Westminster contractors at a glance

Count every licensed electrician, plumber and city-listed contractor with a local address and Westminster comes to 1,394 profiles (11th in Colorado), based on state and city license records. 319 Westminster business licenses sit on city lists (Arvada (134), Aurora (117) and Thornton (68)), the only public record for trades the state doesn't license. That includes 37 roofing licenses, 42 general contractor licenses and 38 HVAC/mechanical licenses.

Electrical and plumbing licenses, which Colorado issues at the state level, account for 1,292 of these records: 874 electrical licenses (114 masters, 490 journeymen, 72 residential wiremen) and 418 plumbing licenses (110 masters, 187 journeymen). That is the 11th-largest electrical workforce in our Colorado data. 47 profiles carry a state board discipline flag (32 electrical, 15 plumbing), and 28 of those licenses are still active. A flag can mean anything from a paperwork lapse to a serious finding, so read the board record behind it. For electrical or plumbing jobs, the business you sign with needs a contractor registration. Westminster has 82 active electrical and 55 active plumbing registrations; the other 1,002 individual licenses belong to workers, not firms.

About 58% are active, in line with the 54% we see statewide, and 579 records have lapsed. We matched 42 Westminster companies to Colorado Secretary of State filings: 32 in good standing and 10 delinquent or dissolved. A dissolved entity can't back a warranty, so check the status before you sign. Experience runs deep: half of the licensed pros here were first licensed in 2004 or earlier, and 102 active licenses date from before 2000. 133 are new since 2024.

The busiest ZIP codes are 80031 (372), 80030 (365), 80021 (290), and 19 ZIPs are represented in total.

Hail, roofs and your contract

Westminster 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).
