What the LA-RRC Exam Actually Tests
The Louisiana Residential Roofing Contractor Exam, administered through PSI on behalf of the Louisiana State Licensing Board for Contractors, is the trade examination for subclassification 9.2 (Residential Roofing) under the Residential Construction license category. It is not a generic contractor's business-and-law test - it is a hands-on, materials-and-methods exam built specifically around how residential roofs are specified, installed, drained, framed, and safely worked on in Louisiana's climate.
The format is computer-delivered and open-reference, with 50 scored multiple-choice questions and a 2-hour time limit. PSI may also insert up to 10 unscored experimental questions that look identical to the scored ones, so you cannot game the test by trying to identify which questions "count." You need a 70% passing score, which means you have to answer roughly 35 of the 50 scored questions correctly - but since you can't tell which questions are experimental, the safest strategy is to treat every question as if it counts. For a deeper breakdown of exactly how that score is calculated, see our LA-RRC Passing Score guide.
Registration, Fees, and Exam-Day Mechanics
Before you can sit for the exam, you'll need to satisfy the Board's eligibility requirements and submit your application - we cover the full checklist in our LA-RRC Requirements guide. Once approved, you schedule your test through PSI. The exam fee is $125, and because this is a computer-based test delivered at PSI testing centers, scheduling availability varies by location and demand rather than following fixed annual dates - our LA-RRC Exam Dates guide walks through how to plan around that.
On test day, you'll check in, secure your belongings, and bring only your approved references into the testing room. No scratch paper writing beyond what the testing center provides, and critically: no writing inside your reference books during the session. All highlighting, indexing, and tabbing has to happen beforehand. If you show up with a fresh, unmarked copy of the IBC and expect to flip through it cold in two hours, you will run out of time long before you run out of questions.
Key Takeaway
Treat your reference books as study tools during prep, not just exam-day crutches. If you're flipping to a tab for basic terminology you should already know, you're spending time you don't have.
The Five Domains, Ranked by What Matters Most
The exam blueprint covers five domains: Materials, Installation of Roof Coverings, Roof Drainage, Roofing Structures, and Safety. Installation of Roof Coverings is explicitly the largest domain, which means it deserves the largest share of your study hours. For a question-by-question breakdown of what each domain actually covers, our LA-RRC Exam Domains guide goes deeper than the summary below.
Domain 1: Materials
Candidates need to identify and compare residential roofing materials - asphalt shingles, tile, metal panels, wood shakes, and underlayment types - along with their appropriate applications, limitations, and code-driven compatibility rules.
- Underlayment selection for different slope and climate conditions
- Fastener types and corrosion resistance appropriate to material choice
Domain 2: Installation of Roof Coverings
As the largest domain, this is where the exam concentrates its weight. Expect detailed questions on sequencing, flashing details, nailing patterns, exposure and overlap requirements, and manufacturer installation standards referenced in the NRCA Roofing Manual: Steep-Slope Roof Systems.
- Step, valley, and chimney flashing methods
- Starter course and ridge cap installation sequencing
Domain 3: Roof Drainage
This domain covers gutter systems, downspout sizing, scupper placement, and how water is directed off a residential roof without pooling or backing up under coverings.
- Gutter slope and downspout capacity basics
- Drainage detailing at valleys and low-slope transitions
Domain 4: Roofing Structures
Expect questions on framing components - rafters, trusses, decking, and sheathing - and how structural elements interact with the roof covering system above them.
- Decking and sheathing requirements tied to the 2021 International Building Code
- Structural load and ventilation interaction points
Domain 5: Safety
Safety questions draw directly from OSHA 29 CFR Part 1926, focusing on fall protection, ladder use, and jobsite hazard awareness specific to steep-slope residential work.
- Fall protection requirements for residential roofing
- Ladder setup and jobsite hazard identification
If you're trying to gauge how tough this actually is compared to what you've heard about other trade exams, our difficulty breakdown and pass rate analysis give context without relying on made-up numbers.
Approved References and How to Tab Them Legally
Four references are approved for the exam: 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. You're allowed to bring your own bound copies, and you can highlight, annotate, index, and permanently tab them before test day. What you cannot do is bring loose pages, printed excerpts, or write anything new during the exam itself.
| Reference | Primary Use During Exam |
|---|---|
| 2021 International Building Code | Code-based questions on structures, decking, and general compliance |
| OSHA 29 CFR Part 1926 | Safety domain - fall protection, ladders, jobsite hazards |
| Roofing Construction and Estimating (Atcheson) | Materials, installation sequencing, general trade practice |
| NRCA Roofing Manual: Steep-Slope Roof Systems | Installation of Roof Coverings - flashing, exposure, manufacturer standards |
Building a Study Timeline That Matches the Exam
Because Installation of Roof Coverings carries the most weight and the exam only gives you two hours to move through 50 questions, your prep schedule should mirror that imbalance rather than splitting time evenly across all five domains. A four-week runway works well for most candidates who already have field experience.
Materials & Roofing Structures
- Review material types, fastener compatibility, and underlayment selection
- Study decking, sheathing, and framing basics from the IBC
Installation of Roof Coverings (heaviest focus)
- Work through flashing details and installation sequencing in the NRCA manual
- Practice identifying correct nailing patterns and exposure requirements
Roof Drainage & Safety
- Map out gutter and downspout sizing scenarios
- Review OSHA fall protection and ladder safety rules
Full-Length Practice & Reference Tabbing
- Take timed practice sessions under the 2-hour limit
- Finalize permanent tabs across all four approved references
Running full-length, timed practice questions on our practice test platform before exam day is the single best way to know whether your tabbing system and pacing actually hold up under the real 2-hour constraint.
Why 2026 Changes the Stakes for New Applicants
Two legislative changes make passing this exam more consequential in 2026 than in prior years. Under Act 422, effective January 1, 2026, any residential roofing project valued at $7,500 or more requires the Residential Roofing or Residential Construction classification - and to hold that classification as a roofing contractor, you must pass this trade exam. That threshold is low enough that it captures the majority of full roof replacement jobs, not just large commercial-scale work, which means unlicensed roofers who used to operate under the radar on mid-sized jobs no longer have that option.
Separately, Act 757 raises the residential liability-insurance minimum to $500,000, effective August 1, 2026. That's a meaningful jump in the cost of doing business legally, and it reinforces the same trend: Louisiana is tightening enforcement around who is allowed to perform residential roofing work and what financial backing they need to carry while doing it.
Key Takeaway
If you're planning to bid residential roofing jobs at or above $7,500 after January 1, 2026, passing this exam isn't optional paperwork - it's the legal gate to that revenue.

Common Mistakes That Sink First-Time Candidates
- Under-tabbing the NRCA manual. Since Installation of Roof Coverings is the largest domain, a thin tab system there costs you more time than anywhere else.
- Assuming "open-reference" means casual prep. Candidates who haven't internalized core terminology still burn too much time flipping pages and run out of clock before finishing all 50 questions.
- Bringing unauthorized materials. Loose printouts or personal notes get confiscated at check-in - only bound, tabbed books are allowed in the room.
- Ignoring Safety questions. OSHA-based questions feel straightforward in review but are easy to miss under time pressure if you haven't actually read Part 1926's residential-specific provisions.
- Skipping timed practice. Knowing the material and finishing 50 questions in 2 hours are two different skills - build pacing practice into your last week using resources like the LA-RRC Cheat Sheet alongside full simulated tests on our practice exam site.
