- Residential Roofing is subclassification 9.2, tested by PSI with a $125 exam fee.
- You need 50 scored questions correct at 70% within a 2-hour window to pass.
- Act 422 requires the trade exam for residential roofing projects worth $7,500 or more starting January 1, 2026.
- Act 757 raises required liability insurance to $500,000 effective August 1, 2026.
What the LA-RRC Actually Requires
The Louisiana Residential Roofing Contractor Exam (LA-RRC) is not a generic industry certificate - it is the trade examination the Louisiana State Licensing Board for Contractors requires for anyone seeking to operate under subclassification 9.2, Residential Roofing, within the Residential Construction license category. Understanding "requirements" for the LA-RRC means understanding three separate things at once: who is legally required to hold this credential, what PSI (the third-party testing administrator) requires of you on exam day, and what the state requires afterward to keep the license active.
This guide walks through each layer so you know exactly what to prepare, when to register, and what changes in 2026 affect your qualification path. If you're still unclear on the basics of the credential itself, start with What Is LA-RRC? or LA-RRC Certification before diving into the specifics below.
Subclassification 9.2 and Act 422
Residential Roofing sits under subclassification 9.2 of Residential Construction. This matters because it determines which projects legally require you to hold the credential and pass the exam. Under Act 422, effective January 1, 2026, any residential roofing project valued at $7,500 or more requires the contractor to hold either the Residential Roofing or Residential Construction classification - and to have passed the trade examination tied to that classification.
If you've been operating below that threshold or subcontracting under someone else's license, 2026 is the year to reassess. Projects that once flew under the radar on cost will now need a licensed, exam-qualified contractor attached to the contract.
Eligibility and Prerequisites
The path to sitting for the LA-RRC runs through the Louisiana State Licensing Board for Contractors' application process. Before PSI will schedule you for the trade exam, your application and supporting documentation must be accepted by the Board. Once approved, you're cleared to register for the computer-delivered exam administered by PSI.
There isn't a separate "LA-RRC prerequisite course" you must complete before testing - the requirement is built around the Board's application review and passing the trade exam itself. That makes exam readiness the real gatekeeper. A candidate who understands roofing materials, installation sequencing, drainage systems, structural framing, and jobsite safety at the level tested by PSI is functionally prepared to qualify, regardless of how many years they've spent in the field.
Key Takeaway
Your real prerequisite isn't paperwork - it's mastering the five tested domains well enough to clear 70% inside a 2-hour window. Treat the exam content as the actual eligibility bar.
Registration, Fees, and Scheduling
Once your application is in good standing with the Board, registering for the exam itself is straightforward:
- Testing administrator: PSI
- Exam fee: $125
- Format: Computer-delivered, open-reference, multiple-choice
- Length: 50 scored questions, plus PSI may include 1-10 unscored experimental questions mixed in without identification
- Time limit: 2 hours
- Passing score: 70%
Because unscored experimental questions are indistinguishable from scored ones, you should treat every question on screen as if it counts. For a full breakdown of exactly how the passing threshold is calculated and what it means for your margin of error, see LA-RRC Passing Score 2026: Exactly What You Need to Pass.

