Hail in Black Forest, CO on September 17, 2025
Radar-estimated up to 1" (quarter size)
Weather radar estimated hail of up to 1" (quarter size) over Black Forest between 3:48 PM and 4:00 PM, from 2 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 quarter-size hail does to a roof
One inch is the size where insurers and roofers start to expect shingle damage, especially on older roofs. Look for dented gutters and downspouts and granules collecting at the bottom of the downspouts. 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.
