- LA-RRC is the trade exam for subclassification 9.2, Residential Roofing, under Louisiana's Residential Construction license category.
- PSI administers a 50-question, open-reference, computer-delivered exam with a 2-hour limit and 70% passing score.
- The exam fee is $125; PSI may add up to 10 unscored experimental questions you won't be able to identify.
- Act 422 (effective Jan. 1, 2026) requires this trade exam for residential roofing projects valued at $7,500 or more.
What Is the LA-RRC, Exactly?
LA-RRC stands for the Louisiana Residential Roofing Contractor Exam, the trade examination the Louisiana State Licensing Board for Contractors (LSLBC) requires for anyone seeking the Residential Roofing subclassification - listed on the board's schedule as subclassification 9.2 under the broader Residential Construction license category. This is not a generic "roofing certificate" you can buy online; it's a state-mandated, third-party-administered test tied directly to your legal ability to contract residential roofing work in Louisiana.
The exam itself is developed and delivered by PSI, a well-known testing vendor used by licensing boards across the country. If you've ever sat for another PSI-administered trade exam, the software and testing-center environment will feel familiar, but the content is unique to Louisiana's residential roofing statutes, building code adoption, and safety standards.
For a broader breakdown of what the credential involves once you have it, see our companion piece on LA-RRC Certification, and if you're still untangling the acronym itself, our LA-RRC Meaning article covers the terminology in more depth.
Who Needs the LA-RRC and Why It Matters Now
Roofing contractors, remodeling companies that self-perform roof work, and tradespeople looking to legally bid and contract residential roofing jobs in Louisiana are the primary audience for this exam. If you supervise crews, pull permits, or sign contracts for residential roof replacements and repairs, passing this exam is the gateway to doing that work above a certain dollar threshold.
That threshold is changing soon. Under Act 422, effective January 1, 2026, any residential roofing project valued at $7,500 or more requires the contractor to hold the Residential Roofing or Residential Construction classification - and that contractor must have passed the trade examination. Work below that dollar amount may fall outside the licensing requirement, but once a job crosses $7,500, an unlicensed contractor is operating outside the law.
Key Takeaway
If your average roofing job is a full tear-off and replacement rather than a small patch, you are almost certainly working above the $7,500 threshold and need this license starting January 1, 2026.
There's also a related insurance change worth knowing: Act 757 raises the residential liability-insurance minimum to $500,000, effective August 1, 2026. That's a separate requirement from the exam itself, but it's part of the same regulatory tightening around residential roofing in Louisiana, and contractors planning their licensing timeline should account for both dates. We break down the full cost picture - exam fee, insurance, and other line items - in LA-RRC Certification Cost 2026: Complete Pricing Breakdown.

