Arizona Roofing Residential / Commercial Contractor (CR-42) Books Allowed into Exam Package

The Arizona Roofing Residential / Commercial Contractor (CR-42) Books Allowed into Exam Package is designed for candidates preparing for the Arizona CR-42 Roofing residential/commercial contractor trade exam who need the approved exam-room references in one organized package. This package includes the books provided for this exam-room reference set: Code of Federal Regulations - 29 CFR Part 1926 (OSHA), International Building Code, 2018, and International Residential Code for One- and Two-Family Dwellings, 2018.

The Arizona CR-42 Roofing classification is a residential/commercial contractor classification for roofing work within the scope of the license. It covers work related to weatherproofing, roof accessories, roof tile, shingles, shakes, slate, metal roofing systems, urethane foam, roof insulation, and roof coatings on or above the roof deck. Candidates preparing for this exam should be ready to study estimating, plan reading, roof surface preparation, steep-slope roofing, low-slope roofing, built-up roofing, waterproofing, roofing components, safety, repairs, and reroofing.

This books allowed into exam package focuses on the references that may be brought into the examination center for the Arizona CR-42 roofing exam. Open-book testing gives candidates access to approved materials, but it does not remove the need for preparation. Candidates still need to understand roofing systems, read questions carefully, know how to identify the correct reference, and locate code or safety information quickly during a timed examination.

The Code of Federal Regulations - 29 CFR Part 1926 (OSHA) supports construction safety preparation for roofing work. Roofing contractors often work at height, handle materials on slopes, use ladders and scaffolds, operate tools, manage fall hazards, and coordinate with other trades. OSHA Part 1926 helps candidates study jobsite safety topics that may appear on the exam and that are important for responsible roofing work.

The International Building Code, 2018 supports preparation for commercial building code topics that may connect to roofing systems, roof assemblies, roof coverings, fire classification, weather protection, insulation, drainage, structural considerations, materials, and general code navigation. The International Residential Code for One- and Two-Family Dwellings, 2018 supports preparation for residential roofing topics, one- and two-family dwelling requirements, roof assemblies, underlayment, flashing, roof coverings, ventilation, ice barrier provisions where applicable, and residential code organization.

Roofing contractors need practical field knowledge and exam-focused reference skills. A candidate may already know how to install shingles, repair flashing, apply coatings, or coordinate a reroof, but licensing exam questions may require a different kind of thinking. The test may ask about code language, safety standards, estimating, roofing materials, slope conditions, roof components, waterproofing, repairs, and planning. Studying with the approved books helps connect real-world roofing experience with the exam format.

Exam Details

The Arizona Roofing Residential / Commercial Contractor (CR-42) trade exam is part of the Arizona contractor licensing process. The exam is administered through PSI for the Arizona Registrar of Contractors. The reference material listed for the examination is used to prepare exam questions, and the exam may also include questions based on trade knowledge and general industry practices.

The Arizona CR-42 trade exam contains 50 questions. The minimum passing score is 70%, and the time allowed is 120 minutes. Candidates should manage time carefully because the exam covers both roofing trade knowledge and reference-based code or safety topics. With 50 questions in 120 minutes, candidates have a little over two minutes per question on average.

The exam content outline includes the following subject areas:

• Estimating and Plan Reading: 5 items
• Surface Preparation and Planning: 5 items
• Steep and Low Slope Roofing, including BUR and Waterproofing: 20 items
• Roofing Components: 10 items
• Safety: 6 items
• Repairs and Reroofing: 4 items

For code questions, candidates should use the exact code editions listed for the examination. This package includes the International Building Code, 2018 and the International Residential Code for One- and Two-Family Dwellings, 2018. Safety-related questions may be supported by Code of Federal Regulations - 29 CFR Part 1926 (OSHA).

Candidates may use a silent, nonprinting, non-programmable calculator in the examination center. This can be useful for estimating, roof area calculations, material quantities, waste factors, slope-related measurements, and other construction math questions. Approved references should be organized before test day with permitted highlighting, underlining, annotations, indexing, and permanent tabs.

Open Book Test

The Arizona Roofing Residential / Commercial Contractor (CR-42) trade exam is an open-book test with specific rules for approved references. This package includes the books allowed into the examination center for the Arizona CR-42 books allowed into exam package: Code of Federal Regulations - 29 CFR Part 1926 (OSHA), International Building Code, 2018, and International Residential Code for One- and Two-Family Dwellings, 2018.

Candidates are responsible for bringing their own approved references to the examination center. Reference materials may be highlighted, underlined, annotated, and indexed before the examination session. During the examination session, candidates may not write, highlight, underline, or index in the references.

Permanent tabs are allowed. Temporary tabs, including Post-it style tabs or other removable tabs that can be removed without tearing the page, are not allowed and must be removed before the exam begins. Candidates may not bring additional papers, whether loose or attached, with the approved references.

Downloaded reference materials may be brought into the testing center when properly bound. Spiral binding or a hole-punched binder format may be used when permitted by testing rules. Book preparation should be completed before the exam appointment so the candidate can focus on answering questions instead of correcting reference problems at the testing center.

