Roofers with prior OSHA 10 or OSHA 30 training often need less. Plan for 6 to 8 hours of study a week, with extra focus on Subpart M and the Illinois Roofing Industry Licensing Act.
OSHA 10 and OSHA 30 training are not formal substitutes for the Illinois roofing exam, but the content overlaps heavily. A roofer with current OSHA 30 training will recognize most fall protection, ladder, and scaffolding questions. The IDFPR still requires the state exam for every Illinois roofing contractor license.
OSHA sections account for a major share of every Illinois roofing exam, with fall protection under 29 CFR 1926 Subpart M leading the way. Roofing contractors who memorize the 6 foot threshold, the 5,000 pound anchor rule, and the 8 hour asbestos training requirement pass at a much higher rate.
