Rapid City experienced golf ball-sized hail (1.75 inches) on May 31, 2026.
The hail strike occurred approximately 12 miles southwest of downtown Rapid City.
Damage assessment
Golf ball-sized hail at 1.75 inches typically causes moderate damage to standard architectural asphalt shingles, the dominant roofing material in Rapid City. This magnitude generally produces functional damage including granule loss, exposed mat, and potential cracking that affects the roof's weatherproofing ability. Roofs over 10-15 years old are particularly vulnerable to this size impact. Class 4 impact-resistant shingles would likely sustain only minor cosmetic damage at this hail size.
With a typical deductible of $5,400 (2% of median home value $270,000) and repair costs averaging $5,632 for a 2,000 square foot roof, filing a claim makes marginal financial sense with only $232 in net benefit. Homeowners have six years from the loss date to file under South Dakota law. The tight margin between deductible and repair cost makes thorough damage assessment critical before deciding whether to file.
South Dakota provides six years from the loss date to file insurance claims, giving homeowners until May 31, 2032 to take action.

Contractor guidance
Current contractor backlogs in Rapid City are running 2-4 weeks with moderate storm chaser activity expected following this event. South Dakota SB 145, codified in SDCL Chapter 36-18A, prohibits contractors from advertising or promising to pay insurance deductibles, and any contracts violating this are void. Homeowners also have a 72-hour right to cancel roofing contracts after insurance denial notice. Verify contractor licensing and avoid any deductible waiver offers, as these violate state law.
Permits & building code
At 1.75 inches, repair rather than full replacement is most likely for affected properties. Permits typically cost $150-$350 for roofing work in this area. Given the 10-20% insurance discount for Class 4 shingles and their superior hail resistance, upgrading during repair could provide long-term value in this moderate-risk area.
