Oklahoma Roofing Contractor Commercial Endorsement Exam Prep - Live Virtual + Self Study Training

Prepare for the Oklahoma Roofing Contractor Commercial Endorsement examination with a structured combination of live virtual instruction and self-study training. This program is designed for roofing professionals who want to add the Commercial Endorsement to an Oklahoma roofing contractor registration and need organized preparation for commercial roofing systems, low-slope roofing, architectural metal roofing, sheet metal flashing, moisture and energy control, reroofing, repairs, OSHA safety, and contractor Business and Law.

The Oklahoma Construction Industries Board regulates roofing contractor registration and the Commercial Endorsement. Oklahoma contractors performing commercial roofing work must maintain a current roofing contractor registration and the required Commercial Endorsement. The examination evaluates practical roofing knowledge across multiple roofing systems while also requiring candidates to navigate a substantial collection of open-book technical references.

Live Virtual + Self Study Training combines instructor-guided preparation with independent study time. Live virtual training helps candidates work through the major examination categories, understand how the roofing manuals and code references are organized, and focus on high-value study areas. Self-study allows additional time for reviewing commercial roofing details, practicing reference navigation, studying OSHA requirements, and preparing for Business and Law.

The technical references include the SMACNA Architectural Sheet Metal Manual, International Building Code, NRCA Roofing Manual series, and Code of Federal Regulations - 29 CFR Part 1926 (OSHA). Business and Law preparation includes Oklahoma roofing statutes and regulations, the Construction Industries Board fine schedule, workers' compensation law, lien law, and the NASCLA Contractors Guide to Business, Law and Project Management.

Exam Details

The Oklahoma Roofing Contractor Commercial Endorsement examination is administered through PSI after the Oklahoma Construction Industries Board determines that the applicant is eligible to test.

• Exam: Oklahoma Roofing Contractor Commercial Endorsement
• Number of Questions: 50 scored questions
• Passing Score: 70%
• Passing Raw Score: 35 correct answers
• Time Allowed: 150 minutes
• Testing Provider: PSI

The Commercial Endorsement examination is divided into six major technical categories:

• General Roofing Knowledge: 5 questions

Low Slope Roofing is the largest individual examination category with 15 questions. Candidates should devote substantial study time to commercial membrane roofing systems, roof assemblies, materials, installation principles, details, drainage considerations, and practices associated with low-slope commercial roofs.

Architectural Metal Roofing Systems and Sheet Metal Flashing contains nine questions. Preparation should include metal roofing systems, flashing details, sheet metal practices, roof transitions, penetrations, edges, joints, and other architectural metal applications. The SMACNA Architectural Sheet Metal Manual is particularly important for understanding standard sheet metal details and construction practices.

Repairs and Reroofing contains eight questions. Candidates should understand assessment of existing roofing conditions, reroofing considerations, repair methods, roof preparation, compatibility of roofing materials, and conditions that can influence whether a roof system is repaired, recovered, or replaced.

Safety contains seven questions and uses OSHA construction requirements. Roofing professionals should prepare for fall protection, ladders, scaffolds, personal protective equipment, material handling, jobsite hazards, and other construction-safety topics applicable to commercial roofing operations.

Commercial roofing candidates also prepare for the Oklahoma Roofing Business and Law examination.

• Business and Law Questions: 50 scored questions
• Passing Score: 70%
• Passing Raw Score: 35 correct answers
• Time Allowed: 120 minutes

The Business and Law examination covers bidding and estimating, project management and supervision, contracts, financial management, labor and personnel, risk management, payroll and payroll taxes, and licensing requirements. Candidates should prepare for both general contractor business practices and Oklahoma-specific roofing regulations.

Open Book Test

The Oklahoma Roofing Contractor Commercial Endorsement examination is an open-book test. Candidates may bring approved reference materials into the examination center while following PSI requirements for permitted books and materials.

The examination reference list includes the SMACNA Architectural Sheet Metal Manual, 2012; International Building Code, 2018 with Oklahoma revisions; 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; NRCA Roofing Manual: Architectural Metal Flashing, Condensation and Air Leakage Control, and Reroofing, 2022; and Code of Federal Regulations - 29 CFR Part 1926 (OSHA) with the latest available amendments.

Because it is now after March 15, 2026, the 2021 edition of the NRCA Roofing Manual: Steep Slope Roof Systems is no longer permitted for this examination. Candidates should prepare with the 2025 edition.

Reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs are allowed. Temporary removable tabs such as Post-it notes are not permitted. Candidates are also prohibited from writing in the references before or during the examination session.

Open-book does not mean candidates have time to search every manual from beginning to end. The exam includes several large roofing references, so successful preparation should focus heavily on knowing which book contains a particular subject and how each manual is organized.