Exam Format and References
The LA-RRC is open-reference, which is a meaningful qualification detail: you're not required to memorize code sections verbatim, but you are required to know how to navigate your references quickly enough to find the right answer inside a strict time limit. The approved references are:
- 2021 International Building Code
- OSHA 29 CFR Part 1926
- Roofing Construction and Estimating by Daniel Atcheson
- NRCA Roofing Manual: Steep-Slope Roof Systems
Candidates may bring their own bound copies of these references, and those copies can be highlighted, annotated, indexed, and permanently tabbed before test day. What's prohibited: loose pages of any kind, and any writing during the actual testing session. In practice, this means your prep work on tabbing and indexing has to happen well in advance - you cannot improvise organization once the clock starts.
The Five Domains You Must Qualify On
PSI organizes the LA-RRC trade exam around five content domains. Qualifying for licensure in practice means demonstrating competence across all five - there's no path around any single domain.
Domain 1: Materials
Candidates must recognize roofing material types, their appropriate applications, and their performance characteristics under Louisiana's climate conditions.
- Underlayment and membrane selection
- Shingle, tile, and metal roofing distinctions
Domain 2: Installation of Roof Coverings
This is the largest domain on the exam, and it should receive the largest share of your study time. It covers correct sequencing, fastening, flashing, and coverage methods across steep-slope roofing systems.
- Proper overlap and exposure calculations
- Flashing details at penetrations, valleys, and edges
Domain 3: Roof Drainage
Questions in this domain test understanding of water management systems that keep roofing assemblies performing over time.
- Gutter and downspout sizing and placement
- Slope and drainage path planning
Domain 4: Roofing Structures
This domain tests knowledge of the structural elements a roofing contractor must work with and around, including load paths and framing basics relevant to residential roofing.
- Decking and sheathing requirements
- Structural compatibility with roofing loads
Domain 5: Safety
Safety questions draw directly from OSHA 29 CFR Part 1926 and test practical jobsite hazard awareness for roofing work specifically.
- Fall protection requirements
- Ladder and scaffold safety on residential jobsites
Because Installation of Roof Coverings carries the most weight, your study plan should reflect that proportionally - not spend equal time on all five domains. For a deeper walkthrough of each domain's subtopics and how questions are typically framed, see LA-RRC Exam Domains 2026: Complete Guide to All 5 Content Areas.
Insurance and Post-Exam Requirements
Passing the trade exam is a major milestone, but qualifying to actively contract residential roofing work in Louisiana also depends on meeting insurance requirements set by the Board. Act 757 raises the residential liability-insurance minimum to $500,000, effective August 1, 2026. Anyone planning to hold themselves out as a licensed residential roofing contractor after that date needs a policy that meets the new minimum - not the older, lower threshold.

Building a Qualification Timeline
Since eligibility for the LA-RRC hinges on exam readiness rather than a lengthy coursework requirement, most candidates can move from application to passing score in a matter of weeks - provided their study time is allocated according to domain weight rather than spread evenly.
Materials and Reference Setup
- Tab and index your 2021 IBC, OSHA 1926, Atcheson text, and NRCA manual
- Study Domain 1 material types and applications
Installation of Roof Coverings
- Focus the majority of study hours here since it's the largest domain
- Drill flashing, fastening, and sequencing scenarios
Drainage and Structures
- Cover Domain 3 drainage systems and Domain 4 structural basics together
- Practice locating relevant code sections quickly in your tabbed references
Safety and Timed Practice
- Review OSHA 1926 fall protection and ladder safety rules for Domain 5
- Run full 50-question, 2-hour timed practice sessions
This is a domain-weighted approach, not a generic study calendar - it exists because Installation of Roof Coverings is explicitly the largest domain and deserves the largest allocation of preparation time.

Frequently Asked Questions
Qualification runs through the Louisiana State Licensing Board for Contractors' application process rather than a fixed experience formula published as an exam fact. What is fixed is the exam content itself - you need working knowledge across Materials, Installation of Roof Coverings, Roof Drainage, Roofing Structures, and Safety strong enough to clear 70%.
Yes. Bound copies of the approved references - the 2021 IBC, OSHA 29 CFR Part 1926, Roofing Construction and Estimating, and the NRCA Roofing Manual: Steep-Slope Roof Systems - may be highlighted, annotated, indexed, and tabbed beforehand. Loose pages aren't allowed, and no writing is permitted during the session.
Residential roofing projects valued at $7,500 or more will require the contractor to hold the Residential Roofing or Residential Construction classification and to have passed the trade exam. This significantly expands which projects legally require a licensed roofer.
Act 757 raises the residential liability-insurance minimum to $500,000, effective August 1, 2026. Contractors need to confirm their policy meets this higher minimum by that date regardless of when they passed the trade exam.
Installation of Roof Coverings is the largest domain on the exam, so it should receive the largest share of your preparation time relative to Materials, Roof Drainage, Roofing Structures, and Safety.
