Roof Replacement — Colorado license requirements
01 The project
The starting point is the work itself — Roof Replacement in Colorado. The job determines which trades are involved, and the trades determine which license classifications may be required.
| Component | Trade |
|---|---|
| Roof cover system | Roofing |
02 Jurisdiction
This project is evaluated for Colorado — the two-layer state with no statewide general contractor license at all (a verified absence, not a gap). The state regulates exactly two trades, plumbing (C.R.S. Art. 155) and electrical (Art. 115), through DORA's Division of Professions and Occupations; general construction licensing is entirely local with six researched regimes, and the permit / inspection authority flips state ↔ local by job-site county. There is no statewide dollar threshold, bond or general-liability figure — each a verified absence — and registration conditions are workers' compensation + unemployment evidence only. Colorado jurisdiction page.
Permit fees, plan-review timelines, exemption lists and every locality beyond Denver, Aurora, Colorado Springs/PPRBD, Fort Collins, Larimer County and Jefferson County remain LOCAL_AUTHORITY_REQUIRED; PPRBD was unreachable all research day, so its license types, fees and exams are NOT_VERIFIED. The official C.R.S. host returns HTTP 403 to this environment, so statutory text was read on FindLaw's mirror retaining the official section anchors — a published limitation on the hub. Without a job-site location the local answer is NOT_DETERMINED, never a guess. 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.
This project has no project_classification rows for Colorado — that is a deliberate assertion, not a gap.
04 Scope
What the official sources say about the work involved — typed assertions, never a boolean "covers". Interpretations are marked as such.

| No statewide general contractor license — plumbing and electrical are the ONLY state-regulated trades (verified absence) DPO profession directory enumeration (read 2026-10-04) + C.R.S. §12-155-120(1)(a) and §12-115-107(2)(a) | license | Verified by enumerating the DPO program pages (read 2026-10-04): the Division of Professions and Occupations regulates exactly two construction professions — Plumbing and Electrical. Colorado has NO statewide general contractor license class, no state GC application regime and no state contract-registration regime: general building, remodeling, roofing, mechanical/HVAC, concrete, carpentry, painting, demolition, signs and pools are licensed by cities/counties/regional building departments, each with its own regime. The statutes themselves build the split in: C.R.S. §12-155-120(1)(a) exempts from state plumbing inspection any locality 'where the local entity … conducts inspections and issues plumbing permits', and C.R.S. §12-115-107(2)(a) lets localities adopt electrical standards 'more stringent than the minimum standards adopted by the board.' | S-CO-DPO-HOMESource S-CO-DPO-HOME — DORA — Division of Professions and Occupations (DPO)DORA Division of Professions and Occupations — profession directory — DPO profession directory enumeration (read 2026-10-04) + C.R.S. §12-155-120(1)(a) and §12-115-107(2)(a) Retrieved 2026-10-04 · last verified 2026-10-04 Read 2026-10-04 (full HTML served to direct fetches).

Denver, Aurora, Fort Collins, Larimer County, Jefferson County and the PPRBD region each license general construction locally (regimes seeded as REQ-CO-LOCAL-* rows with their own official sources), and permits and contractor licensing are SEPARATE in every one of them (the license authorizes the who; the permit authorizes the job and triggers inspection). The local treatment of the two STATE-licensed trades cannot be collapsed into one rule: exempt in Aurora/Larimer/JeffCo, extra license in the PPRBD region, Denver license PLUS the state card (see the six rows below). | S-CO-ELEC-APPSSource S-CO-ELEC-APPS — Colorado State Electrical BoardDPO Electrical — Applications (contractor registration, reciprocity, SB25-165) — DPO Electrical Applications verbatim (read 2026-10-04) https://dpo.colorado.gov/Electrical/Applications Retrieved 2026-10-04 · last verified 2026-10-04 Read 2026-10-04 (canonical URL confirmed in page HTML).

06 Rule: CO-NO-STATEWIDE-GC
Statewide licensing layer decision (verified absence): Colorado has NO statewide general contractor license — the Division of Professions and Occupations regulates exactly two construction trades, plumbing and electrical (verified by enumerating the DPO program pages). A caller states whether the work is a STATE-regulated trade; general construction, roofing, mechanical/HVAC, concrete, carpentry and painting answer at the LOCAL level, which stays NOT_DETERMINED without a jurisdiction. Missing facts yield NOT_DETERMINED.

General construction licensing in Colorado is LOCAL (DPO: 'For local requirements, contact the city and/or county government in the area in which you work').

09 No state roofing credential — the answer is entirely local
A standalone re-roof in Colorado touches NO state license: roofing is general construction, and Colorado licenses only plumbing and electrical statewide (verified absence — rule CO-NO-STATEWIDE-GC). What decides the job is the jurisdiction that issues the permit:
| Question | Colorado answer | Source |
|---|---|---|
| Statewide contractor license for roofing | none exists — verified absence across the DPO program pages; no dollar threshold either | S-CO-DPO-HOME |
| State roofing credential | none — Art. 155 covers plumbing, Art. 115 electrical; no third construction trade is licensed at the state level | S-CO-DPO-HOME |
| Who licenses roofers | the local jurisdiction: Aurora "Roofing Contractor / Subcontractor" (ICC), Fort Collins "Roofing, Roofing+" (F14 exam), Larimer "Roofers" $75 biennial, JeffCo roofing license $50/yr with an ICC exam, Denver's class ladder (A/B/C/D), PPRBD for the Springs region (license types NOT_VERIFIED) | S-CO-ELEC-APPS |
| Permit and inspection authority | the job-site county decides — in DPO-listed counties the local building department owns the permit; elsewhere the state inspects only plumbing/electrical (roofing permits are local) | S-CO-DPO-PERMIT-INFO |
| Homeowner re-roofing their own home | local permit first; the state's four-condition self-perform rule exists for plumbing/electrical components only — the roofing answer is the local owner-builder rule of that jurisdiction | S-CO-DPO-PERMIT-INFO |
| Without a job-site location | NOT_DETERMINED — which local regime applies is a LOCATION question; no rule guesses it | S-CO-ELEC-APPS |
The six researched local rows above (Requirements table) carry each jurisdiction's verbatim licensing text, fees and exams — never merged into one "Colorado roofing rule". Any other locality is LOCAL_AUTHORITY_REQUIRED. S-CO-ELEC-APPS
10 Permit and inspection layer
The state decides WHO MAY WORK at the two state trades; the job-site county decides who permits and inspects. DPO verbatim: "The State does not inspect in local jurisdictions having its own Electrical Inspection Program. You are responsible for determining the correct inspection authority." In DPO-listed counties: "If the county where your job site is located is listed below, do not continue with the permit application process…" State plumbing inspectors cover the 27 counties with no local program. S-CO-DPO-PERMIT-INFO
A permit is per JOB, a credential is per WHO: "A valid Colorado State Electrical permit must be obtained prior to installing electrical wiring" / "A valid Colorado State Plumbing permit must be obtained prior to installing plumbing", and work started first costs twice the prescribed permit fee (3 CCR 720-1 / 710-1). Local building permits (roofing, mechanical, general) follow each jurisdiction's own schedule — LOCAL_AUTHORITY_REQUIRED. S-CO-DPO-PERMITS
