What the records show in Castle Rock

Castle Rock ranks 22nd among Colorado cities by contractor profiles in HomeProFax, with 728 businesses and licensed tradespeople listed at local addresses, based on state and city license records. Because Colorado leaves roofing, general contracting and HVAC to cities, we also pull municipal license lists. Castle Rock firms hold 179 licenses on them (Aurora (110), Arvada (50) and Thornton (19)), among them 24 roofing licenses, 46 general contractor licenses and 19 HVAC/mechanical licenses.

67% of them show an active license on file, above the Colorado-wide figure of 54% for the profiles we hold. By trade, the DORA records give Castle Rock 440 electrical licenses (78 masters, 194 journeymen, 54 residential wiremen) plus 197 plumbing licenses (56 masters, 60 journeymen).

Companies are a minority: 49 active electrical contractor and 44 active plumbing contractor registrations, against 463 individual tradespeople. Board discipline: 14 Castle Rock records have a DORA discipline flag (8 electrical, 6 plumbing). 8 belong to licenses that are still active, so a current license alone doesn't rule out past discipline.

The median first-license year is 2008. 188 records predate 2000, and 73 licenses were first issued in 2024 or later. We matched 18 Castle Rock companies to Colorado Secretary of State filings: 10 in good standing and 8 delinquent or dissolved. A dissolved entity can't back a warranty, so check the status before you sign. Profiles cluster in ZIP codes 80104 (445), 80109 (168), 80108 (111), out of 7 ZIPs on file.

Permit history: 7 Castle Rock-based contractors have 21 permits on file from City of Boulder and Denver open data, and at least 4 of the listed permits were issued in the last 12 months (latest 2026-08-10). Most permitted: Green Frontier Electric Ltd (7), Full House Construction and Design, Inc. (5), Lakewood Electric Co., Inc. (4). Common types: electrical permit (6), alteration/tenant finish (5), 4 - alteration (5). These are jobs these firms did in Boulder or Denver. Castle Rock doesn't publish permits in a portal we cover yet, so no permits shown doesn't mean no permits pulled.

Castle Rock licensing rules, with sources

Local authority: Town of Castle Rock Development Services. What we verified on official pages (Oct 2026):

• Castle Rock requires contractors to register with the Town before covered work and before applying for a building permit. (source)
• Castle Rock registration asks for a qualifying ICC-equivalent municipal contractor license for applicable classes, liability insurance naming the Town, and workers' compensation where applicable. (source)
• Electrical and plumbing contractors in Castle Rock also need the required Colorado state license. (source)

Electricians and plumbers are also licensed statewide by the DORA State Electrical Board and the DORA State Plumbing Board. Rules and fees change, so confirm with the department before you sign.

Hail, roofs and your contract

Castle Rock sits on the Front Range, in the heart of "Hail Alley." The Rocky Mountain Insurance Information Association says the region usually sees three or four catastrophic hailstorms a year, and the damaging season runs from mid-April to mid-September. Eight of the twelve costliest Colorado hailstorms on RMIIA's list were centered on the Denver metro, led by the May 8, 2017 storm at $2.3 billion in insured losses. After a storm, Colorado law lets you cancel an insurance-paid roofing contract within 72 hours of a written claim denial (C.R.S. 6-22-104), and a roofer may not offer to pay or waive your deductible (C.R.S. 6-22-105).
