01 The project

The starting point is the work itself — Roof Replacement in Nevada. The job determines which trades are involved, and the trades determine which license classifications may be required.

02 Jurisdiction

This project is evaluated for Nevada — a state that requires a contractor license at any price: NRS 624.700 makes it unlawful to engage in the business or act as a contractor, or to submit a bid, without an active license, and an unlicensed bid or contract is void ab initio. There is no statewide dollar threshold anywhere (a verified absence), the license belongs to the business and is qualified by an individual, the classification scopes live in the NAC, the Board sets a monetary ceiling and a mandatory bond — and NRS 624.035 lets every county and city require MORE. Nevada jurisdiction page.

Limitation — the local layer is not researched beyond Las Vegas

Permit fees, plan-review timelines, exemption lists and every other city's rules were researched ONLY for the documented City of Las Vegas example (state license + city business license gate contractor permit issuance); every other Nevada locality remains LOCAL_AUTHORITY_REQUIRED, and Clark County runs its own building department (named, not researched). The official NRS/NAC host returns HTTP 403 to this environment, so statutory text was read on a non-commercial mirror retaining the official section anchors — a published limitation on the hub. State requirements are not the complete story for any locality.

03 Trade → license

Relations below are recorded per state — only this jurisdiction's classifications are shown.

Trades involved: Roofing.

May require C-15 — Roofing and siding confirmed S-NV-NAC-320 rule NV-ROOFING-CLASS
C-15a ROOFING verbatim scope covers the roof cover (asphalt … shingles … tile … slate … urethane, and photovoltaic roof tiles intended to serve in place of other existing roofing materials) — but NOT conduits, inverters, batteries or electrical connections (those are C-2g). A standalone re-roof is single-trade specialty work → C-15; the $1,000 repair exemption (NRS 624.031(6)) fails for any real re-roof on at least two independent carve-outs (building permit normally required (a); HSW-affecting classification work (c)) plus the value test outright — license required in practice. Roof DECKING/truss repairs are C-3a (NAC 624.210). Local permit: LOCAL_AUTHORITY_REQUIRED (research §L.1).

06 Rule: NV-ROOFING-CLASS

Which classification the roof work needs: the roof COVER (installation/application/alteration/repair of watertight, weatherproof roof materials incl. photovoltaic roof tiles replacing existing roofing) is C-15a under primary C-15; electrical work beyond the service panel is C-2g (C-15a expressly excludes conduits, inverters, batteries and electrical connections); roof decking/truss/sheathing repair is C-3a. Missing facts yield NOT_DETERMINED.

Outcome	Conclusion	Caveats
c15a-roofing	c15a_roofing_classification_required	The $1,000 repair exemption (rule NV-REPAIR-EXEMPT) normally fails here: a re-roof requires a permit (carve-out (a)) and roof-cover work sits in a health/safety/welfare classification (carve-out (c)). Roof DECKING/truss/sheathing repair is C-3a (NAC 624.210), not C-15a. Local building permit: LOCAL_AUTHORITY_REQUIRED.
c15a-plus-c2g	c15a_and_c2g_required	Three-way solar boundary: PV roof tiles = C-15a; PV electrical equipment = C-2g; solar THERMAL = C-37 (NAC 624.540). NRS 624.970 does not govern residential photovoltaic contracts (excluded at 624.970(7)(d)) — PV contract rules live in NRS 624.855, NOT read this phase; the solar project page is withheld for that reason.
deck-repair-c3	c3a_carpentry_classification_required	If BOTH the deck and the cover are being replaced, the job spans C-3a and C-15a — two primary classifications ($300 additional-classification application if not already held). HSW-affecting work may also trigger the NRS 624.031(6)(c) carve-out (exemption unavailable).

07 Rule: NV-LICENSE-REQUIRED

Statewide licensing decision (NRS 624.700): it is unlawful to engage in the business or act in the capacity of a contractor in Nevada, or to submit a bid on a Nevada job, without an ACTIVE license — and a bid or contract submitted in violation is void ab initio. There is NO statewide dollar threshold (verified absence): license is required for construction/alteration regardless of price, subject only to the NRS 624.031 exemptions (SEPARATE rules NV-REPAIR-EXEMPT, NV-OWNER-BUILDER). Missing facts yield NOT_DETERMINED.

Outcome	Conclusion	Caveats
license-required	statewide_license_required	There is NO Nevada dollar threshold — price never decides this question (verified absence, REQ-NV-NO-THRESHOLD-001). The twelve NRS 624.031 exemptions were NOT evaluated here — check rules NV-REPAIR-EXEMPT and NV-OWNER-BUILDER (set exemption_applies only from those tests). Penalties for unlicensed contracting: 1st misdemeanor ≤ $1,000/≤ 6 months; 2nd gross misdemeanor $2,000–$4,000/≤ 1 year; 3rd+ category E felony $5,000–$10,000/1–4 years (NSCB FAQ). Locales may require an ADDITIONAL license (NRS 624.035) — permits stay LOCAL_AUTHORITY_REQUIRED.
license-already-held	license_already_held	Holding a license is not holding THE RIGHT classification — out-of-class work follows NRS 624.220(4) (rule NV-SPECIALTY-INCIDENTAL). The bond must be continuous and the license active (NRS 624.270/624.283).
exempt	exempt_from_licensure	Exemptions are narrow and conditional — NEVER set exemption_applies = true without evaluating the specific NRS 624.031 item's conditions. Even exempt persons may NOT advertise as contractors (NRS 624.720(1) — rule NV-ADVERTISING). Local permits, codes and any local licensing still apply.
not-contracting	outside_chapter_624_activity	Material suppliers who do not fabricate/consume materials are outside the definition (NRS 624.020(3)); subcontractors and specialty contractors are INSIDE it.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-624-700 S-NV-624-020 S-NV-FAQ

