IL-ROOF Passing Score 2026: Exactly What You Need to Pass

TL;DR
  • You need a raw score of 70 or higher on the CTS-administered Illinois Roofing exam to pass.
  • The exam has 130 multiple-choice questions in 150 minutes across six domains.
  • Steep-Slope Roofing Systems carries 35 questions, the single largest share of your score.
  • The current CTS exam fee is $248, separate from the $125 IDFPR business-license application.

The Passing Score Number Explained

If you're studying for the Illinois Residential, Commercial and Industrial Roofing Examination (profession 105/test 03), the number that matters most is simple: 70. Continental Testing Services (CTS), the vendor that administers the exam on behalf of the Illinois Department of Financial and Professional Regulation (IDFPR), sets the passing threshold at a score of 70 or higher out of 130 multiple-choice questions.

There's no domain-by-domain minimum published by CTS - your overall raw score across all six content areas is what determines pass or fail. That means a weak showing in one domain can be offset by strength in another, but it also means you can't afford to treat any of the six domains as optional during your prep.

Quick Reference: 130 questions, 150 minutes, passing score of 70 or higher. This applies to the unlimited license route through the full Illinois Residential, Commercial and Industrial Roofing Examination.

Exam Format: 130 Questions, 150 Minutes

The exam is entirely multiple choice - 130 items to be completed in 150 minutes. That works out to a little over a minute per question on average, which is a workable pace if you know the material, but tight if you're second-guessing yourself on definitions or code references.

Because the format is fixed and the passing bar is a flat 70, your prep strategy should focus on accuracy across content you're likely to see repeated multiple times, rather than trying to memorize obscure edge cases.

How the 130 Questions Break Down by Domain

CTS publishes exact item allocations for each of the six content domains. Understanding this breakdown is the single most important thing you can do before you open a study guide, because it tells you exactly where your points are concentrated.

DomainQuestionsShare of Exam
Domain 1: Safety & Employee Protection25~19%
Domain 2: Roofing Preparation & Materials20~15%
Domain 3: Steep-Slope Roofing Systems35~27%
Domain 4: Low-Slope Roofing Systems15~12%
Domain 5: Rules, Regulations & Business Practices20~15%
Domain 6: Non-Residential Roofing Systems15~12%

Steep-Slope Roofing Systems is the largest domain at 35 questions, followed by Safety & Employee Protection at 25. Together those two domains account for roughly 46% of the entire exam. If you're only going to deeply master a handful of topics, these two need to be at the top of the list. For a complete breakdown of what each domain actually tests, read IL-ROOF Exam Domains 2026: Complete Guide to All 6 Content Areas.

Domain 3: Steep-Slope Roofing Systems (35 questions)

This is the heaviest-weighted domain on the exam, covering the installation methods, materials, and detailing that apply to sloped residential and commercial roofing.

  • Shingle, tile, and slate installation sequencing
  • Flashing details at valleys, chimneys, and penetrations
  • Underlayment selection and application in Illinois climate conditions

Domain 1: Safety & Employee Protection (25 questions)

The second-largest domain, focused on fall protection, jobsite hazard awareness, and employee safety practices roofing contractors are expected to enforce.

  • Fall-protection equipment and anchor point requirements
  • Ladder and scaffold safety on steep and low-slope work
  • General OSHA-aligned safety references cited in the CTS study guide

What Scoring 70 Actually Requires

A passing score of 70 on a 130-question exam means you need to answer approximately 91 questions correctly (70% of 130). Because the exam mixes six domains of varying weight, the practical implication is that you can't pass by being excellent in only one or two areas - you need solid, consistent performance across all six, with particular strength in the two heaviest domains: Steep-Slope Roofing Systems and Safety & Employee Protection.

Key Takeaway

Treat the 70-point threshold as a floor, not a target. Aim to over-prepare in Steep-Slope Roofing Systems and Safety & Employee Protection since missed points there are the hardest to make up elsewhere.

The current CTS-linked study guide, dated May 2021, lists the reference materials the exam draws from: NRCA roofing, safety, waterproofing and repair references, roofing estimating guidance, NASCLA business material, and Illinois law and rules. Every one of the six domains maps back to one or more of these source categories, so building your study plan around these references - rather than generic roofing trivia - is the most direct path to a passing score. For a structured walkthrough of how to use these references efficiently, see IL-ROOF Study Guide 2026: How to Pass on Your First Attempt.

Registration, Fees, and Deadlines Tied to Your Score

Passing the exam is only useful if you've registered correctly and understand what happens next. Here's what the mechanics look like:

  • The current CTS exam fee is $248, paid separately from any licensing costs.
  • The IDFPR business-license application carries its own $125 fee, submitted after you pass.
  • CTS administers the exam at Hillside and Springfield testing locations.
  • The November 4, 2026 examination date has an October 7, 2026 registration deadline.
  • You must complete the full application and examination process within three years.

