Putnam, OK Hail Storm – July 2026

Putnam, Oklahoma experienced a mid-morning hail event on July 12, 2026. The multi-alert convective episode produced peak hail measuring 1.72 inches and has concluded.

What Happened

The multi-zone aggregate report for Putnam comprises three NWS alerts issued during the mid-morning period. The first alert issued at 7:55 AM CDT indicated 1.28-inch hail detected by dual-polarization radar. A subsequent NWS warning area at 8:29 AM CDT cited 0.88-inch hail reported as part of the warning. A final radar-detected alert at 8:57 AM CDT registered 1.58-inch hail on NEXRAD dual-polarization returns. The sequence shows repeated radar detections within the same metro area, with one NWS warning issued in the intervening period. The event is no longer active.

Damage Assessment

Radar-detected hail in the size range reported to Putnam can produce panel dents on parked vehicles and localized impact to exterior building components. Hail around and above one inch commonly strips granules from asphalt shingles, increasing near-term roof wear on older coverings. Glass elements with minimal protection, such as skylights and unshielded glazing, are at risk of cracking when struck by hail in this size class. Exterior HVAC condensers and exposed mechanical equipment can sustain visible dents and fins damage that reduce unit efficiency.

Photos and time-stamped notes taken immediately after the event are the most useful items for claims and repairs. Focus initial inspections on residential neighborhoods and commercial parking areas within the NWS warning area and on sites where radar detections were concentrated. Note the presence of vehicle fleet exposure and any visible roof granular loss or bruising of shingle tabs.

What Contractors Should Know

Prioritize safety and triage. Conduct a coordinated exterior-only inspection first while weather remains favorable. Use walk-through checklists that capture GPS location, roof type, approximate roof age, visible shingle damage, dented metal components, and damaged mechanical equipment. Tarp work should be limited to properties with actively leaking roofs or exposed interior finishes. Photograph every stage of the assessment, including wide-angle shots and close-ups with a scale object.

Prepare materials and estimates based on common damage patterns for the reported hail sizes. Carry replacement shingles, underlayment, zip screws, and basic flashing components. For mechanical units, document bent fins and provide condenser fin-straightening as a temporary measure when appropriate. Provide homeowners and facility managers with clear next steps: documented inspection report, prioritized repair scope, and an estimate for permanent repairs. Refer customers to the Strike Map for parcel-level hail track alignment; use the Strike Map to target inspections and to corroborate radar-detected impacts.
