AZ-ROOF Requirements Overview
Getting licensed to run roofing work in Arizona isn't a single test you sit down and take. It's a sequence of eligibility checks, documentation, and exams administered under the Arizona Registrar of Contractors (AZ ROC), with the trade knowledge exam delivered through PSI. If you're researching Arizona roofing license requirements for 2026, you're really looking at three separate but connected tracks: personal experience qualification for whoever will serve as the license's qualifying party, business-entity eligibility for the company that will hold the license, and the trade competency exam itself - officially CR-42 Roofing (Residential/Commercial), which this site refers to by its identifier, AZ-ROOF.
This guide breaks down exactly what you need to qualify, in the order the Registrar of Contractors actually evaluates it. For a deeper dive into what the exam covers once you're eligible to sit for it, see our AZ-ROOF Exam Domains 2026: Complete Guide to All 6 Content Areas.
The Statutory Experience Baseline
Before anyone schedules CR-42 at a PSI test center, the person acting as qualifying party has to clear a statutory experience threshold. Arizona's baseline requirement is four years of trade experience, with at least two of those four years falling within the most recent ten years. This isn't a suggestion - it's the floor the Registrar of Contractors uses to determine whether an applicant even gets to move forward toward exam scheduling.
A few nuances matter here:
- The four-year requirement can, in certain circumstances, be offset through authorized training-credit provisions recognized by the Registrar.
- Reduction provisions exist for applicants with specific qualifying backgrounds, though these are evaluated case by case.
- Documentation-waiver pathways exist for narrow situations, but they don't eliminate the need to substantiate your trade background in some form.
Because these provisions are statutory and administratively interpreted, don't assume you qualify for a reduction or waiver without confirming it directly against the current rules published by the AZ ROC. Treat the four-year/two-in-ten-year baseline as your default planning assumption unless you have documented proof otherwise.
Key Takeaway
Start compiling verifiable proof of trade experience - pay stubs, W-2s, prior licenses, employer letters - well before you plan to schedule CR-42. Experience documentation delays are one of the most common reasons applications stall.
Business Eligibility and the Qualifying Party
Passing the trade exam is necessary but not sufficient. The AZ ROC evaluates the licensing application at the business level. That means, alongside the qualifying party's experience and exam results, the Registrar reviews:
- Business structure eligibility - the entity type applying for licensure must meet applicable state requirements.
- Background checks applicable to owners, officers, or the qualifying party, as required under Arizona licensing rules.
- Bonding - the business must obtain and maintain the required contractor's bond as a condition of holding an active license.
Because the license is tied to the business rather than the individual, a qualifying party leaving a company can create a licensing gap that the business must resolve - often by designating a new qualifying party who independently meets the experience and exam requirements. If you're evaluating whether pursuing this credential path is worth the investment of time before you even get to the exam stage, our analysis in Is the AZ-ROOF Certification Worth It? Complete ROI Analysis 2026 walks through the tradeoffs.
CR-42 Exam Structure and Domains
Once experience is documented and you're cleared to test, the trade knowledge component is where most candidates focus their energy - and rightly so, since it's the most concrete, study-able piece of the entire licensing process. CR-42 Roofing (Residential/Commercial), tracked on this site under the AZ-ROOF identifier, is administered by PSI and structured as follows:
- 50 total questions
- 120-minute time limit
- 70% passing score
PSI's published outline breaks those 50 questions across six content areas, with item counts of 5, 5, 20, 10, 6, and 4 respectively. That distribution tells you almost everything about where to spend your study hours:
Domain 1: Estimating and Plan Reading
Covers reading roofing plans and specifications and translating them into material and labor estimates.
- Roughly 5 questions on the exam
Domain 2: Surface Preparation and Planning
Focuses on preparing decks and substrates and planning a job before installation begins.
- Roughly 5 questions on the exam
Domain 3: Steep and Low Slope Roofing, including BUR and Waterproofing
This is the largest content area on CR-42 by a wide margin, covering built-up roofing (BUR) systems, low-slope membrane work, steep-slope shingle and tile systems, and waterproofing details.
- Roughly 20 questions - 40% of the entire exam
Domain 4: Roofing Components
Covers flashing, vents, drains, underlayment, and the individual components that make up a complete roofing assembly.
- Roughly 10 questions on the exam
Domain 5: Safety
Focuses on jobsite safety practices, much of which draws directly from OSHA regulations relevant to roofing work.
- Roughly 6 questions on the exam
Domain 6: Repairs and Reroofing
Covers diagnosing existing roof problems and executing repair or reroofing scopes correctly.
- Roughly 4 questions on the exam
Because Domain 3 alone accounts for 20 of the 50 questions, a candidate who under-prepares on BUR systems and waterproofing details is taking on outsized risk relative to every other content area combined. For a question-by-question breakdown of what each domain actually tests, read AZ-ROOF Exam Domains 2026: Complete Guide to All 6 Content Areas.

