The Arizona Sheet Metal Residential / Commercial Contractor (CR-45) Exam - Online Exam Prep course is a strong fit for qualifying parties, sheet metal contractors, duct installers, architectural sheet metal workers, gutter and downspout installers, flashing installers, metal roofing professionals, ventilation workers, commercial sheet metal crews, residential sheet metal contractors, construction supervisors, project managers, business owners, and experienced tradespeople preparing for Arizona contractor licensing.

Exam Details

The Arizona CR-45 Sheet Metal residential / commercial contractor exam is administered through PSI for the Arizona Registrar of Contractors. The trade exam contains 30 questions, and candidates are allowed 75 minutes to complete the test. The minimum passing score is 70%.

The Arizona CR-45 Sheet Metal exam uses the same trade examination content as the commercial C-45 Sheet Metal and residential R-45 Sheet Metal classifications. Candidates should select the license classification that matches the work they plan to perform and follow the Arizona Registrar of Contractors licensing process for that classification.

The official content outline includes Ducts; Chimneys, Flues, and Vents; Hoods, Ventilation, and Food Service Equipment; Metal Roofing Systems, Flashing, and Architectural Metals; Gutters and Downspouts; and OSHA Safety. Ducts includes 8 items. Chimneys, Flues, and Vents includes 5 items. Hoods, Ventilation, and Food Service Equipment includes 6 items. Metal Roofing Systems, Flashing, and Architectural Metals includes 4 items. Gutters and Downspouts includes 3 items. OSHA Safety includes 4 items.

Ducts is the largest single section of the exam. Candidates should give this area significant study time because sheet metal contractors must understand duct layout, duct sizing awareness, duct materials, duct supports, joints, seams, sealing, reinforcement, flexible duct use, fittings, transitions, and construction standards. The HVAC Duct Construction Standards reference is especially important for studying duct-related topics.

Hoods, Ventilation, and Food Service Equipment is another important section. Candidates should prepare for questions related to air movement, ventilation components, hoods, exhaust systems, kitchen equipment, clearances, materials, installation practices, and safe construction procedures. Even when a contractor’s field experience is strongest in exterior sheet metal or gutters, the exam still includes ventilation and equipment-related questions.

Chimneys, Flues, and Vents may include metal flues, patented chimneys, vent materials, clearances, installation requirements, termination awareness, flashing around penetrations, and code-related concepts. Metal Roofing Systems, Flashing, and Architectural Metals may include sheet metal roofing details, roof drainage, flashing design, counterflashing, drip edges, valleys, skylight flashing, cornices, and architectural metal installation. Gutters and Downspouts may include sizing awareness, slope, outlet placement, hangers, leaders, drainage performance, and installation practices. OSHA Safety questions may involve ladders, scaffolds, fall protection, material handling, tools, personal protective equipment, cutting hazards, and jobsite hazard recognition.

Open Book Test

The Arizona CR-45 Sheet Metal exam is an open book test. Candidates are responsible for bringing their own approved references to the examination center. Approved reference materials may be highlighted, underlined, annotated, and indexed before the exam session begins. Candidates may not write, highlight, underline, or index inside the references during the examination session.

Reference books may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary tabs, removable sticky notes, and other removable tabs are not allowed and must be removed before the exam begins. Candidates may not bring loose papers or attached papers with the approved references.

If a candidate uses a permitted reference downloaded from the internet, the material must be bound before being brought into the testing center. A bound reference may be spiral bound or hole-punched and placed in a binder when allowed by the exam instructions. Candidates may use a silent, nonprinting, non-programmable calculator in the examination center.

The approved references allowed in the exam room are SMACNA Architectural Sheet Metal Manual, Code of Federal Regulations – 29 CFR Part 1926 (OSHA), HVAC Duct Construction Standards, Metal and Flexible, 2005, 3rd Edition, International Building Code, 2018, NRCA Roofing Manual: Steep Slope Roof Systems, and Sheet Metal, 2nd Edition. Candidates should use these books during preparation, become familiar with their organization, and bring only compliant reference materials into the testing center.

Open book testing rewards students who study with the references before the exam. Simply bringing the books into the testing center is not enough. Candidates should know where duct construction standards are found, where architectural sheet metal details are organized, where building code requirements may apply, where steep-slope roofing guidance appears, where OSHA safety rules are located, and how the Sheet Metal trade reference supports practical installation and fabrication knowledge.

Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. A candidate pursuing the Arizona Sheet Metal Residential / Commercial Contractor (CR-45) license should begin by confirming that the CR-45 dual classification matches the type of sheet metal work the business intends to perform. The qualifying party must complete the examination requirements connected to the license classification.

Many Arizona contractor license applicants must complete the applicable trade exam and the Arizona Statutes and Rules Training Course and Exam. The trade exam measures sheet metal and construction knowledge for the license classification, while the statutes and rules requirement covers Arizona contractor law and regulatory responsibilities. Candidates should follow the Arizona Registrar of Contractors application process for the business structure, qualifying party, experience, bonding, and supporting documents that apply to the license being pursued.

A practical preparation path begins with identifying the correct classification, reviewing the official exam content outline, gathering the approved reference books, and setting a realistic study schedule. After preparation, the candidate schedules the trade exam through PSI and follows testing center rules for identification, reference materials, calculators, personal items, and exam-room conduct.

After the required examination steps are completed, the applicant continues through the Arizona Registrar of Contractors licensing process. This may include submitting the license application, identifying the qualifying party, providing required business information, meeting bonding requirements, and satisfying other state requirements connected to the applicant and classification.

State Requirements

The Arizona CR-45 Sheet Metal classification allows the scopes of work permitted by both the commercial C-45 Sheet Metal and residential R-45 Sheet Metal classifications. This dual classification is intended for contractors who perform sheet metal work in both residential and commercial settings.

The sheet metal scope allows the licensee to install and repair sheet metal, cornices, flashings, gutters, leaders, pans, kitchen equipment, duct work, skylights, patented chimneys, metal flues, and metal roofing systems. Candidates should understand the practical work connected to the classification, including duct fabrication and installation, vent installation, flashing details, gutter and downspout systems, skylight sheet metal details, metal roofing components, architectural metal trim, hoods, ventilation, and OSHA safety practices.

Arizona issues separate contractor license classifications for commercial work, residential work, and dual residential/commercial work. The CR-45 classification is the dual residential / commercial sheet metal contractor classification. Applicants should make sure the classification fits the type of contracting work they plan to offer before moving forward with exam preparation and licensing paperwork.

Sheet metal work can affect air distribution, moisture protection, roof performance, drainage, weather resistance, ventilation, safety, and appearance. Poor duct construction can reduce air movement or create leakage. Poor flashing or gutter installation can lead to water intrusion or drainage problems. Poor vent or flue work can create safety and performance concerns. Exam preparation should reflect this responsibility by reviewing duct standards, architectural sheet metal details, steep-slope roof systems, code requirements, trade practices, and OSHA safety.
