Oklahoma Construction Industries Board • PSI Commercial Roofing Endorsement • 50 Questions • 150 Minutes • 70% Passing • Roofing Business and Law • Open Book
Getting ready to become an Oklahoma roofing contractor? This guide explains the state's roofing registration requirements, Commercial Roofing Contractor Endorsement examination, Business and Law test, approved reference books, roofing safety, and related study products available from Contractor Exam Preps.
A roof has one of the most important jobs in a building.
It keeps rain, wind, hail, and other weather outside.
When a roof fails, homeowners and building owners discover just how quickly water can turn a normal day into a very expensive adventure.
That is why roofing contractors must understand more than basic shingle installation.
They need knowledge of low-slope roofing, membrane systems, architectural metal roofing, flashing, insulation, ventilation, drainage, roof repairs, and safety.
Contractors also need to follow registration, insurance, and business requirements.
Oklahoma regulates roofing contractors through the Oklahoma Construction Industries Board.
The requirements depend on whether a contractor performs residential or commercial roofing.
Oklahoma requires roofing contractor registration.
The Oklahoma Roofing Contractor Registration Act establishes the registration requirements for roofing contractors performing roofing services in the state.
For commercial roofing work, the contractor must also obtain a Commercial Roofing Contractor Endorsement.
That endorsement requires approval and examinations.
The endorsement is not the same thing as ordinary roofing registration.
Residential roofing currently follows registration rules, although Oklahoma has adopted additional residential endorsement requirements that begin during the 2027 transition period.
Therefore, contractors must carefully choose the correct licensing and examination pathway.
The Oklahoma Construction Industries Board, commonly called the CIB, regulates roofing registrations and endorsements.
The Board oversees registration, examinations, renewals, and compliance with roofing industry regulations.
PSI administers the commercial endorsement examinations after the applicant receives authorization.
The Board determines whether the applicant meets the requirements for registration and commercial endorsement approval.
The Commercial Roofing Contractor Endorsement allows an appropriately registered roofing contractor to perform commercial roofing work within the authorized scope.
Commercial roofing work may involve office buildings, retail facilities, warehouses, industrial properties, and other buildings.
The work may include installation, renovation, remodeling, reroofing, repair, maintenance, alteration, reconstruction, and waterproofing of roofs.
Commercial roofers may work with membrane roofing, asphalt products, metal panels, shingles, and other recognized roofing materials.
They must also comply with applicable building codes and industry standards.
The official PSI Commercial Roofing Contractor Endorsement examination contains 50 questions.
Candidates have 150 minutes, or two hours and thirty minutes.
The passing requirement is 70%.
That means a candidate must answer at least 35 questions correctly.
The examination is open book.
However, only approved reference materials may be brought to the examination center.
Yes.
Commercial roofing endorsement applicants must pass both the technical examination and the separate Roofing Business and Law examination.
The Roofing Business and Law exam contains 50 questions.
Candidates have 120 minutes, or two hours.
The passing score is 70%, equal to 35 correct answers.
The examination covers contracting, estimating, management, insurance, taxes, labor law, contracts, and state licensing requirements.
According to the current PSI examination outline, the Commercial Roofing Contractor Endorsement test includes six subject categories.
The six categories total 50 questions.
The largest category is Low Slope Roofing, with fifteen questions.
Architectural Metal Roofing and Flashing follows with nine questions.
Repairs and Reroofing includes eight.
These three subjects account for 32 of the 50 technical questions.
General Roofing Knowledge contains five questions.
Study basic roofing terminology, roof slopes, roof assemblies, roofing materials, and common installation principles.
Review the differences between low-slope and steep-slope systems.
Learn how roofing materials work together to protect the building.
Study roof decks, underlayment, insulation, flashing, drainage, and weather protection.
Review roof covering fire classifications and wind-resistance requirements.
Understand the purpose of proper roof design and installation.
Low Slope Roofing is the largest technical examination category, with fifteen questions.
Study built-up roofing, modified bitumen, thermoset membranes, thermoplastic membranes, and liquid-applied roofing systems.
Review roof decks, substrates, insulation, attachment methods, seams, flashing, and drainage.
Understand how insulation and vapor control affect roofing performance.
Learn how roof slope and drainage influence material selection.
Study the NRCA Roofing Manual: Membrane Roofing Systems, 2023.
This manual is a primary reference for low-slope roofing preparation.
Architectural Metal Roofing Systems and Sheet Metal Flashing contains nine questions.