Exam Format, Fee, and Registration Mechanics
The LA-RRC is a computer-delivered, multiple-choice exam. Here's what candidates can expect on test day:
- 50 scored questions, with PSI reserving the right to insert 1-10 additional unscored experimental questions that are indistinguishable from the scored ones.
- 2-hour time limit for the full exam.
- 70% passing score required on the scored portion.
- $125 examination fee, paid as part of the PSI registration process.
- Open-reference format - you're allowed to bring approved printed reference materials into the testing room, which changes how you should prepare (more on that below).
Because unscored experimental questions are mixed in without identification, don't waste time trying to guess which questions "count." Treat every question on the screen as if it's scored, answer to the best of your ability, and move on. For a deeper dive into exactly what the 70% threshold means in terms of raw questions answered correctly, read LA-RRC Passing Score 2026: Exactly What You Need to Pass.
The Five Domains You'll Be Tested On
The LA-RRC draws its 50 scored questions from five content domains. Understanding how these domains are weighted - and which one dominates the exam - is the single most useful thing you can do before opening a study guide.
Domain 1: Materials
Covers shingles, underlayment, flashing, fasteners, and the properties of different roofing materials used in Louisiana's climate.
- Material compatibility and manufacturer specifications
- Climate-driven material selection for humidity and wind exposure
Domain 2: Installation of Roof Coverings
This is the largest domain on the exam, and candidates should expect it to carry the most questions of any content area.
- Steep-slope installation sequencing and fastening patterns
- Flashing details at penetrations, valleys, and transitions
- Manufacturer and code-based installation tolerances
Domain 3: Roof Drainage
Focuses on how water is directed off and away from a residential roof system.
- Gutter, downspout, and slope requirements
- Preventing ponding and moisture intrusion
Domain 4: Roofing Structures
Tests understanding of the structural components a roofing contractor must work with and around.
- Decking, sheathing, and framing basics relevant to roofing
- Load and ventilation considerations tied to structure
Domain 5: Safety
Covers jobsite safety practices tied to OSHA standards for residential roofing work.
- Fall protection requirements
- Ladder, scaffold, and general jobsite hazard awareness
Since Installation of Roof Coverings is the heaviest-weighted domain, it deserves proportionally more study hours than the other four combined with average effort. For a question-by-question breakdown of how each domain is likely to show up on the actual exam, see LA-RRC Exam Domains 2026: Complete Guide to All 5 Content Areas.
Approved References and What "Open-Reference" Really Means
Unlike a closed-book licensing exam where you memorize everything cold, the LA-RRC allows candidates to bring specific approved reference materials into the testing session. The approved list includes:
- The 2021 International Building Code
- OSHA 29 CFR Part 1926 (construction safety standards)
- Roofing Construction and Estimating by Daniel Atcheson
- The NRCA Roofing Manual: Steep-Slope Roof Systems
You're permitted to highlight, annotate, index, and permanently tab your bound copies of these references before the exam. This is a significant advantage if you use it well - but there are two hard rules to know ahead of time: loose pages are prohibited, and no writing of any kind is allowed during the actual testing session. That means your prep work has to happen entirely before you walk into the test center; you can't build an index or add notes on the fly.
The smart approach is to build your tabbing system around the domain structure - a section of tabs for Materials, a section for Installation of Roof Coverings, and so on - so you can jump directly to the right part of the right book when a question stumps you. Candidates who assess just how difficult this balance is between memorization and reference use should read How Hard Is the LA-RRC Exam? Complete Difficulty Guide 2026.
How to Approach Preparation
Because the LA-RRC blends code knowledge, installation technique, and safety regulation into a single 50-question test, effective preparation is less about generic test-taking tricks and more about mapping your existing field experience to how the exam actually asks questions.
Installation of Roof Coverings
- Review steep-slope installation sequencing and flashing details since this domain carries the most weight
- Tab your NRCA Roofing Manual and Atcheson text by installation topic
Materials and Roof Drainage
- Study material specifications and compatibility rules
- Work through drainage, gutter, and slope requirements
Roofing Structures and Safety
- Review structural decking and framing basics as they relate to roofing
- Study OSHA 29 CFR Part 1926 fall protection and jobsite safety provisions
Timed Practice and Reference Tabbing
- Take full-length timed practice sessions mimicking the 2-hour, 50-question format
- Finalize permanent tabs across all four approved references
This kind of sequencing works because it front-loads the domain that carries the most questions, then layers in the smaller domains before finishing with timed practice under real exam conditions.

And if you want a fast, single-page review of must-know facts before test day, bookmark the LA-RRC Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Running full practice sessions on our practice test platform is one of the most direct ways to get comfortable with the pacing and question style before you sit for the real exam at a PSI center.
After You Pass: What the LA-RRC Unlocks
Passing the LA-RRC is one part of qualifying for the Residential Roofing subclassification through LSLBC - it doesn't replace other licensing requirements like business entity registration or the insurance minimums discussed above, but it's the trade competency piece the board specifically requires. Once Act 422 takes effect on January 1, 2026, this exam becomes the dividing line between contractors who can legally bid larger residential roofing jobs and those who can't.
| Detail | Specification |
|---|---|
| Administering body | PSI (for LSLBC) |
| License subclassification | 9.2 - Residential Roofing (Residential Construction category) |
| Scored questions | 50 |
| Time limit | 2 hours |
| Passing score | 70% |
| Exam fee | $125 |
| Format | Computer-delivered, open-reference, multiple-choice |
Roofing companies, general contractors adding a roofing division, and independent tradespeople all have reasons to pursue this license as the $7,500 threshold reshapes who can legally sign residential roofing contracts. If you're weighing whether the investment of time and the $125 fee makes sense for your career path, our analysis in Is the LA-RRC Certification Worth It? Complete ROI Analysis 2026 lays out the considerations, and LA-RRC Salary Guide 2026: Complete Earnings Analysis looks at earning potential tied to holding this license.

Frequently Asked Questions
LA-RRC stands for the Louisiana Residential Roofing Contractor Exam, the PSI-administered trade exam tied to subclassification 9.2 under Louisiana's Residential Construction license category. For more on the terminology, see What Does LA-RRC Stand For?
The exam has 50 scored questions with a 2-hour time limit. PSI may include up to 10 additional unscored experimental questions that look identical to scored ones.
Yes, but only the four approved references: the 2021 International Building Code, OSHA 29 CFR Part 1926, Roofing Construction and Estimating by Daniel Atcheson, and the NRCA Roofing Manual: Steep-Slope Roof Systems. Bound copies can be highlighted, annotated, and tabbed beforehand, but loose pages aren't allowed and you cannot write during the test.
Installation of Roof Coverings is the largest domain on the LA-RRC, so it should get the largest share of your preparation time relative to Materials, Roof Drainage, Roofing Structures, and Safety.
Under Act 422, effective January 1, 2026, residential roofing projects valued at $7,500 or more require the Residential Roofing or Residential Construction classification, and the contractor must have passed this trade exam. Act 757 separately raises the residential liability-insurance minimum to $500,000 effective August 1, 2026.
