Lone Tree by the numbers

Lone Tree accounts for 72 of the contractor profiles in our Colorado records, ranking 122nd statewide, 16 of them with a lapsed license. An unusually high 78% show an active license, compared with 54% across Colorado.

Because Colorado leaves roofing, general contracting and HVAC to cities, we also pull municipal license lists. Lone Tree firms hold 32 licenses on them (Arvada (14), Aurora (14) and Thornton (4)), among them 3 roofing licenses, 15 general contractor licenses and 3 HVAC/mechanical licenses. Electricians make up the biggest group, with 40 electrical licenses (4 masters, 19 journeymen, 9 residential wiremen) and 15 plumbing licenses (5 masters, 3 journeymen). Experience runs deep: half of the licensed pros here were first licensed in 2017 or earlier, and 5 active licenses date from before 2000. 12 are new since 2024.

42 profiles are individual license holders rather than companies. The company on your contract should be one of the 5 active electrical or 4 active plumbing contractors, or a registered firm from a nearby city. 2 profiles carry a state board discipline flag (2 electrical), and 1 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.

HomeProFax profiles with a Lone Tree address, built from DORA electrical and plumbing rosters, the Aurora, Arvada and Thornton contractor license lists, Colorado Secretary of State filings and Boulder/Denver open permit data. Counts as of Oct 24, 2026.

Rather than checking each agency yourself, ask the contractor for their verified HomeProFax report. It covers license, discipline, permits and business standing in one link.

Licensing in Lone Tree

Colorado licenses electricians and plumbers statewide through the DORA State Electrical Board and the DORA State Plumbing Board. General contractors, roofers and HVAC contractors are licensed, if at all, by the local city or county. We haven't verified Lone Tree's local rules yet, so check with the building department before you hire. Most Lone Tree ZIP codes in our data are in Douglas County, so the city or Douglas County building department is where to ask.

Hail, roofs and your contract

Lone Tree 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).