Review metal roof panels, standing-seam systems, clips, fasteners, metal properties, and installation details.
Study architectural sheet metal fabrication and installation.
Learn why different metals may react when they contact one another.
Review corrosion protection, expansion, contraction, flashing, drainage, and roof edge details.
Understand the difference between structural and architectural metal roof panels.
The approved reference list includes the SMACNA Architectural Sheet Metal Manual, 2012, and the NRCA Metal Panel and SPF Roof Systems Manual, 2024.
Moisture and Energy Control contains six questions.
Study roof insulation, vapor retarders, air leakage, condensation, and moisture management.
Review R-values and thermal performance concepts.
Understand how moisture can enter a roofing assembly.
Learn why improper vapor control can create problems inside a roof system.
Study common insulation materials and methods.
Review flashing and weather barriers as part of the complete building envelope.
Repairs and Reroofing contains eight questions.
Study roof inspections, material deterioration, existing roof conditions, moisture damage, and repair methods.
Understand the difference between roof recovery and full replacement.
Review when an existing roof system may need to be removed.
Study how damaged substrates can affect new materials.
Learn the importance of repairing flashing, seams, penetrations, and drainage defects.
Review code requirements for reroofing and roofing repairs.
Safety accounts for seven questions.
Roofing work can expose workers to fall hazards, ladders, scaffolds, changing weather, hot work, and dangerous equipment.
Study OSHA 29 CFR Part 1926.
Review fall protection, personal fall arrest systems, guardrails, warning lines, ladders, and scaffolds.
Study material handling, protective equipment, and fire prevention.
Understand the responsibilities of employers and supervisors.
Safety is one of those subjects where a passing test score is nice, but safe work practices are essential.
Oklahoma is transitioning to newer international building codes.
The Commercial Roofing Contractor Endorsement examination currently permits either the 2018 International Building Code or the 2024 International Building Code during the transition period.
Oklahoma's adopted building code update took effect September 14, 2026.
There is a small date difference between published PSI and CIB transition notices.
The PSI bulletin describes the 2018 edition becoming unavailable beginning December 14, 2026.
The newer CIB code-transition announcement states that the transition continues through December 14 and exclusive 2024-code testing begins December 15.
To avoid problems, candidates testing near or after the transition should use the 2024 IBC and verify their specific examination instructions with PSI.
Oklahoma amendments must also be reviewed.
The current PSI technical exam reference list includes multiple NRCA manuals.
They include:
The older 2021 NRCA Steep-Slope Manual was removed from the permitted reference list effective March 15, 2026.
Contractor Exam Preps sells the 2025 NRCA Roofing Manual: Steep-Slope Roof Systems.
Other related roofing books and collections are available through the store.
For exam-day use, always compare the exact book edition against the PSI bulletin.
Yes.
The Commercial Roofing Contractor Endorsement technical exam is open book.
Approved references may be highlighted and underlined before testing.
Permanent indexing tabs are permitted.
Temporary tabs, loose papers, and handwritten notes are not permitted.
Candidates may not write in their reference books during the examination.
A silent, nonprinting, nonprogrammable calculator is allowed.
Knowing how to locate information quickly is an important preparation skill.
The Oklahoma Construction Industries Board requires general liability insurance for roofing registration.
For residential-only roofing registration, the minimum general liability coverage is $500,000.
For commercial roofing work, the minimum is $1,000,000.
The certificate of insurance must meet CIB requirements.
Applicants must also provide required proof of workers' compensation coverage or an applicable exemption.
Always confirm the specific documentation with the Board.
Yes.
Oklahoma roofing contractor registrations and commercial endorsements must be renewed annually.
Contractors must maintain the registration and required endorsement in good standing.
Insurance and other compliance requirements continue after registration.
New continuing education rules are also becoming important.
Oklahoma adopted major residential roofing changes through House Bill 1628 and later legislation.
The residential endorsement transition begins January 1, 2027.
Beginning January 1, 2028, a Residential Roofing Endorsement becomes required for residential roofing work.
Contractors registered and in good standing by January 1, 2027 may qualify for a grandfathering pathway.
That pathway requires an application, applicable fees, and either approved grandfathering education or successful examination.
Commercial endorsement holders who meet the transition requirements have a separate path to obtain the residential endorsement during the transition period.
After January 1, 2028, contractors who want a new residential endorsement generally must satisfy the examination requirements.
