Why this five minutes matters more than reviews
Nevada makes it unlawful to advertise as a contractor without a license, and requires the advertising to show the company name and license number (NRS 624.720). That means the license number is not private information — it's something a lawfully operating roofer is already required to show you. A license search converts that number into a real answer: active or not, roofing-authorized or not, and how large a job they're licensed to take.
The eight-step lookup
- Get the license number, not just the name. Ask the roofer directly, or find it on their advertising — Nevada law (NRS 624.720) requires a contractor's advertising to display it. A name-only search on the portal can return look-alike or lapsed entities, so the number is the reliable path.
- Open the NSCB public license search. Go to https://app.nvcontractorsboard.com. It's a standard state-agency web form — a manual lookup, not an instant API — budget about five minutes.
- Search by license number. Enter the number exactly as given. If nothing comes back, do not assume a typo — see the "no results" section below before contacting the roofer again.
- Confirm the license status is ACTIVE. Expired, suspended, revoked, and inactive all mean something different from active, and all mean don't hire based on this license alone.
- Confirm the classification covers roofing. Roofing work falls under NSCB classification C-15 (Roofing and Siding), specifically subclassification C-15a (NAC 624.320). A license active in an unrelated classification (say, general building) does not authorize roofing work.
- Check the monetary limit. Every Nevada license carries a monetary limit — the largest single contract the licensee may lawfully take. If your quote is above that limit, the licensee cannot lawfully perform the job at that contract price.
- Copy the exact business name shown. This is the only name that should appear on your written contract and your deposit check — not a trade name, not a truck-door brand. See the exact-name note below.
- Scan for disciplinary history. The record shows any complaints or board actions. One old, resolved complaint isn't automatically disqualifying — a pattern, or anything recent and unresolved, is worth asking the roofer to explain directly.

Reading what comes back
- Active, correct classification, monetary limit covers your job — the license clears; move on to the deposit-cap and exact-name checks below.
- Active, but a different classification — ask directly what work that classification covers and why they're quoting roofing. It may be a legitimate related license, or it may not authorize this job at all.
- Expired, suspended, or revoked — do not hire based on this license. A recently expired license may be a renewal-timing issue worth a direct question, but the burden is on the contractor to resolve it before you sign anything.
- No results at all — see the next section before assuming it's your typo.
If nothing comes up
Re-check the number character by character first — transposed digits are the most common innocent explanation. If a careful re-entry still returns nothing, try a name search as a cross-check. If it still doesn't resolve, that is a genuine red flag, not a website quirk — call the Nevada State Contractors Board (NSCB) — Reno office directly at 775-688-1141 before proceeding any further with that contractor.
Why the exact name on the record is worth writing down
Nevada's Residential Recovery Fund can reimburse a homeowner up to $40,000 per claim when a licensed contractor causes a loss — but claims have been denied where the homeowner paid a trade name or subsidiary brand instead of the exact business name on the license. Copy the name from the NSCB record verbatim, and make sure it is the name on your written contract and the payee on your deposit check. The full context, including a documented enforcement case, is in the contractor-vetting guide.
After the license clears
A clean license check is necessary, not sufficient. Still confirm: a deposit no larger than the lesser of $1,000 or 10% of the contract (NRS 624.970), a certificate of insurance you can verify with the carrier, and a written contract that includes the elements NRS 624.970 requires — the license number, a payment schedule, and a change-order clause. The full vetting guide covers all of it in order.
