Hastings, IA Hail Storm – August 2026

Hastings, IA recorded a multi-zone hail event on August 4–5, 2026, with peak hail reaching 2.37 inches in diameter. The storm moved through the metro from late evening into the early morning and has concluded.

What Happened

The event began with an NWS warning issued at 11:31 PM CDT on August 4 for 0.75-inch hail. Warnings continued through the night for the Hastings metro, totaling 13 NWS alerts spanning 11:31 PM on August 4 through 6:55 AM on August 5. Dual-polarization radar first detected larger hail at 12:18 AM CDT on August 5, with radar-derived hail sizes increasing to 1.19 inches and then to 1.71 inches within the next ten minutes. Radar detections continued, peaking in the overnight hours with multiple radar-derived reports near and above 1.5 inches; several later NWS warning-only alerts repeated 1.0-inch and smaller hail as the storm moved east. The storm produced a distributed hail footprint across the Hastings warning area rather than a single narrow corridor. The event is now concluded and no active warnings remain for this system.

Damage Assessment

Hail in the Hastings warning area ranged from about 0.75 inch to 2.37 inches in diameter. Hail at the lower end of this range typically causes cosmetic dents to vehicles and superficial damage to siding and soft metals. Hail around 1.0–1.5 inches increases the likelihood of broken glass, dented panels on vehicles, and granular loss on shingled roofs. Hail above 2.0 inches elevates the risk of significant shingle fracture, exposed underlayment, skylight and window damage, and vehicle glass breakage. For the Hastings metro, expect the greatest roof and vehicle exposures in areas under the radar-detected hail swath during the midnight–predawn hours. Document visible shingle granule loss, cracked panels, and any glazing damage with dated photographs and location notes to support repair assessments.

What Contractors Should Know

Prioritize safety and rapid documentation. Conduct an exterior inspection in daylight where possible and avoid rooftop work until surfaces are dry and ladders are secure. Photograph damage with a measurable scale and capture the surrounding neighborhood context. Check roof shingles for fractures, missing tabs, and exposed felt. Inspect vents, gutters, skylights, soffits, and soft-metal trim for deformation. Note that hail embedded in landscaping or on vehicles can also indicate localized peak sizes.

Estimate repair scope by hail size and pattern. For roofs with widespread shingle fracture or missing granules paired with 2-inch-plus hail detections, advise clients that a full replacement is often more durable than piecemeal patching. For isolated dents and cosmetic siding damage, prioritize sealing and paint touch-up to prevent accelerated wear. Collect timestamped photos and a concise itemized scope for insurer submissions. Coordinate with vehicle repair shops for glass- and body-damage claims when 1.5-inch-plus hail is observed.
