What Is AZ-ROOF?

What Is AZ-ROOF, Exactly?

AZ-ROOF is the working name for the Arizona Roofing Contractor Trade Exam, the trade-knowledge test that candidates take to qualify for a roofing contractor license through the Arizona Registrar of Contractors (AZ ROC). PSI, the testing administrator, files this exam under the code CR-42 Roofing (Residential/Commercial). When people search "AZ-ROOF," they are almost always asking about this specific trade exam and how to prepare for it.

It's worth pausing on that identity because the acronym "AZ-ROOF" isn't officially printed anywhere by PSI or the ROC - it's simply the identifier used across this site and similar prep resources to describe the CR-42 exam. If you're comparing notes with other candidates, you may hear the same test called "CR-42," "the roofing trade exam," or "the Arizona roofing license exam." They're all pointing to the same 50-question test.

Who Administers the Exam and Why It Matters

The Arizona Registrar of Contractors sets licensing policy, but the actual exam delivery is handled by PSI, a third-party testing vendor. PSI publishes the official outline, schedules testing appointments, and scores the exam. This distinction matters because when you're troubleshooting scheduling issues, requesting accommodations, or verifying your score report, you're dealing with PSI's processes layered on top of the ROC's licensing requirements.

The outline currently in effect was revised on June 8, 2023. If you find an old study guide, PDF, or forum post referencing a different question breakdown, treat it with caution - it may predate the current version. Always cross-check with PSI's current candidate information bulletin for CR-42 before relying on any secondary source, including ours.

Exam Format: Questions, Time, and Passing Score

The CR-42 trade exam is built around a straightforward format:

• 50 total questions, multiple choice
• 120-minute time limit
• 70% passing score required

That works out to a little under two and a half minutes per question on average - generous for most items, but tight if you get stuck second-guessing calculation-based questions on estimating or fastener spacing. Pacing is a real factor, not just a knowledge issue, which is why understanding question style matters as much as memorizing facts.

The Six Content Domains

PSI's outline breaks the CR-42 exam into six domains, with published item counts of 5, 5, 20, 10, 6, and 4 questions respectively. That distribution tells you plainly where to invest your study hours.

Because Domain 3 alone accounts for 20 of the 50 questions - 40% of the exam - it deserves proportionally more of your study time than any other area. For a full walkthrough of every domain with more subtopic detail, read AZ-ROOF Exam Domains 2026: Complete Guide to All 6 Content Areas.

What You Can (and Can't) Bring Into the Test

The CR-42 exam is partly open book, which surprises candidates expecting a closed-book format. Approved references you may bring into the testing room include:

• The listed OSHA 29 CFR Part 1926 materials covering construction safety
• IBC or IRC editions - 2009, 2012, 2015, or 2018 (check which edition PSI currently accepts before your appointment)

Important nuance: books like Roofing Construction & Estimating and the NRCA manuals referenced in study materials are study-only resources. You can learn from them, but you cannot bring them into the exam room. Don't confuse "recommended reading" with "permitted reference."

Rules on how you can mark up your permitted references are specific:

• Allowed: pre-existing annotations, highlighting, and permanent tabs made before test day
• Prohibited: loose papers, temporary tabs, or writing in your references during the actual test

A silent, nonprinting, nonprogrammable calculator is permitted for the estimating and quantity-calculation questions. Bring your own - don't count on one being provided.

Where the Exam Fits in Arizona Licensing

Passing the CR-42 trade exam is one piece of a larger licensing puzzle administered by the AZ ROC. It's easy to conflate the trade exam with the full licensing process, so here's how the pieces fit:

• Trade exam (CR-42 / AZ-ROOF): Tests roofing craft knowledge across the six domains above.
• Statutes and Rules Examination (SRE): A separate exam covering Arizona contracting law and business rules - not roofing craft content.
• Experience requirement: The qualifying party generally needs four years of trade experience, including at least two within the last ten years, with provisions for training credit, reduction, and documentation waivers in certain cases.
• Timing rule: Required written exams generally must be taken within two years before the license application is submitted.
• Business eligibility: Licensing also involves background checks and maintaining the required bond. Note that the license is issued to the business entity, not personally to the qualifying party who passed the exam.

Cost and Renewal Basics

Once licensed, contractors renew on a recurring cycle. For the standard Specialty Dual license category, the renewal totals $650 per two-year cycle, broken down as a $380 renewal fee plus a $270 recovery-fund assessment. This renewal cost is separate from exam fees and any prep materials you purchase along the way, so budget for both the upfront exam process and the recurring licensing cost.

Who Takes the AZ-ROOF Exam

Candidates sitting for the CR-42 exam are typically individuals designated as the qualifying party for a roofing contracting business - the person whose trade knowledge and experience the business relies on to hold its license. This includes:

• Roofing crew leads and foremen moving into a licensing role for a new or existing company
• Owners of small roofing businesses who need to personally qualify their license
• Experienced installers transitioning from working for a licensed contractor to running their own operation
• Estimators and project managers whose roles require demonstrating trade competency for licensing purposes

Because the license belongs to the business rather than the individual, some qualifying parties take the exam on behalf of a company that hired them specifically to meet this licensing requirement.

Building a Study Plan Around the Outline

Generic study techniques - spaced repetition, active recall, timed practice sessions - all work, but they're only useful once mapped to the CR-42 outline's actual weighting. Since Domain 3 carries 20 of 50 questions, it deserves multiple study sessions while a 4-question domain like Repairs and Reroofing needs just enough attention to avoid careless misses.

Whatever plan you follow, timed practice under real exam conditions matters more than passive review. You can run full-length simulations of the CR-42 format at our practice test platform to get comfortable with the pacing before test day.
