AZ-ROOF Certification

What the AZ-ROOF Certification Actually Covers

AZ-ROOF is the site identifier PSI uses for the Arizona Registrar of Contractors' CR-42 Roofing trade exam, which covers both residential and commercial roofing work. If you're preparing for a qualifying party role on a roofing contractor's license, this is the exam PSI administers on behalf of the AZ ROC to confirm you know the trade well enough to run jobs, supervise crews, and sign off on work that inspectors and homeowners will rely on for decades.

It's easy to confuse "AZ-ROOF" with other credentials that share the acronym in unrelated industries. On this site, AZ-ROOF means exactly one thing: the Arizona Roofing Contractor Trade Exam tied to CR-42. Everything below reflects that exam's structure, not a generic contractor test. For a broader orientation before you dive into scheduling, the What Is AZ-ROOF? overview and the AZ-ROOF Meaning explainer are useful starting points.

Exam Format: Questions, Timing, and Scoring

PSI's CR-42 exam is built around a fixed, straightforward format: 50 questions, a 120-minute window, and a 70% passing score. That works out to roughly two and a half minutes per question if you use the full time, though most candidates who've studied the material move faster through the easier estimating and safety items and slow down on scenario-based roofing systems questions.

PSI revised the exam outline on June 8, 2023, so any prep material referencing an older blueprint may not match current weighting. If you're working from an older study guide, cross-check it against the current outline before trusting its domain percentages.

The Six Domains, By Item Count

PSI's published item counts for CR-42 are 5, 5, 20, 10, 6, and 4, mapped to six content domains. Understanding where the weight sits is the single most useful thing you can do before opening a textbook. For a deeper walkthrough of each domain's subtopics, see the AZ-ROOF Exam Domains 2026: Complete Guide to All 6 Content Areas.

If you're still deciding how seriously to take each section, the How Hard Is the AZ-ROOF Exam? Complete Difficulty Guide 2026 breaks down where most candidates actually lose points.

What You Can Bring Into the Exam Room

CR-42 is partly open book, which surprises some first-time candidates. Approved references include the listed OSHA 29 CFR Part 1926 materials and the IBC/IRC in the 2009, 2012, 2015, or 2018 editions. You're allowed to bring these into the test session, and pre-existing annotations, highlighting, and permanent tabs in those references are permitted.

What's not allowed: loose papers, temporary tabs, or writing in your references during the actual test. Roofing Construction & Estimating and the listed NRCA manuals are valuable while you study, but they are study-only resources - you cannot bring them into the exam room.

Because the open-book rules are specific and easy to get wrong, it's worth reviewing them closely before you schedule. The AZ-ROOF Cheat Sheet 2026: One-Page Review of Must-Know Facts is a fast way to confirm the reference and calculator rules right before your session.

How AZ-ROOF Fits Into Your ROC License

Passing CR-42 is one piece of a larger licensing process run by the Arizona Registrar of Contractors. It is not the finish line by itself. Separately, you'll also need to pass the Statutes and Rules Examination (SRE), which tests your knowledge of Arizona contracting law rather than roofing technique.

On the experience side, the qualifying party must generally show four years of trade experience, including at least two within the last ten years, though authorized training-credit, reduction, and documentation-waiver provisions can adjust that baseline depending on your background. Required written examinations generally must be taken within two years before you apply, so timing your CR-42 attempt relative to your application matters.

Beyond the exams, licensing involves business eligibility review, applicable background checks, and maintaining the required bond. It's also worth remembering that the license attaches to the business entity, not to the individual qualifying party - a detail that affects how you plan if you ever change employers or start your own company. The AZ-ROOF Requirements 2026: Eligibility, Prerequisites & How to Qualify guide walks through these pieces in more detail, and AZ-ROOF Passing Score 2026: Exactly What You Need to Pass covers the scoring mechanics specifically.

Fees and Renewal Mechanics

Once licensed, ongoing costs don't stop at the exam fee. The standard Specialty Dual renewal totals $650 per two-year cycle, made up of a $380 renewal fee plus a $270 recovery-fund assessment. Budgeting for this recurring cost matters just as much as budgeting for your initial exam attempt, especially if you're weighing the certification against other paths into the trade.

Who Actually Needs This Certification

CR-42 exists for people stepping into the qualifying party role for a roofing contracting business licensed in Arizona - the person whose trade knowledge and experience the state relies on to license that company. That includes roofing crew leads and superintendents moving toward ownership, established roofers relocating to Arizona who need to requalify under the ROC, and business owners who want to serve as their own qualifying party rather than hiring one.

It's less relevant to entry-level installers who aren't pursuing a license, though understanding the domains early can still shape a stronger career path. If you're mapping out where roofing licensure can take you, AZ-ROOF Jobs and AZ-ROOF Training both cover the practical side of that transition.

Building a Domain-Aware Study Schedule

Generic study techniques only help if they're pointed at the right material. Given that Domain 3 alone accounts for 20 of the 50 questions, your schedule should weight time accordingly rather than splitting it evenly across all six domains.

Running full-length practice sessions under the real 120-minute limit is one of the best ways to confirm your pacing before test day - you can start building that habit on the AZ-ROOF practice test platform. For a more detailed week-by-week plan than the outline above, the AZ-ROOF Study Guide 2026: How to Pass on Your First Attempt goes deeper on resource selection and review cadence.
