Windsor by the numbers

The Windsor file in our Colorado data runs to 430 contractor profiles, 29th among all cities in the state, with ZIP 80550 home to the largest share. 69% of them show an active license on file, above the Colorado-wide figure of 54% for the profiles we hold.

Roofers, general contractors and HVAC firms aren't state-licensed in Colorado, so they show up only through city license lists. 57 Windsor-based profiles appear on the lists we hold (Aurora (24), Thornton (18) and Arvada (15)), including 9 roofing licenses, 9 general contractor licenses and 2 HVAC/mechanical licenses. Electrical and plumbing licenses, which Colorado issues at the state level, account for 405 of these records: 248 electrical licenses (46 masters, 116 journeymen, 29 residential wiremen) and 157 plumbing licenses (37 masters, 59 journeymen).

Most entries are individual tradespeople (306), not companies. Only 32 active electrical contractor and 28 active plumbing contractor registrations are based here, and those are the businesses that can sell electrical or plumbing work to you directly. Board discipline: 13 Windsor records have a DORA discipline flag (7 electrical, 6 plumbing). 9 belong to licenses that are still active, so a current license alone doesn't rule out past discipline.

Experience runs deep: half of the licensed pros here were first licensed in 2008 or earlier, and 48 active licenses date from before 2000. 48 are new since 2024. We matched 9 Windsor companies to Colorado Secretary of State filings: 4 in good standing and 5 delinquent or dissolved. A dissolved entity can't back a warranty, so check the status before you sign. Profiles cluster in ZIP codes 80550 (421), 80528 (7), 80205 (1), out of 4 ZIPs on file.

Hail, roofs and your contract

Windsor 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. RMIIA's costliest-storm list includes the May 22, 2008 Windsor tornado at $193.5 million 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).