Open-book preparation should include regular practice with tables of contents, indexes, definitions, chapter headings, roofing provisions, code tables, and OSHA safety standards. The IBC, IRC, and OSHA references are technical books. A clear permanent tabbing system and repeated timed lookup practice can help candidates move through exam questions more efficiently.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Candidates pursuing the Arizona CR-42 Roofing Residential / Commercial Contractor license should begin by confirming that this classification matches the roofing work they plan to advertise, contract for, supervise, and perform.

The qualifying party is the person who qualifies the license by meeting the knowledge, experience, and examination requirements for the classification. For many applicants, the qualifying party must complete the required trade exam and the Arizona Statutes and Rules requirement unless an approved waiver applies.

Common licensing steps include selecting the correct license classification, identifying the qualifying party, completing the required examination or approved waiver process, meeting the Arizona Statutes and Rules requirement when required, forming or registering the business entity when applicable, obtaining the required bond, completing background checks for required individuals, providing government-issued identification, and submitting the completed license application with required documents and fees.

Applicants using an LLC or corporation should make sure the business entity is properly formed or registered before submitting the contractor license application. The legal business name should match across entity records, bond documents, application paperwork, and future advertising. Consistent documentation helps reduce delays during application review.

Passing the trade exam is an important step, but it does not automatically issue the contractor license. Applicants must complete the full Arizona Registrar of Contractors application process and meet all licensing requirements for the classification. Candidates should prepare for the exam while also staying organized with business records, bond information, background checks, identification, and application paperwork.

State Requirements

The Arizona CR-42 Roofing classification allows the licensee to apply or install weatherproofing, including materials such as asphaltum, pitch, tar, felt, glass fabric, or flax, and roof accessories such as flashing, valleys, gravel stops, or sheet metal as required to install or repair roofing systems. Covered roofing work may include roof tile, shingles, shakes, slate, metal roofing systems, urethane foam, roof insulation, and coatings on or above the roof deck.

The classification also allows the licensee to replace up to three sheets, or 96 square feet, of plywood on the roof substrate. It also allows installation of new skylights or replacement of existing skylights where the work does not require changes to the roof framing or roof structure.

Because CR-42 is a residential/commercial classification, it is designed for contractors who need authority to perform covered roofing work in both residential and commercial settings within the limits of the classification. Arizona also issues residential-only, commercial-only, and dual classifications for different trades and fields of construction.

Roofing work may involve steep-slope systems, low-slope systems, roof deck conditions, underlayment, flashing, valleys, roof insulation, coatings, roof accessories, drainage, waterproofing, repairs, reroofing, and jobsite safety. Contractors should understand the license scope and avoid contracting for work outside the authorized classification.

Some roofing projects may require coordination with other properly licensed contractors when work involves structural framing changes, electrical work, plumbing, mechanical equipment, solar systems, extensive deck replacement, or other specialty work outside the CR-42 scope. Understanding license boundaries is part of responsible contracting and helps keep the business aligned with Arizona licensing requirements.

Test Information and Study Materials

The Arizona CR-42 exam covers estimating, plan reading, surface preparation, roofing systems, roofing components, safety, repairs, and reroofing. A strong study plan should follow the exam content outline and give attention to each subject area. Candidates should avoid studying only the roofing systems they install most often because the exam includes both steep-slope and low-slope roofing topics.

For estimating and plan reading, candidates should review roof measurements, slope, pitch, squares, material quantities, waste factors, plan symbols, roof layouts, valleys, hips, ridges, penetrations, and roof area calculations. Estimating questions may require both construction math and practical roofing judgment.

For surface preparation and planning, candidates should study roof deck inspection, substrate condition, cleaning, moisture concerns, removal of existing materials, preparation for coatings, underlayment planning, flashing planning, weather considerations, staging, safety planning, and project sequencing. Good preparation before installation helps prevent failures and supports better workmanship.

For steep and low slope roofing, including BUR and waterproofing, candidates should review shingles, tile, shakes, slate, metal roofing systems, built-up roofing, membranes, coatings, underlayment, waterproofing, roof slope requirements, drainage, fasteners, adhesives, and installation methods. This is the largest exam content area, so it deserves focused study time.

For roofing components, candidates should study flashing, valleys, drip edges, gravel stops, roof insulation panels, penetrations, vents, skylights, roof accessories, sheet metal details, ridge components, fasteners, drainage components, and weather-resistant details. Roofing components often determine how well a system manages water, wind, heat, and movement.

For safety, candidates should work directly with OSHA 29 CFR Part 1926. Roofing projects may involve fall hazards, ladders, scaffolds, material hoisting, tools, heat exposure, sharp materials, power equipment, roof edges, fragile surfaces, and changing weather conditions. Safety preparation supports both exam readiness and responsible jobsite practice.

For repairs and reroofing, candidates should review leak investigation, damaged roof coverings, deck repair limits, flashing repair, reroof preparation, material compatibility, removal methods, overlay considerations, skylight replacement limits, coatings, and final inspection. Repair and reroofing questions may test practical field judgment as well as code and scope awareness.
