April 27–May 4, 2026: Hail Events and Strike Maps for Contractors

Week in Review

Roofing and exterior contractors: fifteen hail events were detected across Missouri, Texas, Indiana, Kentucky, and nearby counties during April 27–May 4, 2026. Total residential and commercial address counts inside impacted footprints sum to 306,600 addresses. Events ranged from isolated 1.75-inch reports to multiple 4-inch-plus occurrences. Detection sources include dual-polarization radar and spotter-verified ground reports.

This week had two clear operational themes. First, concentrated large-hail reports occurred on April 27–28 across northeastern and central Texas and portions of Missouri. Second, a high-address impact event occurred in southeast Missouri on April 27. Both themes will influence canvass sequencing and crew allocation for the next 72–96 hours.

All entries list recorded maximum hail diameter, date, and the address count within the radar-derived impact footprint or spotter-verified area. Address counts reflect the number of deliverable locations inside the detected footprint.

Regional Patterns

Missouri and Texas accounted for 11 of the 15 detected events. Southeast Missouri produced the largest single-address footprint. Sainte Genevieve, MO contained 195,859 addresses inside the radar-derived footprint on April 27. That event shapes regional canvass volume and prioritization.

North-central Texas nights of April 28–29 produced several large-hail reports clustered around Cleburne, Godley, Riesel, and Franklin. Recorded maximums included 4.5-inch hail in Cleburne and Godley. Those events carry concentrated, high-severity exposures in relatively compact footprints. Big Wells and Del Rio saw separate 4-inch class reports on April 30–May 1 in southwest Texas. Those footprints are smaller in address count but show peak sizes above 4 inches.

Boonville, IN and Calhoun, KY each registered multi-inch hail on April 27 with materially different address counts. Boonville’s detection covered 38,561 addresses. Calhoun’s detection covered 6,345 addresses. Both events are candidates for prioritized canvass where local competition is lower and lead conversion windows narrow.

Several radar-detected events returned zero addresses inside the detection polygon. Cleburne (3.00-inch), Miami, MO (2.00-inch), and Willow Springs, MO (2.75-inch, spotter-verified) fell outside populated address clusters. These may still merit targeted field checks if customer reports appear or insurance activity is reported.

What Contractors Should Watch

Prioritize canvass sequencing by combining address count with peak hail diameter. Sainte Genevieve, MO – 195,859 addresses on April 27 – is the highest volume target this week. Assign high-capacity crews and plan for multi-day canvass windows there.

Secondary priority targets by combined size and address count:

• Godley, TX – 4.50-inch hail – 37,167 addresses – focus early deployment on roofing assessment teams.
• Boonville, IN – 2.00-inch hail – 38,561 addresses – allocate rapid-response inspection crews for tarps and estimates.
• Cleburne, TX – 4.50-inch hail – 7,806 addresses – deploy adjuster liaison teams and document large-scatter damage signatures.

Tertiary targets with concentrated peak sizes and mid-range address counts:

• Elkland, MO – 4.00-inch hail – 7,358 addresses.
• Willard, MO – 4.75-inch hail – 6,672 addresses.
• Del Rio, TX – 4.37-inch hail – 90 addresses.
• Big Wells, TX – 4.00-inch hail – 3,058 addresses.

Use spotter-verified events to validate quick knock-and-talk canvasses. Windthorst, Riesel, and Calhoun all include spotter confirmation that can reduce drive-time uncertainty. Prioritize those where address counts exceed 1,000.

Defer low-address or zero-address radar detections unless phone leads, insurance MVRs, or customer calls appear. Examples include the 0-address Cleburne 3.00-inch detection, Miami, MO, and Willow Springs where ground truth is limited.

Logistics and crew safety notes:

• Stage materials and crews closer to the largest footprints to reduce driving time. Sainte Genevieve and Boonville justify temporary staging.
• Expect extended documentation needs where peak sizes exceed 4 inches. Photograph vehicles, HVAC units, and siding in addition to roofs.
• Coordinate with adjusters on larger clusters to prevent duplication of estimates.

Forward-looking note

Synoptic models indicate a lower-amplitude pattern for the coming week with isolated instability over the southern Plains and a midweek return of elevated moisture eastward. Monitor convective outlooks and local warnings for isolated severe potential. Prioritize flexible crew schedules and maintain staging near the largest current footprints to enable rapid response if additional cells track into the same corridors.
