Rolla, KS Hail Storm – July 2026

Rolla, KS experienced a concluded hail-producing thunderstorm on July 3, 2026, producing up to 1.88 inches of hail and tracking across the metro from late afternoon into early evening.

What Happened

The event generated eight NWS alerts between 3:40 PM CDT and 6:26 PM CDT. Alerts and detections were as follows:

• 3:40 PM CDT – 1.47-inch hail detected by dual-polarization radar.
• 3:43 PM CDT – 1.47-inch hail detected by dual-polarization radar.
• 4:23 PM CDT – 1.75-inch hail detected by dual-polarization radar.
• 4:36 PM CDT – 1.34-inch hail detected by dual-polarization radar.
• 4:47 PM CDT – 1.25-inch hail reported in an NWS warning only.
• 5:23 PM CDT – 1.50-inch hail detected by dual-polarization radar.
• 5:44 PM CDT – 1.06-inch hail detected by dual-polarization radar.
• 6:26 PM CDT – 1.01-inch hail detected by dual-polarization radar.

Radar coverage shows the hail path moved across the Rolla metro in a generally eastward progression during late afternoon and into early evening. Several alerts were radar-detected; one alert at 4:47 PM CDT relied on the NWS warning polygon without a dual-polarization radar detection in the alert payload.

Damage Assessment

Alert sizes recorded in the Rolla metro ranged from about 1.0 to 1.75 inches on radar, with the single NWS-warning-only alert at 1.25 inches. Hail in that range commonly produces visible denting to vehicle panels, localized damage to asphalt-shingle roofing such as granule loss and bruising, and impacts to external HVAC components and soft vinyl siding where exposure occurred. The timing over late afternoon increased the likelihood of vehicles parked outdoors being struck during commute and evening activities in residential and commercial areas of the metro.

Field reports of specific structural failure or widespread roof loss are not included in the alert sequence. Inspections should prioritize locations along the mapped hail path in Rolla, focusing first on properties with visible shingle granule scatter, dented metal, or compromised rooftop equipment.

What Contractors Should Know

Begin with a safety-first field triage. Confirm power is off at any worksite with damaged rooftop equipment or fallen lines. Prioritize tarping and temporary closures where interior water entry is present. On roofs, document granule loss, broken shingles, and ridge and valley condition with time-stamped, geotagged photos. Record measured hail fragments if retained by property owners; note the collection time and exact location within the Rolla metro.

For scope and scheduling, expect a concentration of service calls for dent removal, asphalt shingle replacement, and HVAC repairs following this event. Prepare estimates that separate cosmetic auto or siding dents from structural roof replacement. Maintain clear documentation for insurance claims, including the alert timeline and radar-detected sizes. Triage high-value properties and properties reporting active leaks first.
