Key numbers
62 verified hail storms with stones of 1.75 inches or larger reached Douglas County, which includes Castle Rock, from 1991 to 2026 in the storm records we keep; the largest measured 4.25 inches (grapefruit size) on June 10, 2010 (NOAA NCEI).

A storm counts when the library lists Douglas County among the areas it hit. Each hail size is the storm's largest report, which may have fallen in a neighboring county, and insured losses cover every area the storm hit.
When storm crews flood Castle Rock after hail, narrow the field in this order: only consider contractors registered with the Town of Castle Rock, insist on a written contract that meets Colorado law, refuse any offer to cover your deductible, and choose the company with a real office nearby that will pull the Town permit and pass both inspections. Take your time. Your local roofers are not going anywhere, and the ones who are leaving are the ones to avoid.
The day after the storm
The first day brings a few trucks. The second brings dozens: local companies, metro Denver companies and out-of-state teams working your street with clipboards and door hangers. It can feel like an invasion. A “No Soliciting” sign helps; our Colorado Springs solicitor guide has a printable one that works anywhere. You do not need to decide anything at the door.
What the Town already requires
| Requirement | Why it helps you |
|---|---|
| Contractor registration before working in Town | A storm crew has to show a license from a testing jurisdiction and insurance naming the Town |
| Building permit before the roof is replaced | The Town checks the work, not just the paperwork |
| 100 percent tear-off, underlayment included, no overlays | No shortcuts hidden under new shingles |
| Mid-roof and final inspections | Problems are caught while the roof is still open |
| Permit expires with no inspection in 180 days | A contractor who disappears mid-job leaves a trail |

Signs of a storm chaser
- An offer to cover your deductible, called a discount, rebate or advertising fee. Colorado law (C.R.S. 6-22-105) forbids it.
- A “free” upgrade to Class 4 shingles. The cost comes from somewhere, often flashing or components that should have been replaced.
- A hotel or temporary address. Call the office number and ask where they are located.
- Insurance that only covers another state. Ask for a Colorado workers’ compensation certificate.
- No Town registration, or a permit pulled under another company’s name.
These are the same tactics we described in roofing scams after a Colorado Springs hailstorm.
Choosing among the good ones
- Read reviews on more than one site, and ask neighbors who replaced roofs after earlier storms.
- Ask whether the company works for you or for the insurer. The claim is yours; a good roofer documents the damage and makes sure nothing gets missed in the scope.
- Ask who supervises the crew and who answers warranty calls.
- If you love the look of wood, see choosing a cedar-look roof for your style before you pick a shingle.
- For the wider metro picture, read what local knowledge changes on a Denver-area roof.
