- CR-42 (AZ-ROOF) has 50 questions, a 120-minute limit, and a 70% passing score administered by PSI.
- Roofing systems - including BUR and waterproofing - is the largest tested area, with 20 of the outline's items.
- The exam is partly open book: only OSHA 29 CFR Part 1926 materials and one IBC/IRC edition (2009, 2012, 2015, or 2018) are permitted in the room.
- Training must also account for the separate Statutes and Rules Examination (SRE), a distinct licensing requirement.
What "AZ-ROOF Training" Actually Prepares You For
When people search for AZ-ROOF training, they're really asking how to prepare for the Arizona Registrar of Contractors' CR-42 Roofing (Residential/Commercial) trade exam, administered through PSI. "AZ-ROOF" is simply the site identifier PSI uses for this exam - the credential behind it is the CR-42 license classification that lets a qualified individual serve as the qualifying party on a roofing contractor's business license in Arizona.
That distinction matters for how you train. This isn't a certificate you earn for yourself in the abstract; it's a licensing exam tied to a specific business structure, a bond requirement, and background checks. Training that only covers roofing trivia without connecting it to how PSI actually writes and scores questions will leave gaps. If you haven't already mapped out the full scope of the credential, the overview of what AZ-ROOF certification involves is a useful starting point before you build a study plan.
How the CR-42 Exam Is Structured
Effective training starts with understanding the exact shape of the test, not generic "contractor exam" assumptions. The CR-42 trade exam consists of:
- 50 total questions
- 120-minute time limit
- 70% passing score
PSI's published outline breaks those 50 questions into six sections with item counts of 5, 5, 20, 10, 6, and 4. The 20-item section covers roofing systems, including built-up roofing (BUR) and waterproofing - by far the heaviest concentration on the exam. Any training plan that spends equal time on every domain is mismatched to how the test is actually weighted. For a full breakdown of how those counts map to each content area, see the AZ-ROOF Exam Domains Guide.
The current outline was revised by PSI on June 8, 2023. If your training materials, flashcards, or old study guides predate that revision, cross-check them against the current candidate information bulletin before relying on them.
Key Takeaway
Because roofing systems (including BUR and waterproofing) accounts for 20 of 50 questions, dedicate roughly two out of every five hours of training time to that single domain.
Training By Domain: What Each Section Demands
Generic trade-exam prep treats all content equally. AZ-ROOF training shouldn't. Below is what candidates need to actually master in each of the six domains, weighted by their approximate share of the 50-question exam.
Domain 1: Estimating and Plan Reading
Covers reading roofing plans and specifications, calculating material quantities, and translating architectural details into estimates.
- Squaring measurements, waste factors, and material takeoffs from plan sets
Domain 2: Surface Preparation and Planning
Focuses on evaluating existing decking and substrates, moisture conditions, and pre-installation planning decisions.
- Deck inspection criteria and preparation sequencing before any roofing system goes down
Domain 3: Steep and Low Slope Roofing, Including BUR and Waterproofing
The largest section on the exam. Candidates must know installation methods across shingles, tile, single-ply membranes, built-up roofing, and waterproofing details.
- Slope-specific installation requirements and transitions between steep-slope and low-slope systems
Domain 4: Roofing Components
Tests knowledge of flashing, underlayment, fasteners, ventilation, and drainage components that support the primary roofing system.
- Flashing detail placement at penetrations, valleys, and terminations
Domain 5: Safety
Applies OSHA fall protection and jobsite safety standards to roofing-specific scenarios - one of the few areas where an approved reference is permitted during the exam.
- Fall protection requirements under 29 CFR Part 1926 as applied to roof work
Domain 6: Repairs and Reroofing
Covers diagnosing failures, tear-off procedures, and reroofing over existing systems in compliance with code requirements.
- Determining when reroofing over existing layers is code-compliant versus requiring full tear-off
For a section-by-section study breakdown with more detail on each domain's likely question style, the AZ-ROOF Study Guide 2026 walks through preparation strategies aligned to this exact outline.
Open-Book Rules and Approved References
One of the most misunderstood parts of AZ-ROOF training is the open-book policy - and getting it wrong can cost you materials access on exam day. The CR-42 exam is partly open book, meaning only specific references are allowed into the testing room:
- The listed OSHA 29 CFR Part 1926 materials
- One edition of the IBC or IRC - 2009, 2012, 2015, or 2018
Popular study resources like Roofing Construction & Estimating and the listed NRCA manuals are valuable for learning the material, but they are study-only references - you cannot bring them into the exam. Training plans that don't distinguish between "learn from this" and "bring this to the test" set candidates up for a stressful surprise at check-in.
Because these rules are specific to this exam and easy to get wrong, build a checklist into your training routine well before test day rather than sorting it out the morning of your appointment.
