Oklahoma Roofing Contractor Commercial Endorsement - Online Exam Prep Course

Prepare for the Oklahoma Roofing Contractor Commercial Endorsement examination with an online exam prep course focused on general roofing knowledge, low-slope roofing, architectural metal roofing systems, sheet metal flashing, moisture and energy control, repairs, reroofing, and construction safety. This preparation is designed for roofing professionals pursuing the Oklahoma Commercial Roofing Contractor Endorsement through the Oklahoma Construction Industries Board.

Oklahoma requires roofing contractors performing commercial roofing work to maintain a valid roofing contractor registration and a current commercial roofing endorsement unless a statutory exemption applies. The endorsement covers a broad range of commercial roofing activities, including installation, renovation, remodeling, reroofing, reconstruction, repair, maintenance, improvement, alteration, and waterproofing of roofs using materials such as asphalt, metal, membranes, and other roofing systems.

The current Oklahoma Roofing Contractor Commercial Endorsement technical examination is administered by PSI after the Oklahoma Construction Industries Board determines that an applicant is eligible to test. The examination contains 50 scored questions, allows 150 minutes, and requires a minimum score of 70%. Candidates currently need 35 correct answers to meet the passing standard.

The exam places significant emphasis on low-slope roofing, architectural metal roofing and sheet metal flashing, repairs and reroofing, moisture and energy control, and OSHA construction safety. Candidates should be prepared to work with roofing-system details, materials, installation practices, flashing, reroofing considerations, building-code requirements, and safety regulations while navigating several technical references efficiently.

This Oklahoma Roofing Contractor Commercial Endorsement online exam prep course is organized around the current technical examination references, including the SMACNA Architectural Sheet Metal Manual, 2018 International Building Code, multiple current NRCA Roofing Manual volumes, and 29 CFR Part 1926 OSHA.

Exam Details

The current Oklahoma Roofing Contractor Commercial Endorsement technical examination contains 50 scored questions. Candidates receive 150 minutes, or two and one-half hours, to complete the examination. A minimum score of 70% is required, which equals 35 correct answers.

General Roofing Knowledge contains five questions. Candidates should understand core roofing terminology, materials, roof-system concepts, construction practices, and fundamental principles that apply across multiple roofing systems.

Low-Slope Roofing is the largest content category with 15 questions. This section deserves substantial preparation because it represents 30% of the examination. Candidates should review membrane roofing systems, materials, insulation, flashing, drainage considerations, penetrations, edges, details, installation concepts, and common low-slope roofing practices.

Architectural Metal Roofing Systems and Sheet Metal Flashing contains nine questions. Preparation should include architectural metal roofing, sheet metal details, flashing configurations, joints, transitions, edge conditions, penetrations, and other areas covered by the SMACNA Architectural Sheet Metal Manual and applicable NRCA material.

Moisture and Energy Control contains six questions. Candidates should understand condensation control, air leakage, moisture movement, insulation, vapor-related concepts, and how roof assemblies interact with building environmental conditions.

Repairs and Reroofing contains seven questions. Candidates should review reroofing evaluation, existing roof conditions, repair considerations, removal and replacement issues, substrate conditions, flashing, drainage, and code provisions that affect reroofing work.

Safety contains eight questions. Roofing work presents significant fall and construction hazards, making OSHA preparation an important part of the examination. Candidates should be familiar with fall protection, ladders, scaffolds, personal protective equipment, material handling, access, and other construction-safety requirements relevant to roofing operations.

The examination may also include questions based on general trade knowledge and accepted industry practices. Candidates should therefore develop practical roofing knowledge in addition to learning how to locate information in the approved references.

Commercial roofing endorsement applicants also complete the separate Oklahoma Roofing Business and Law examination as part of the commercial endorsement examination process. Business and Law covers contractor estimating, project management, contracts, financial subjects, personnel, risk management, payroll, liens, and Oklahoma roofing registration requirements.

Open Book Test

The Oklahoma Roofing Contractor Commercial Endorsement technical examination is an open-book test. Candidates are responsible for bringing the approved references they intend to use at the examination center.

The current code reference is the International Building Code, 2018 Edition, with Oklahoma revisions. Because code questions are based on the specific edition listed for the examination, candidates should prepare with the 2018 edition rather than substituting another IBC edition.

The current examination reference list also includes the SMACNA Architectural Sheet Metal Manual, 2012, NRCA Roofing Manual: Membrane Roofing Systems, 2023, NRCA Roofing Manual: Metal Panel and SPF Roof Systems, 2024, NRCA Roofing Manual: Steep-Slope Roof Systems, 2025, and NRCA Roofing Manual: Architectural Metal Flashing, Condensation and Air Leakage Control, and Reroofing, 2022.

The 2025 edition of the NRCA Steep-Slope Roof Systems manual is the current listed version for the examination. The previous 2021 edition is no longer accepted for testing as of March 15, 2026.