Approved References and Testing-Day Rules
One requirement candidates frequently misunderstand is the exam's reference policy. CR-42 is partly open book, but the rules around what you can bring - and how it can be marked up - are specific.
Permitted in the exam room:
- The listed OSHA 29 CFR Part 1926 materials relevant to the exam
- IBC or IRC editions - 2009, 2012, 2015, or 2018
Not permitted in the exam room, despite being useful study materials:
- Roofing Construction & Estimating
- The listed NRCA manuals
These two are study-only references. You should absolutely use them while preparing, but don't plan on having them at the testing center - bringing a study-only reference in place of an approved one will not be allowed.
On markup rules: pre-existing annotations, highlighting, and permanent tabs in your approved references are allowed. However, loose papers, temporary tabs, and writing inside your references during the actual test session are prohibited. Plan your tabbing and highlighting strategy well ahead of test day, not the night before.
A silent, nonprinting, nonprogrammable calculator is permitted for estimating-related questions.
Key Takeaway
Build your approved reference book (OSHA 1926 materials plus your chosen IBC/IRC edition) with permanent tabs and highlighting well before exam day - you won't be able to add loose notes once testing starts.
The Statutes and Rules Examination
Separate from CR-42 is the Statutes and Rules Examination (SRE), a distinct licensing component that every qualifying party must also pass. The SRE and the trade exam test different bodies of knowledge - one is roofing craft competency, the other is Arizona contractor law and administrative rules - and both count toward the requirement that required written examinations generally be taken within two years before application.
That two-year window is an important planning constraint. If you pass CR-42 early but delay your business application, your exam results may age out before you finish assembling the rest of your licensing package. Sequence your experience documentation, business formation, and exam scheduling so that everything lands inside that window.
Fees, Bonds and Renewal Timing
Requirements don't end once the license is issued - maintaining it involves ongoing fee and bonding obligations. For a Specialty Dual license, the standard renewal cost structure is:
| Component | Amount | Frequency |
|---|---|---|
| Renewal fee | $380 | Every 2 years |
| Recovery-fund assessment | $270 | Every 2 years |
| Total per cycle | $650 | Every 2 years |
On top of renewal fees, remember that the business must maintain its required bond continuously - licensure isn't a one-time transaction.

Mapping Your Prep to the Requirements Timeline
Because eligibility, exam scheduling, and application submission all interact with the two-year exam-validity window, it helps to treat your study plan as part of the requirements process, not a separate activity. A simple way to sequence it:
Domain 3 Deep Dive
- Study BUR systems, low-slope membranes, and waterproofing details first since this domain carries 20 of 50 questions
- Build your tabbed reference set using approved OSHA and IBC/IRC materials
Roofing Components and Repairs/Reroofing
- Cover flashing, vents, drains, and underlayment (Domain 4)
- Study diagnosing and correcting existing roof problems (Domain 6)
Estimating, Surface Prep, and Safety
- Round out the smaller domains - plan reading, substrate prep, and OSHA-based safety questions
Full Practice and Reference Rehearsal
- Take full-length timed practice sessions against the 120-minute limit
- Rehearse navigating your approved references quickly under time pressure
This kind of weighted scheduling matters more for CR-42 than generic study advice would suggest - because the domain breakdown is so lopsided toward Domain 3, spending equal time across all six areas is a mistake.

Frequently Asked Questions
The statutory baseline is four years of trade experience, with at least two of those years occurring within the last ten years. Training-credit, reduction, and documentation-waiver provisions may adjust this for specific applicants, so confirm your situation against current Registrar of Contractors rules.
CR-42 Roofing (Residential/Commercial) is the official exam, administered by PSI, and AZ-ROOF is simply the identifier this site uses for it. It's one required component among several, alongside the Statutes and Rules Examination and business eligibility review.
No. NRCA manuals and Roofing Construction & Estimating are study-only references. Only the listed OSHA 29 CFR Part 1926 materials and an approved IBC/IRC edition (2009, 2012, 2015, or 2018) are permitted during the actual exam.
Required written examinations generally must be taken within two years before application, so plan your exam scheduling and application timeline together rather than passing the exam far in advance of applying.
The license belongs to the business entity, not the individual qualifying party. This affects continuity planning if a qualifying party leaves the company, since the business may need a new qualifying party who independently meets experience and exam requirements.
Meeting Arizona's roofing licensing requirements is as much about sequencing paperwork correctly as it is about mastering roofing craft knowledge. Once your experience documentation and business eligibility are lined up, the trade exam itself becomes the most controllable variable in the process - and the one most within your power to prepare for thoroughly.
