OK-ROOF Requirements Overview
The Oklahoma Roofing Contractor Commercial Endorsement Examination (OK-ROOF) is issued by the Oklahoma Construction Industries Board, with PSI handling exam delivery and scoring. Before you can sit for the exam, though, you have to clear a set of administrative and legal hurdles that have nothing to do with roofing knowledge itself: age, registration status, business formation, and insurance documentation. Many candidates focus entirely on exam content and get blindsided by these prerequisite steps late in the process.
This guide breaks down every requirement in the order you'll actually encounter it, from your first registration filing through the exam day rules and into renewal obligations that start piling up after you're certified. If you haven't yet reviewed what the credential actually is, start with What Is OK-ROOF? or OK-ROOF Certification for the broader context before working through the eligibility checklist below.
Baseline Eligibility Rules
The foundational requirements for the OK-ROOF pathway are straightforward but non-negotiable:
- Minimum age of 18. No exceptions are made for younger applicants, even those working under a licensed roofer.
- An Oklahoma roofing registration in good standing. The commercial endorsement is layered on top of this base registration, not a replacement for it.
- An actively engaged qualifying party. This individual must be genuinely involved in daily operations, not simply listed on paperwork.
These rules exist because the commercial endorsement authorizes work on larger, higher-liability roofing projects than a base registration alone typically covers. The state wants confirmation that a real, accountable person with roofing knowledge is steering the business before commercial-scale work begins.
The Qualifying Party Requirement
The qualifying party concept trips up a lot of first-time applicants, especially those forming a new roofing company rather than joining an established one. The qualifying party is the person whose competency effectively backs the business's roofing registration and commercial endorsement. Oklahoma requires this person to be "actively engaged" in the business - a phrase that rules out silent partners or figurehead designations.
In practice, this means:
- The qualifying party is usually the one who sits for and passes the technical exam and the Business and Law exam.
- If the qualifying party leaves the business, the commercial endorsement's standing can be affected until a new qualifying party is designated and verified.
- Small companies and sole proprietors often serve as their own qualifying party, which simplifies this step considerably.
Key Takeaway
If you're forming a new roofing business specifically to pursue the commercial endorsement, confirm who your qualifying party will be before you file any paperwork - this decision shapes who needs to test and when.
Insurance, Business Registration & Bonding
Beyond individual eligibility, Oklahoma requires the business entity itself to meet formation and coverage standards before the commercial endorsement is granted:
- Secretary of State registration. The roofing business must be formally registered as a legal entity in Oklahoma.
- $1 million in general liability coverage. This documentation must be current and on file, reflecting the scale of commercial roofing risk.
- Workers' compensation coverage. Required alongside general liability for any business employing roofing crews.
These aren't exam topics - they're gatekeeping requirements verified through paperwork submitted to the Construction Industries Board. Gathering insurance certificates and business filings early avoids a bottleneck after you've already invested time studying for the technical exam.
Two Exams: Technical and Business and Law
A detail that surprises many applicants: qualifying for the commercial endorsement requires passing two separate PSI examinations, not one.
- Commercial Roofing Technical Examination. The $92 exam covering roofing systems, materials, and methods across six domains.
- Roofing Business and Law Examination. A separate 50-question exam focused on Oklahoma-specific business practices, contracts, and regulatory obligations rather than roofing technique.
This article and most resources on this site - including the OK-ROOF Study Guide 2026: How to Pass on Your First Attempt - focus primarily on the technical exam, since that's where roofing-specific knowledge is tested most heavily. But don't let the Business and Law exam become an afterthought; it's a distinct pass/fail requirement with its own content to review.
Exam Format, Timing & Scoring
Once your eligibility items are squared away, here's exactly what to expect from the commercial roofing technical exam itself:
| Exam Detail | Specification |
|---|---|
| Administering body | PSI, on behalf of the Oklahoma Construction Industries Board |
| Scored questions | 50 |
| Time limit | 2 hours 30 minutes |
| Passing score | 70% |
| Delivery method | Computer delivered |
| Reference policy | Open book |
| Calculator policy | Silent, nonprinting, nonprogrammable only |
| Exam fee | $92 |
| Unscored items | Up to 10 experimental questions, time excluded from the limit |
The open-book format is a significant advantage, but it's also a trap for underprepared candidates: 50 questions in 2 hours 30 minutes doesn't leave much room to flip through references for every item. You need to know the material well enough to look things up quickly and confidently, not to learn it fresh during the exam. The current PSI references center on the 2025 NRCA Steep Slope manual, so make sure whatever materials you bring to the test center match what's actually referenced.

What the Technical Exam Actually Covers
Meeting the paperwork requirements gets you to the testing center, but passing the technical exam requires mastering six defined content domains. Understanding domain weight and scope is arguably the most important part of preparing efficiently.