A productive reference-navigation method is to identify the roofing system or technical subject first, select the correct reference, find the applicable section or detail, and then apply that information to the question. Practicing this process under timed conditions helps candidates build familiarity with the technical books.

Licensing Steps

The Oklahoma Construction Industries Board administers roofing contractor registration and the Commercial Endorsement. A roofing contractor registration that is in good standing is required before a Commercial Endorsement can be approved.

1. Obtain an Oklahoma Roofing Contractor Registration. Complete the applicable state registration process before pursuing the Commercial Endorsement.
2. Maintain the roofing registration in good standing. Commercial endorsement eligibility is connected to a current Oklahoma roofing contractor registration.
3. Apply for the Commercial Endorsement. Submit the required application and supporting documentation to the Oklahoma Construction Industries Board.
4. Meet commercial insurance requirements. Contractors performing commercial roofing work must satisfy the applicable commercial general liability insurance requirements.
5. Provide workers' compensation compliance documentation. Applicants must demonstrate compliance with applicable Oklahoma workers' compensation requirements or a qualifying exemption.
6. Receive examination eligibility. Once the application is approved, the qualifying party receives information for scheduling the required examination.
7. Schedule the PSI examination. Arrange the examination date, time, and location with the testing provider.
8. Prepare for the Commercial Endorsement exam. Study roofing systems, low-slope roofing, architectural metal, flashing, moisture control, reroofing, repairs, and OSHA safety.
9. Prepare for Roofing Business and Law. Review estimating, contracts, financial management, personnel, risk management, payroll, liens, workers' compensation, and Oklahoma roofing regulations.
10. Complete the required examinations. Achieve the required passing scores as part of the Commercial Endorsement process.
11. Maintain registration and endorsement. Commercial roofing contractors must keep both their roofing contractor registration and Commercial Endorsement current.

State Requirements

Oklahoma requires roofing contractors to obtain a valid roofing contractor registration through the Construction Industries Board to engage in or offer roofing-related services in the state. Contractors who perform commercial roofing work must also maintain the Commercial Endorsement.

A roofing contractor registration that allows residential roofing work and is in good standing is required before the Commercial Endorsement can be approved. The Commercial Endorsement is an additional qualification for contractors performing commercial roofing work.

Commercial roofing contractors must provide evidence of commercial general liability insurance of at least $1,000,000. Proof of roofing coverage must meet Oklahoma Construction Industries Board requirements. Applicants and registrants must also comply with applicable workers' compensation requirements.

The qualifying party is responsible for the roofing operation associated with the registration and endorsement. Oklahoma roofing rules include requirements concerning supervision and control of the roofing firm's operations and compliance with the Roofing Contractor Registration Act and associated regulations.

If a candidate fails the Commercial Endorsement examination, Oklahoma requires a 30-day waiting period after the first failed attempt. After subsequent failed attempts, the waiting period is 90 days.

Qualifying parties holding a Commercial Endorsement are subject to continuing-education requirements. Current Oklahoma requirements call for four hours of approved commercial roofing continuing education every three years, or 36 months, after the applicable initial period following passage of the endorsement examination.

Test Information and Study Materials

A strong Oklahoma Roofing Contractor Commercial Endorsement study plan should divide preparation among technical roofing systems, safety, open-book navigation, and Business and Law.

Prioritize low-slope roofing. With 15 questions, Low Slope Roofing represents 30% of the 50-question technical examination. Candidates should spend significant study time with the NRCA membrane roofing materials and commercial low-slope concepts.

Study architectural metal and flashing. Nine questions address Architectural Metal Roofing Systems and Sheet Metal Flashing. Practice using both the SMACNA manual and applicable NRCA material so common flashing and metal-roof details are easier to locate.

Review repairs and reroofing. Eight questions focus on this area. Study existing-roof assessment, repair considerations, reroofing practices, material compatibility, and details associated with roof replacement and recovery.

Prepare for moisture and energy control. Understand condensation, air leakage, moisture movement, insulation-related considerations, and how roof assemblies respond to environmental conditions.

Do not overlook OSHA. Safety accounts for seven questions. Roofing work involves significant fall hazards, so fall protection should be a major part of OSHA preparation along with ladders, scaffolds, PPE, and general construction safety.

Practice timed reference navigation. Candidates have 150 minutes for 50 technical questions. Familiarity with the reference collection can reduce time spent searching and provide more time for interpreting difficult roofing questions.

Prepare separately for Business and Law. The Roofing Business and Law exam is a separate 50-question examination. Focus on estimating, project supervision, contracts, finances, personnel, risk management, payroll, licensing requirements, Oklahoma roofing laws, workers' compensation, liens, and contractor regulations.
