Golf ball-sized hail struck Sioux Falls on May 31, 2026, producing 2-inch stones in the southeastern metro area.
The hail impact zone was located approximately 7 miles northeast of downtown Sioux Falls, affecting suburban residential areas.
Damage assessment
Two-inch hail represents the functional damage threshold for architectural asphalt shingles, the dominant roofing material in Sioux Falls. Golf ball-sized stones typically cause granule loss, exposed mat, and potential seal strip damage on standard shingles, particularly those over 10 years old. Class 4 impact-resistant shingles would likely sustain only cosmetic damage at this size. Functional damage is probable on older 3-tab shingles and wood shake roofing common in established neighborhoods.
With a typical 2% deductible on the median home value of $271,400, homeowners face a $5,428 out-of-pocket expense. Typical repair costs for a 2,000 square foot home range from $4,779 to $6,904, meaning most claims will exceed the deductible threshold. Filing makes financial sense given repair costs consistently surpass deductible amounts. Homeowners have six years from May 31, 2026 to file claims under South Dakota law.
South Dakota provides six years from May 31, 2026 to file insurance claims, with 2,191 days remaining as of the loss date.

Historical context
This event ranks #10 of 125 recorded hail events in the past decade for Minnehaha County. The largest recorded event remains 3.5-inch hail on August 6, 2021. May historically produces above-average hail activity with 37 events in 10 years, though peak season occurs later in August with 55 recorded events.
Storm system
This was part of a broader severe weather system affecting the region, with concurrent hail events reported in Brown County, SD, and Douglas and Dodge counties in Nebraska. Multiple 1.5-inch reports from neighboring areas suggest an organized supercell system.
Contractor guidance
Current contractor backlog is 4-8 weeks with high storm chaser risk expected within 24-48 hours. South Dakota SB 145, codified in SDCL Chapter 36-18A, prohibits contractors from advertising to pay insurance deductibles and provides homeowners a 72-hour contract cancellation right. Verify contractor licensing through the South Dakota Contractors Board and confirm current general liability and workers' compensation insurance before signing contracts.
Permits & building code
At 2-inch magnitude, repair rather than replacement is more likely for most homes. Contractors must pull permits costing $150-400, with inspections required. Class 4 shingles merit consideration given the 10-20% insurance discount and demonstrated hail resistance at this impact size.