Contractors should monitor the official CIB residential endorsement update.
Oklahoma also changed commercial roofing continuing education requirements.
Beginning January 1, 2027, qualifying parties renewing a Commercial Roofing Endorsement must complete four hours of approved continuing education annually.
The new Residential Roofing Endorsement also has an annual four-hour continuing education requirement when applicable.
Contractors holding both endorsements may need eight approved hours annually.
Some older CIB pages still describe a four-hour requirement every 36 months.
The newer 2026 CIB legislative announcement explains the annual requirement beginning in 2027.
The Roofing Business and Law examination contains eight official categories.
These categories total 50 questions.
Study estimating, bids, financial records, contracts, insurance, project oversight, and state rules.
Review Oklahoma roofing registration laws and related regulations.
The approved reference list includes the NASCLA Contractors Guide to Business, Law and Project Management, Basic 14th Edition.
Contractor Exam Preps offers several verified products related to Oklahoma commercial roofing preparation.
The NRCA Steep-Slope Roofing Manual, 2025 is directly listed in the Oklahoma technical exam references.
The store also sells Roofing Construction and Estimating, a useful supplemental book for roofing quantities, materials, and project planning.
That estimating book is not on Oklahoma's current commercial roofing technical exam reference list and should be treated as a study resource rather than an approved exam-room book.
The NASCLA Basic 14th Edition with Tabs supports Oklahoma Roofing Business and Law preparation.
Related roofing manuals and packages can also be explored through Contractor Exam Preps.
Some packages are designed for other states, so their contents should not be assumed to match Oklahoma's exam-room reference list.
Start with the official PSI examination outline.
Review all six technical subjects.
Spend extra time on low-slope roofing, architectural metal roofing, flashing, and reroofing.
Study roof moisture and energy control.
Practice OSHA safety questions.
Learn the approved NRCA and SMACNA reference books.
Review the 2024 IBC for upcoming examinations.
Prepare for Roofing Business and Law separately.
Complete timed practice examinations using the actual limits.
Good preparation should help you identify the topic, find the correct reference, and answer the question without wasting valuable test time.
Important Oklahoma Roofing Contractor Update: The official PSI Commercial Roofing Contractor Endorsement trade exam contains 50 questions, allows 150 minutes, and requires 70% passing, equal to 35 correct answers. Roofing Business and Law is a separate 50-question, 120-minute examination with the same 70% passing requirement. During Oklahoma's 2026 building code transition, 2018 and 2024 International Building Code editions are listed as options. The PSI bulletin and CIB announcement differ by one day on the final transition date, so candidates testing in mid-December should confirm with PSI and prepare using the 2024 IBC. Oklahoma is also introducing a Residential Roofing Endorsement with a 2027 transition and a January 1, 2028 requirement. Beginning January 2027, commercial roofing endorsement renewal requires four hours of approved continuing education annually.
An Oklahoma roofing contractor is a registered individual or business engaged in roofing services under the state's Roofing Contractor Registration Act.

The Commercial Roofing Contractor Endorsement examination can be challenging because it covers several different roofing systems and technical standards.
The test contains 50 questions.
Candidates have 150 minutes.
That gives about three minutes per question.
Low Slope Roofing is the largest subject.
Contractors experienced mainly in residential shingle roofing may need extra study time for commercial membrane systems.
Those who specialize in membranes may need more practice with architectural metal roofing and flashing.
Repairs, reroofing, insulation, moisture control, and OSHA safety also deserve attention.
The examination is open book, but the approved references cover many technical topics.
Practice makes it easier to find the right information quickly.
The separate Business and Law examination adds another set of topics, including contracts, finance, and registration rules.
A good study schedule should prepare you for both examinations.
Contractor Exam Preps offers related roofing manuals, estimating resources, and Business and Law study books.

Preparing for the Oklahoma Roofing Contractor examination is an important goal for roofing professionals who want to expand their business opportunities and perform roofing work in compliance with state requirements.
Roofing contractors protect buildings from rain, wind, hail, snow, and other weather conditions.
The work includes roof installation, replacement, repair, maintenance, waterproofing, and related construction activities.
A properly installed roofing system includes several important components.
These may include the roof deck, insulation, underlayment, membrane, flashing, fasteners, drainage, and weather barriers.
Each component performs a specific job.
When one component fails, the entire building may be affected.
That is why technical roofing knowledge matters.
Oklahoma regulates roofing contractors through the Construction Industries Board.
