Hail in Calhan, CO on August 20, 2024
Radar-estimated up to 1.25" (half dollar size)
Weather radar estimated hail of up to 1.25" (half dollar size) over Calhan between 6:03 PM and 6:27 PM, from 10 separate radar hail signatures inside the town. No spotter or NOAA ground report was filed inside the town that day, which is common: most hail falls where nobody is measuring it.
What half dollar-size hail does to a roof
Hail in this range commonly bruises asphalt shingles and knocks off the protective granules. The roof may look fine from the street and still have lost years of life; soft metals like vents and gutters usually show the dents first. Radar describes the storm, not your shingles: the only way to know what a particular roof took is an inspection. Most homeowner policies set a deadline for reporting storm damage, so check your policy.
Every home inside a storm's radar footprint, scored by roof age, material and hail history, sold to a few roofers only so you are not the twentieth truck on the street.

Radar sizes are estimates from NEXRAD hail signatures (NOAA Severe Weather Data Inventory) for the largest stones in a storm cell, not a measurement at any one home. Ground reports are National Weather Service local storm reports and the NOAA Storm Events Database, as filed. Town-level data only; this page shows no addresses and no homeowner information.