Because the responsible qualifying party is the individual who sits for the exam on behalf of the business, that person must be authorized to supervise installation and participate in day-to-day operations - this isn't a credential you can hold on behalf of a company without real operational involvement. For eligibility specifics, see IL-ROOF Requirements 2026: Eligibility, Prerequisites & How to Qualify, and for a full cost breakdown including bonding and insurance, see IL-ROOF Certification Cost 2026: Complete Pricing Breakdown.

Timing Matters: Missing the October 7, 2026 registration deadline means waiting for the next scheduled date. Check current testing windows before you build your study calendar - see IL-ROOF Exam Dates 2026: Testing Windows, Deadlines & Scheduling for the latest schedule.

Where to Spend Your Study Time

Given the fixed passing score of 70 and the fixed domain weights, your time is best allocated proportionally to each domain's question count, with extra buffer time on the two largest domains. A rough four-week allocation might look like this:

Week 1

Steep-Slope Roofing Systems & Roofing Preparation & Materials

  • Work through NRCA steep-slope installation references
  • Review shingle, tile, and flashing detailing scenarios
Week 2

Safety & Employee Protection

  • Study fall-protection and jobsite hazard material
  • Review NRCA safety references from the CTS study guide
Week 3

Low-Slope & Non-Residential Roofing Systems

  • Review waterproofing and repair references for low-slope systems
  • Study commercial/industrial roofing distinctions
Week 4

Rules, Regulations & Business Practices

  • Study NASCLA business material and Illinois law and rules
  • Take a full-length practice run under the 150-minute time limit

This kind of proportional scheduling works because it mirrors how the exam is actually weighted - not because of any generic study framework. If you want a condensed reference for last-minute review, bookmark IL-ROOF Cheat Sheet 2026: One-Page Review of Must-Know Facts for the final week before test day. You can also build timed practice sessions on our practice test platform to simulate the real 130-question, 150-minute format before you sit for the actual exam.

Test Day Materials and Rules

Test day logistics are straightforward, but overlooking them can cost you time or focus during the exam:

  • Bring two No. 2 pencils.
  • A non-programmable, non-printing solar- or battery-powered calculator is permitted - confirm your calculator meets this standard before test day.
  • Testing occurs at CTS-designated locations in Hillside and Springfield.
  • The 150-minute time limit is fixed; there's no indication of extra time for standard registrants, so pace yourself against the 130-question count from the start.

After You Pass: What Still Has to Happen

Scoring 70 or above is a milestone, not the finish line. Passing the exam alone does not issue the business license. You still need to:

  • Submit the separate IDFPR license application with the $125 fee.
  • Provide supporting entity, insurance, and bonding records.
  • Secure a $25,000 continuous surety bond (the bond face amount, not the premium).
  • Carry at least $250,000 in property-damage coverage and $500,000 in personal-injury/bodily-harm coverage per occurrence, plus applicable employment coverage.

Once licensed, remember that licenses expire December 31 of odd-numbered years, with the next expiration on December 31, 2027. Renewal runs $62.50 per year, or $125 for the standard two-year cycle, contingent on maintaining insurance, bonding, and designated-qualifying-party compliance.

Key Takeaway

Passing your exam with a score of 70+ is the gateway step. Budget time and money for the separate $125 license application, bonding, and insurance before you consider the process complete.

If you're still deciding whether the full unlimited license route or the residential-first path makes more sense for your situation, it's worth reviewing how the credential is structured overall - see IL-ROOF Certification and What Is IL-ROOF Certification? for context, and IL-ROOF Jobs for how licensed contractors put this credential to use in the field. You can also run through timed practice sets on our exam prep platform as you finalize your study plan.

What score do I need to pass the IL-ROOF exam?

You need a raw score of 70 or higher out of 130 multiple-choice questions on the Illinois Residential, Commercial and Industrial Roofing Examination administered by Continental Testing Services.

Is there a minimum score required for each domain?

No. CTS scores the exam as one overall total across all six domains. There's no published requirement to hit a minimum in any single domain - but heavily weighted domains like Steep-Slope Roofing Systems (35 questions) and Safety & Employee Protection (25 questions) have the most influence on your final score.

How many questions can I miss and still pass?

A passing score of 70 on 130 questions means you need roughly 91 correct answers, leaving room for around 39 missed questions spread across the six domains.

Does passing the exam mean I automatically get my roofing license?

No. Passing establishes eligibility, but you still must submit a separate IDFPR license application with a $125 fee, along with entity, insurance, and bonding documentation, and complete the full process within three years of starting.

What happens if I don't pass by my registration deadline?

You'll need to register for the next available CTS testing date. For example, the November 4, 2026 exam requires registration by October 7, 2026 - missing that window means waiting for the subsequent scheduled date.