Domain 2: Low Slope Roofing (Largest Domain)
This is the single largest content area on the exam, covering membrane systems, drainage, insulation layering, and installation sequencing specific to low-slope commercial applications.
- Prioritize this domain first in your study schedule given its weight
- Expect scenario-based questions about system selection and installation order
Domain 1: General Roofing Knowledge
Foundational terminology, materials science, and roofing principles that underpin questions across every other domain.
- Treat this as prerequisite knowledge, not a standalone silo
Domain 3: Architectural Metal Roofing Systems and Sheet Metal Flashing
Covers metal panel systems, seaming methods, and flashing details at penetrations, valleys, and transitions.
- Flashing detail questions often test sequencing and water-shedding logic
Domain 4: Moisture and Energy Control
Vapor barriers, insulation performance, and moisture management strategies across roofing assemblies.
- Connects closely with low slope roofing content on drainage and insulation
Domain 5: Repairs and Reroofing
Assessment of existing roof conditions, tear-off decisions, and reroofing over existing systems where code permits.
- Expect questions distinguishing repair scope from full reroof scenarios
Domain 6: Safety
Jobsite safety practices specific to roofing work, fall protection, and hazard awareness on commercial projects.
- Often tested through practical, situational question phrasing
For a full walkthrough of every domain with more granular subtopics and sample question framing, see the OK-ROOF Exam Domains 2026: Complete Guide to All 6 Content Areas. Because Low Slope Roofing carries the most weight, allocating a disproportionate share of your review time there is a reasonable strategy rather than an even split across all six domains.
Fee Schedule and Renewal Requirements
Meeting the requirements for OK-ROOF isn't just about knowledge and paperwork - it comes with a defined cost structure you should budget for upfront:
- Initial registration: $75
- Initial commercial endorsement: $230
- Technical exam fee: $92 (paid to PSI)
- Annual registration renewal: $75
- Annual endorsement renewal: $100
These fees recur every year the endorsement stays active, so factor renewal costs into your long-term planning rather than treating certification as a one-time expense. A full cost breakdown, including how these figures compare across the initial application year versus ongoing years, is available in OK-ROOF Certification Cost 2026: Complete Pricing Breakdown.
The 2027 Continuing Education Rule
One requirement that hasn't taken effect yet but that every 2026 applicant should plan around: starting January 1, 2027, Oklahoma will require 4 continuing education hours annually to maintain the commercial endorsement. If you earn your endorsement in 2026, you'll need to identify and complete qualifying CE hours before your first renewal cycle after that date.
Key Takeaway
Build a habit of tracking CE opportunities now, even though the requirement doesn't start until 2027 - waiting until the deadline approaches leaves less flexibility in scheduling qualifying coursework.
Building a Requirements-Driven Prep Plan
Because OK-ROOF has both administrative prerequisites and a content-heavy exam, your preparation timeline should run two tracks simultaneously: paperwork and study. Here's a structure that keeps both moving without letting either stall the other.
Administrative Foundation
- Confirm base roofing registration status and qualifying party designation
- Begin gathering liability and workers' compensation documentation
- File or confirm Secretary of State business registration
Domain 2: Low Slope Roofing
- Deep review of membrane systems, drainage, and insulation layering
- Practice scenario questions on installation sequencing
Domains 1 and 4
- Reinforce general roofing terminology and materials knowledge
- Study moisture and energy control alongside low slope content given the overlap
Domains 3, 5, and 6
- Metal roofing systems and sheet metal flashing details
- Repair versus reroof decision-making scenarios
- Safety practices and situational judgment questions
Business and Law Prep, Final Review
- Shift focus to the separate Business and Law exam content
- Run timed practice sessions to build comfort with the 2 hour 30 minute window
- Organize your open-book references, including the 2025 NRCA Steep Slope manual
Use timed practice runs through resources like our practice test platform to simulate the actual open-book, calculator-permitted testing conditions before exam day. Repetition under realistic time pressure is what turns open-book access from a safety net into an actual speed advantage.

Frequently Asked Questions
Yes. The commercial endorsement is layered on top of an Oklahoma roofing registration in good standing - it isn't a standalone credential you can obtain independently.
Yes, the commercial roofing technical exam is open book and computer delivered, though the 2 hour 30 minute time limit means you still need strong content knowledge to move efficiently through all 50 scored questions.
Two: the commercial roofing technical examination and a separate 50-question Roofing Business and Law examination, both administered by PSI.
Applicants must document $1 million in general liability coverage plus workers' compensation coverage for the business before the endorsement is issued.
Four CE hours become an annual requirement for maintaining the commercial endorsement starting January 1, 2027, so 2026 applicants should plan ahead for their first renewal cycle after that date.