The current reference list also permits Code of Federal Regulations - 29 CFR Part 1926 (OSHA) with the latest available amendments or the applicable PSI selections.

Approved references may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted. Strategic tabs can help candidates reach important topics such as low-slope roofing, reroofing, flashing, roof assemblies, moisture control, roof coverings, and fall protection more efficiently.

Temporary removable tabs such as Post-it notes are not permitted. References may not contain written notes before the examination, and candidates may not write in the approved references during the testing session.

Additional loose papers are not permitted with approved references. Downloaded references must be properly secured according to current testing rules. A silent, non-printing, non-programmable calculator may also be used during the examination.

With 50 questions in 150 minutes, candidates have an average of three minutes per question. Effective preparation should include knowing which book is most likely to contain a particular answer before starting a reference search.

State Requirements

The Oklahoma Construction Industries Board administers the Roofing Contractor Registration Act and the state’s roofing contractor registration and endorsement program.

All roofing contractors subject to the Act must maintain a valid roofing contractor registration. A contractor may not act as a commercial roofing contractor without a current and valid Commercial Roofing Contractor Endorsement when that endorsement is required.

A qualifying party applying for roofing contractor registration must be at least 18 years old. Oklahoma requires registration applications to include identifying, business, and compliance information specified by the Roofing Contractor Registration Act.

Commercial endorsement applicants must provide information concerning the legal entity associated with the roofing business, including applicable organizational information and information concerning officers, members, managers, partners, or other managing agents.

A roofing contractor performing commercial roofing work must maintain at least $1,000,000 in commercial general liability insurance. The Oklahoma Construction Industries Board must be listed as the certificate holder as required by state law.

Roofing contractors must also demonstrate compliance with Oklahoma workers’ compensation requirements through applicable coverage, exemption, or other authorized documentation.

Oklahoma requires roofing contractor registration and commercial endorsements to be renewed annually. Maintaining the appropriate registration and endorsement in good standing is necessary to continue offering or performing commercial roofing work.

The commercial roofing contractor scope includes installation, renovation, remodeling, reroofing, reconstruction, repair, maintenance, improvement, alteration, and waterproofing of building roofs using a variety of roofing materials. Commercial roofing contractors may supervise and manage roofing activities or personnel, supply materials, and solicit commercial roofing contracts.

Oklahoma changed the continuing education requirements for Commercial Roofing Endorsements in 2026. Beginning January 1, 2027, qualifying parties holding a Commercial Roofing Endorsement must complete four hours of approved continuing education annually for endorsement renewal.

Oklahoma also allows the Commercial Roofing Endorsement to be placed into inactive status under the current statutory framework. An inactive endorsement must still be renewed and remain compliant with applicable continuing education requirements even though the insurance requirements differ while it remains inactive.

If a candidate fails an Oklahoma roofing examination for the first time, the current testing rules require a 30-day waiting period before retesting. Subsequent failed attempts generally require a 90-day waiting period.

Test Information and Study Materials

A strong Oklahoma Roofing Contractor Commercial Endorsement study plan should follow the official examination weighting. Low-Slope Roofing, Architectural Metal Roofing Systems and Sheet Metal Flashing, and Repairs and Reroofing account for 32 of the 50 questions, making those categories especially important.

Prioritize Low-Slope Roofing. Fifteen questions come from this category. Review membrane roof systems, roof components, insulation, flashing, penetrations, drainage concepts, perimeter details, installation procedures, and common repair considerations.

Study Architectural Metal Roofing and Sheet Metal Flashing. Nine questions cover this area. Become familiar with the SMACNA manual and the applicable NRCA technical information for metal roofing, flashings, transitions, joints, edges, and penetrations.

Review Repairs and Reroofing. Seven questions focus on repair and reroofing. Study existing-system evaluation, substrate conditions, removal, replacement, flashing, drainage, moisture, and code requirements that can affect reroofing projects.

Strengthen Moisture and Energy Control knowledge. Review condensation, air leakage, insulation, moisture movement, vapor-related concepts, and how roof assemblies respond to interior and exterior environmental conditions.

Take Safety seriously. Eight questions cover safety, making OSHA one of the highest-value individual study areas. Review fall protection, ladders, scaffolds, PPE, material handling, and roofing jobsite hazards.

Use the 2018 IBC efficiently. Practice finding roof assembly, roof covering, reroofing, fire classification, insulation, and related provisions before beginning timed practice.

Learn which NRCA manual covers each subject. Efficient reference navigation can prevent wasted time searching multiple large manuals for the same answer.

Practice with permanent tabs. Mark high-value sections before the examination using only permanent tabs permitted under current testing rules.

Complete timed practice sessions. Use the 150-minute limit as your benchmark. Answer questions you know first and preserve additional time for detailed manual or code searches.

Review missed questions by category. Track errors in general roofing knowledge, low-slope roofing, architectural metal, moisture control, reroofing, and safety. Focus additional study on the categories producing the most missed questions.