A Realistic Training Timeline
Standard study techniques - spaced repetition, timed practice blocks, review cycles - only help if they're pointed at the right material in the right order. Below is a training sequence built around the CR-42 outline's actual weighting, not a generic template.
Foundations: Estimating, Plan Reading, and Surface Prep
- Practice takeoffs and waste-factor calculations from sample plan sets
- Review deck inspection standards covered in Domain 2
Deep Dive: Roofing Systems, BUR, and Waterproofing
- Spend the most hours here since this domain carries 20 of 50 questions
- Study steep-slope and low-slope installation methods side by side to catch overlap questions
Components, Safety, and OSHA References
- Practice locating fall-protection provisions quickly within your approved OSHA reference
- Review flashing and drainage component scenarios from Domain 4
Repairs, Reroofing, and Full Timed Simulation
- Study tear-off versus reroofing-over-existing code scenarios
- Run a full 50-question, 120-minute practice session under real exam conditions
If you're unsure whether your current pace is adequate given the exam's difficulty, the AZ-ROOF Difficulty Guide breaks down what makes certain domains harder to master than others.
Training Fits Into a Bigger Licensing Path
Passing the CR-42 trade exam is one requirement among several, and training plans that ignore the rest of the licensing path often leave candidates scrambling later. Arizona's statutory baseline requires the qualifying party to have four years of trade experience, including at least two within the last ten years, with certain authorized provisions for training credit, experience reduction, and documentation waivers.
You'll also need to pass the Statutes and Rules Examination (SRE), which is a separate licensing component from the CR-42 trade exam - training for one does not substitute for the other. Required written examinations generally must be taken within two years before application, so timing your CR-42 prep against your overall license application timeline matters.
Beyond the exams themselves, licensing involves business eligibility review, applicable background checks, and maintaining the required bond. It's worth remembering that the resulting license belongs to the business, not the individual qualifying party - a detail that affects how contractors structure their companies around who holds the qualifying role. For the full list of experience and documentation requirements, see the AZ-ROOF Requirements guide, and for a clear explanation of the 70% threshold itself, review the AZ-ROOF Passing Score breakdown.
Key Takeaway
Don't train for CR-42 in isolation - confirm your SRE timing, experience documentation, and bond requirements are moving in parallel, since all of these feed into a single license application.
What Happens After You Pass: Renewal Costs
Training doesn't end at your passing score - license maintenance is an ongoing cost candidates should plan for from the start. The standard Specialty Dual renewal totals $650 per two-year cycle, broken down as follows:
| Renewal Component | Amount |
|---|---|
| Renewal fee | $380 |
| Recovery-fund assessment | $270 |
| Total per two-year cycle | $650 |

Choosing Training Resources That Match the Real Exam
Not all AZ-ROOF training resources are created equal, and given that "AZ-ROOF" is shared by other unrelated credentials in search results, it's worth double-checking that any material you use actually references the PSI-administered CR-42 Roofing exam under the Arizona Registrar of Contractors - not a similarly named certification from another field.
Good training resources for this exam should:
- Reflect the June 8, 2023 outline revision, not an older version
- Mirror the actual six-domain weighting (5, 5, 20, 10, 6, 4) rather than treating every topic equally
- Distinguish clearly between study-only references (like NRCA manuals) and exam-permitted references (OSHA materials and one IBC/IRC edition)
- Include timed, 50-question practice simulations that mimic the 120-minute format
Running full-length timed simulations on the AZ-ROOF practice test platform is one of the most direct ways to confirm your pacing across all six domains before exam day. If you want a fast-reference companion for last-minute review, the AZ-ROOF Cheat Sheet condenses the highest-yield facts into a single page, and you can check upcoming testing windows through the AZ-ROOF Exam Dates guide so your training schedule lines up with an actual appointment.
Whichever resources you choose, treat the main practice test site as your benchmark for readiness - if your simulated scores are consistently clearing 70% with room to spare across all six domains, your training has done its job.
FAQ
No. The CR-42 trade exam and the Statutes and Rules Examination (SRE) are separate licensing components with different content. Training for one does not prepare you for the other.
Domain 3, Steep and Low Slope Roofing including BUR and Waterproofing, carries 20 of the exam's 50 questions and should receive the largest share of study time.
No. NRCA manuals and Roofing Construction & Estimating are study-only references. Only the listed OSHA 29 CFR Part 1926 materials and one edition of the IBC/IRC (2009, 2012, 2015, or 2018) are permitted during testing.
A silent, nonprinting, nonprogrammable calculator is permitted for the CR-42 trade exam.
No. Licensing also requires meeting experience requirements, passing the SRE, business eligibility review, applicable background checks, and maintaining the required bond. The license is issued to the business, not the individual.
