- Steep Roofing carries the most weight on the exam at 16 of 60 scored questions, so employers assume strength there.
- The application fee is $300, with initial licensing and biennial renewal each at $600 plus Residential Recovery Fund charges.
- Required exams must be finished within six months of applying, and three failed attempts void the application.
Why the License Comes Before the Job Offer
In Nevada, "NV-C15 jobs" doesn't mean applying for a position called C-15 - it means qualifying to legally bid, contract, or supervise roofing and siding work under a license issued by the Nevada State Contractors Board. Before any of that hiring conversation happens, a candidate has to clear the trade exam administered by PSI. That single requirement filters who can operate as a licensed roofing and siding contractor in the state, which is exactly why the job market for this trade is tied so tightly to exam readiness.
If you're still mapping out what the credential covers, the NV-C15 Certification overview and the What Is NV-C15? explainer are good starting points before you think about employers or job titles.
Who Actually Hires NV-C15 Licensed Contractors
The employers and business structures looking for C-15-licensed talent in Nevada generally fall into a few categories:
- Established roofing companies expanding their supervisory bench - foremen and project leads who can be named as the qualifying individual on permits.
- Siding and exterior remodeling contractors who need someone licensed to run jobs that combine siding installation with roofing tie-ins.
- Solar installation firms that need roofing-savvy staff who also understand penetrations, flashing, and mounting on existing roof systems - a direct overlap with the Photovoltaic Systems domain.
- Insurance restoration and storm-repair crews that rely on licensed contractors to assess and repair damaged roofing substrates and steep-slope systems.
- Owner-operators who plan to start their own licensed roofing and siding business rather than work under someone else's license.
Each of these paths runs through the same gate: passing the exam and completing the Board's licensing process. Whether you're chasing a foreman title or your own contractor's license, the preparation work is identical.
The Exam Standing Between You and a Nevada Roofing License
The C-15 Roofing and Siding Contractor trade examination is computer-delivered and multiple-choice. The scored blueprint contains 60 questions, and you're given 120 minutes to work through them. PSI may quietly add between 1 and 10 unscored experimental questions mixed into the same time block - you won't know which ones are experimental, so every question deserves a real answer.
To pass, you need 45 correct answers out of the 60 scored questions, which works out to the required 75%. For the exact scoring mechanics and what that threshold means in practice, see NV-C15 Passing Score 2026: Exactly What You Need to Pass.
- Fee structure: $95 covers one examination portion; $140 covers both the trade exam and the separate Contractor Management Survey (CMS) portion together. Retakes follow this same fee schedule.
- Open-book limits: Only the listed 2018 International Building Code may be referenced during testing. NRCA manuals, OSHA materials, and other listed references are for study - not for the exam room.
- Marking rules: Highlighting, underlining, and permanent tabs applied before the exam are allowed. Handwritten notes and added papers, before or during testing, are not.
- Calculators: A silent, nonprinting, nonprogrammable calculator is permitted.

Key Takeaway
Prepare your open-book reference copy of the 2018 IBC in advance with tabs and highlights already in place - you cannot add notes once testing begins.
Domains Employers Actually Expect You to Know
Job readiness for roofing and siding supervision in Nevada maps directly onto the nine content domains PSI tests. A full breakdown of weighting and structure lives in NV-C15 Exam Domains 2026: Complete Guide to All 9 Content Areas, but here's what matters for someone thinking about actual job performance, not just passing:
Domain 3: Steep Roofing
This is the single largest domain on the exam at 16 of 60 questions - more than a quarter of the scored test. Employers assume anyone with a C-15 license is fluent in steep-slope systems, since it's the most common roofing work performed across residential Nevada construction.
- Shingle, tile, and steep-slope underlayment sequencing
- Ventilation and slope-specific fastening requirements
Domain 7: Sheet Metal and Flashing
Flashing failures are among the most common callback issues on any roofing job, which is why crews and supervisors are expected to know proper detailing at penetrations, valleys, and terminations cold.
- Step, counter, and valley flashing applications
- Metal compatibility and expansion considerations
Domain 9: Photovoltaic Systems
As solar installations on existing roofs have become routine in Nevada, this domain tests whether a licensed contractor understands how PV mounting interacts with the roof envelope - not solar electrical work itself, but the roofing side of the integration.
- Mounting penetrations and flashing around PV hardware
- Maintaining roof warranty and weatherproofing with solar additions
The remaining domains - Safety, Roofing Substrates, Roofing Repairs, Elastomeric Roofing, Built-up Bituminous Roofing, and Siding - round out the day-to-day scope of the job. A candidate who treats any one of these as optional risks both a failed exam attempt and real gaps on the jobsite.
| Exam Element | Detail |
|---|---|
| Scored questions | 60 |
| Time allowed | 120 minutes |
| Passing requirement | 45 correct (75%) |
| Possible unscored items | 1-10 experimental questions |
| Largest single domain | Steep Roofing (16 questions) |
From License to Livelihood: Career Paths After NV-C15
Once licensed, contractors generally branch into one of a few directions. Some stay as employees of an established roofing or siding company, becoming the named qualifier that lets that business legally operate under Nevada law. Others use the license to launch their own contracting business, taking on the separate requirements around financial documentation and bonding that sit outside the exam itself. Still others move toward specialized niches - commercial built-up bituminous roofing, elastomeric coating systems, or PV-integrated roofing - where the C-15 scope overlaps with growing demand.

You can also run full-length timed sessions on our practice test platform to see how your domain knowledge holds up under the actual 120-minute clock before you schedule the real thing.
Application Mechanics That Affect Your Job Start Date
Passing the exam is only part of the licensing sequence, and the surrounding mechanics directly affect when you can actually start working under your own license or as a company's named qualifier.
- Board approval precedes scheduling - you can't just register for the exam; the Board has to approve your application first.
- Application fee is $300, separate from the exam fee.
- Initial licensing and biennial renewal each cost $600, with Residential Recovery Fund charges billed separately.
- Six-month clock: required examinations must be completed within six months after the application is submitted.
- Retake spacing: a two-week wait is required between attempts, and three failures void the entire application - meaning you'd have to start the process over.
Beyond passing scores, licensing also requires experience verification, a resume or accepted alternative evidence, financial documentation, and applicable bonding - separate steps from the exam itself. The full eligibility picture is laid out in NV-C15 Requirements 2026: Eligibility, Prerequisites & How to Qualify, and testing windows are covered in NV-C15 Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Key Takeaway
Because three failed attempts void your entire application, treat your first sitting as the one that counts - don't schedule it before your weakest domains, especially Steep Roofing, are solid.

Frequently Asked Questions
No. The exam and licensing process are tied to Nevada State Contractors Board approval, not to a specific employer. Many candidates get licensed first and then pursue supervisory or contractor roles, while others are already working in the trade and licensing to formalize their position.
Steep Roofing, since it accounts for 16 of the 60 scored questions - more than any other domain. Sheet Metal and Flashing is a strong second priority given how often flashing knowledge applies across real jobs.
Retakes require a two-week wait and follow the same fee schedule as the original attempt ($95 for one portion or $140 for both). Three failures void the application entirely, requiring you to restart the process.
No. Those and other listed references are study-only. The only open-book material allowed during testing is the listed 2018 International Building Code.
No. This domain tests roofing-side knowledge related to PV installations, such as mounting penetrations and maintaining the roof envelope - not electrical licensing, which falls outside the C-15 trade scope.