08 Rule: NV-REPAIR-EXEMPT

NRS 624.031(6): repair/maintenance work under $1,000 including labor and materials is exempt — UNLESS any of FIVE carve-outs applies: (a) a permit is required; (b) plumbing, electrical, refrigeration, heating or air-conditioning work; (c) work in a health/safety/welfare classification; (d) part of a larger project valued $500+ or split-contract evasion; (e) performed by a licensee or their employee. Each carve-out is its own hard outcome. The board's '$500 or more must be licensed' sentence (CONFLICT-NV-001) is NOT encoded — statute governs. Missing facts yield NOT_DETERMINED.

Outcome	Conclusion	Caveats
repair-exemption-applies	repair_exemption_applies	All seven facts must be present and true — the exemption collapses on ANY carve-out (separate outcomes name each one). CONFLICT-NV-001: the NSCB Owner-Builder page says '$500 or more … must be licensed' — the statutory $1,000 test governs the rules; the board sentence is published beside it, unresolved. Local permits/codes unaffected — and if a permit WOULD be required, carve-out (a) already removed this exemption.
carveout-permit	exemption_defeated_by_carve_out	A permitted job is licensed work regardless of its dollar value.
carveout-trade	exemption_defeated_by_carve_out	HVAC and water-heater work always fall here — the $1,000 exemption never covers them (project pages).
carveout-hsw	exemption_defeated_by_carve_out	Which classifications the Board prescribes as HSW-affecting was NOT read verbatim this phase — the caller must supply the classification fact (research §O).
carveout-larger-project	exemption_defeated_by_carve_out	The $500 figure appears in the STATUTE only as this evasion test — it is not a licensing threshold (see CONFLICT-NV-001).
carveout-licensee	exemption_defeated_by_carve_out	A licensee's own work is never 'exempt work' — it must sit inside their classification or use the NRS 624.220(4)(b) out-of-class relief (rule NV-SPECIALTY-INCIDENTAL).
not-repair-work	repair_exemption_not_available	Other NRS 624.031 items (owner-builder, material-only, public work, agriculture…) are separate tests — this outcome only closes the repair path.

Rule confidence: confirmed. Missing inputs produce NOT_DETERMINED — never a forced answer. Sources: S-NV-624-031 S-NV-624-700

09 C-15a ROOFING — the verbatim scope, and why the $1,000 exemption fails

A standalone re-roof is single-trade specialty work: C-15 ROOFING, whose C-15a subclassification is written verbatim in NAC 624.320 — roof covering work including asphalt, shingles, tile, slate, urethane, and photovoltaic roof tiles intended to serve in place of other existing roofing materials. S-NV-NAC-320

Question	Nevada answer	Source
Statewide contractor license	required at any price — NRS 624.700, no dollar threshold anywhere	S-NV-624-700
$1,000 repair exemption (NRS 624.031(6))	fails a real re-roof on independent carve-outs — a building permit is normally required (a) and re-roofing is classification work significantly affecting health, safety and welfare (c) — plus any re-roof ≥ $1,000 fails the value test outright	S-NV-624-031
Credential for the roof cover	C-15 (C-15a ROOFING); a B-2/B-7 prime may contract the job and subcontract the roofing	S-NV-NAC-320
PV beyond the roof tile (conduits, inverters, batteries)	C-2g — C-15a does not include them	S-NV-NAC-200
Roof decking / truss repairs	C-3a (carpentry)	S-NV-NAC-210
Local building permit	LOCAL_AUTHORITY_REQUIRED — Las Vegas example: state license + city business license gate permit issuance	S-NV-LV-FEE-EST

Roofing done as part of a remodeling contract sits with the B-7/B-2 prime (research §L.1); the licensed contractor's out-of-class relief (NRS 624.220(4)(b), < $1,000 and no permit) never rescues an unlicensed crew on a job that needs a permit — which a re-roof almost always does. S-NV-624-220

10 Local permit layer

The state decides WHO MAY CONTRACT; the local authority decides permits, inspections, fees and any local business license. NRS 624.035 expressly lets each county or incorporated city require an additional contractor's license "subject to the applicant meeting such additional standards as are reasonable and necessary for the protection of the public" — the OPPOSITE of Georgia's preemption. NRS 624.970(6): the residential contractor "shall apply for and obtain all necessary permits." S-NV-624-035

The researched local example is the City of Las Vegas (LOCAL EXAMPLE — NOT STATEWIDE): "Only a Nevada licensed contractor may obtain a building permit for commercial construction" and "A valid Nevada State Contractor's license and city of Las Vegas business license are required for the issuance of permits to contractors" — the state license and a city business license both gate permit issuance, and the page publishes example local fees (labeled examples, never a fee schedule). S-NV-LV-FEE-EST

Permit fees beyond those labeled examples, exemption lists, timelines and every other city's or county's rules are LOCAL_AUTHORITY_REQUIRED.
