Sources, method and corrections
Last updated .
Every price range and rule on this site names where it came from and the day we read it. This page lists those sources, explains how we gather Denver price data, and tells you how to report an error. It applies to the Denver roofing guide and to the disclosure.
Rules we write by
- Every cost figure carries its source and the date we read it. We publish no cost figure of our own until our quote log holds at least twelve dated Denver-metro quotes for that cell; until then the site shows published ranges from named sources and says so.
- Where we can count something ourselves from a public dataset, we do. The hail figures on this site were counted from NOAA's raw Storm Events detail files for 2016–2025 across the seven metro counties, not copied from another roofer's page.
- Regulatory statements (licensing, permits, contract law, insurance, tax) name the authority and, where we could not confirm the current text on the authority's own site, carry a "verify" mark.
- No invented people. There is no named reviewer on this site yet; when a licensed Denver roofing contractor, building inspector or insurance professional reviews a section, their name and license appear on it and nowhere else.
- The last-reviewed date changes only when the content changes.

Common questions about our sourcing
Why does the site publish other people's price ranges instead of its own?
Because a price we have not gathered is a guess. Our rule is at least twelve dated Denver quotes for a given material and size before we publish a figure as ours. Until the quote log reaches that, we show what named Denver roofing companies and cost guides have put in print, with the date each page carried when we read it.
What does the "verify" mark mean?
That we could not confirm the current wording on the authority's own website, usually because the page is a PDF, a portal, or a guidance document older than the code edition now in force. The statement reflects the best available source, and you should confirm it with the authority named before you rely on it. Denver's residential roofing guidance is a good example: the document we cite is dated 2015 and refers to an older code cycle, while the city has since adopted a newer building code.
Why is there no named reviewer?
Because we have not recruited one. A byline from a licensed roofing contractor, a building inspector or an insurance professional appears only when a real person has reviewed the section, and never before.
