Important 2026 Oklahoma code transition: from September 14 through December 14, 2026, candidates taking the affected Commercial Roofing Contractor Endorsement exam may use the previous or newly adopted building-code version. The current PSI bulletin lists the 2018 or 2024 International Building Code with Oklahoma revisions during this transition. Beginning December 15, 2026, the 2018 IBC is no longer allowed.
What Is Oklahoma Roofing Contractor Exam Prep?
Oklahoma Roofing Contractor Exam Prep helps roofing professionals prepare for the technical and business requirements connected to Oklahoma roofing registration and the Commercial Roofing Contractor Endorsement.
The statewide system begins with Roofing Contractor Registration through the Oklahoma Construction Industries Board. Contractors performing commercial roofing work need the commercial endorsement in addition to an active registration.
The Commercial Endorsement covers a broad range of work, including roofing installation, renovation, remodeling, reroofing, reconstruction, repair, maintenance, alteration, improvement, and waterproofing. Commercial roofing contractors may supervise personnel, manage roofing activities, supply materials, and solicit commercial roofing contracts.
Technical exam: 50 scored questions.
Time: 150 minutes.
Passing score: 70% or 35 correct answers.
Format: open book.
Additional exam: commercial endorsement candidates also complete Roofing Business and Law.
For structured technical preparation, the Oklahoma Roofing Contractor Commercial Endorsement Online Exam Prep Course focuses on low-slope roofing, architectural metal roofing, sheet-metal flashing, moisture and energy control, repairs, reroofing, roofing knowledge, OSHA safety, and reference navigation.

Oklahoma Roofing Contractor Exam Prep Breakdown
The current Commercial Roofing Contractor Endorsement examination contains six scored categories. Low-Slope Roofing is the largest with 15 questions, which makes it 30 percent of the technical examination.
Architectural Metal Roofing Systems and Sheet Metal Flashing contains 9 questions. Repairs and Reroofing contains 8. Safety contains 7. Moisture and Energy Control contains 6, while General Roofing Knowledge contains 5.
This is a technical roofing exam, not a quiz about whether shingles belong on the roof instead of in the truck. You need to understand roof systems, materials, flashing, drainage, moisture, reroofing, safety, code provisions, and how to navigate a large reference library efficiently.

How to Study for the Oklahoma Roofing Contractor Exam
Build your study plan around the six PSI categories. The exam tells you where the points live. Your study calendar should listen.
Low-slope roofing: give this the most time because it represents 15 of the 50 scored questions.
Metal and flashing: practice architectural metal systems, sheet-metal details, joints, edges, penetrations, and transitions.
Open-book strategy: practice identifying which reference contains the answer before you begin searching.
Roofing Systems, Details, and Reference Strategy
Commercial roofing questions often combine practical roofing knowledge with technical reference details. A strong approach is to identify the roofing system first, choose the correct book, locate the relevant detail, and then apply that information to the question.

- Moisture Control: review condensation, vapor movement, air leakage, insulation, and energy-control concepts
- Repairs and Reroofing: study existing roof evaluation, removal, overlays, substrate conditions, repairs, and reroofing code rules
- Safety: focus on fall protection, ladders, scaffolds, PPE, material handling, and construction safety requirements
- Code Navigation: practice switching quickly between the IBC, NRCA manuals, SMACNA, and OSHA references

Oklahoma Roofing Registration vs Commercial Endorsement
Oklahoma does not treat every roofing contractor exactly the same. The base requirement is Roofing Contractor Registration through the Construction Industries Board.
For commercial roofing work, an active registration alone is not enough. A contractor also needs the Commercial Roofing Contractor Endorsement unless a specific statutory exemption applies.
Commercial endorsement candidates must pass the required examination process, maintain commercial-level liability insurance, satisfy workers' compensation requirements, and keep the registration and endorsement current.
Oklahoma is also changing the residential side. A new Residential Roofing Endorsement transition begins January 1, 2027. The state has established a grandfathering window through January 1, 2028, after which the Residential Roofing Endorsement becomes required for residential roofing work under the new framework.
Oklahoma Roofing Credential Comparison
Choose the path that matches the roofing work you actually plan to perform.
| Path | Main Purpose | Important Difference |
|---|---|---|
| Roofing Contractor Registration | Base statewide registration to offer or perform roofing services | Required before a Commercial Endorsement can be approved |
| Residential Roofing | Residential roofing work under the current registration framework | New Residential Endorsement requirements are transitioning in beginning in 2027 |
| Commercial Roofing Endorsement | Authority to perform commercial roofing work | Requires registration in good standing plus technical and Business and Law examination requirements |
| Roofing Business & Law | Contractor business, financial, legal, labor, and licensing knowledge | Separate 50-question exam from the technical roofing test |
| Residential Roofing Endorsement | Future residential endorsement under the new Oklahoma framework | Transition and grandfathering begin January 1, 2027; endorsement becomes required beginning January 1, 2028 |

How Hard Is the Oklahoma Roofing Contractor Exam?
The technical exam can be challenging because candidates must understand several different commercial roofing systems while working with a large open-book reference library.
You have 150 minutes for 50 scored questions. That works out to about three minutes per question. Three minutes sounds comfortable until you have seven books on the desk and cannot remember which one contains the flashing detail you need.
The best preparation combines roofing knowledge with reference navigation. If you already know that a membrane question probably lives in the NRCA Membrane Roofing Systems manual, you save time before the search even begins.
Low-Slope Roofing deserves the most attention because it contains 15 questions. But do not ignore safety. Seven OSHA-focused questions can turn into seven very expensive guesses if your fall-protection knowledge is rusty.
