What the records show in Centennial

In Centennial, HomeProFax tracks 871 contractor profiles, which is the 19th-highest count for any city in Colorado, with ZIP 80112 home to the largest share. Active licenses: 670 of 871 (77%). The statewide rate in our data is 54%.

Because Colorado leaves roofing, general contracting and HVAC to cities, we also pull municipal license lists. Centennial firms hold 392 licenses on them (Aurora (194), Arvada (123) and Thornton (75)), among them 45 roofing licenses, 136 general contractor licenses and 31 HVAC/mechanical licenses. Board discipline: 34 Centennial records have a DORA discipline flag (27 electrical, 7 plumbing). 29 belong to licenses that are still active, so a current license alone doesn't rule out past discipline.

Electricians make up the biggest group, with 460 electrical licenses (66 masters, 220 journeymen, 40 residential wiremen) and 216 plumbing licenses (64 masters, 61 journeymen). Most entries are individual tradespeople (458), not companies. Only 83 active electrical contractor and 47 active plumbing contractor registrations are based here, and those are the businesses that can sell electrical or plumbing work to you directly.

Experience runs deep: half of the licensed pros here were first licensed in 2009 or earlier, and 82 active licenses date from before 2000. 83 are new since 2024. We matched 24 Centennial companies to Colorado Secretary of State filings: 17 in good standing and 7 delinquent or dissolved. A dissolved entity can't back a warranty, so check the status before you sign.

The busiest ZIP codes are 80112 (272), 80015 (194), 80122 (174), and 13 ZIPs are represented in total.

1,567 permits from City of Boulder and Denver open data trace back to 26 contractors based in Centennial. The leaders are Western States Fire Protection Company (532), Plumbline Services LLC (345), Haselden Construction LLC (141). The newest is dated 2026-10-14, and at least 130 were issued in the past year. Most are electrical permit (180), alteration/tenant finish (172), fire permit (103). These are jobs these firms did in Boulder or Denver. Centennial doesn't publish permits in a portal we cover yet, so no permits shown doesn't mean no permits pulled.

Hail, roofs and your contract

Centennial 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).
