Hail alerts for your address
An email when hail an inch or larger is reported near your house, so you know to take a look before a roofer knocks on your door.
How the alerts work
- Where the reports come from. NOAA's Storm Prediction Center publishes preliminary storm reports from trained spotters, emergency managers and the public through the day. We check them every 30 minutes from April through September and every 6 hours the rest of the year.
- What triggers an email. A Colorado report of hail 1 inch across (about quarter size) or larger, inside the distance you picked. That cut-off is our choice, not an official damage threshold.
- How often. At most one email per storm day for each address, with the largest hail reported, how far away it was and when.
- What's in it. What to check from the ground, a link to our after-the-storm checklist, and your address's hail history in the Roof Report.
A report near you doesn't mean your roof was damaged, and no report doesn't mean it wasn't. Reports are unverified when they first come in, can be revised, and depend on someone seeing the hail, so rural and mountain areas are undercounted.
Colorado's damaging hail season runs roughly mid-April to mid-September, and the Front Range sees some of the most frequent large hail in North America, according to the Rocky Mountain Insurance Information Association. If a roofer shows up after a storm, remember that you can cancel a residential roofing contract within 72 hours of signing it under C.R.S. 6-22-103. More in hiring a roofer.
