Baseball-sized hail detected near Rapid City, SD on August 23, 2026
Hail was detected at a radar-indicated point within the Rapid City monitoring area. Actual impact can vary by neighborhood, so nearby homes should use this as a signal to check roofs, gutters, siding, and vehicles.
Damage assessment
The radar-confirmed strike landed approximately 14 miles west of downtown Rapid City, with one hail report logged in Pennington County that day. At 3.5 inches, this is not a borderline event — hail at this size causes functional damage to architectural asphalt shingles regardless of age, meaning granule loss, cracked tabs, and compromised waterproofing are expected outcomes, not possibilities. Older shingles, particularly those past 15 years, face a higher likelihood of full replacement rather than patch repair. For context, the largest recorded event in Pennington County reached 4.5 inches on August 26, 2021, so this storm falls below that peak but well above any functional-damage threshold.
On a $270,000 home with a 2% deductible, the out-of-pocket threshold before insurance contributes is $5,400. Typical repair cost for a 2,000 square foot roof runs $5,962, with a range of $4,878 to $7,047 depending on pitch, materials, and labor. Get a professional inspection before making any insurance decisions.
At these numbers, the typical repair cost exceeds a standard 2% deductible. Contact your insurer — damage at this level is likely worth filing before you pay out of pocket.

Contractor guidance
Local contractor data shows current backlogs running 2 to 4 weeks in the Rapid City market. The intake assessment rates storm chaser risk as moderate, consistent with what typically follows a regionally significant hail event — out-of-area crews move in to fill capacity gaps when the local market tightens. Under South Dakota law (SDCL Chapter 36-18A), residential roofing contractors must hold a state license through the South Dakota Contractors Board. Before signing anything, confirm the contractor's license number, verify active general liability and workers' comp coverage, and note that any contractor offering to cover your deductible is violating state law — the contract would be void.
Permits & building code
At 3.5 inches, full roof replacement is the more likely outcome than patch repair on standard architectural shingles; plan your inspection and budget accordingly. Permits are pulled by the contractor in Rapid City, cost between $150 and $350, and a post-installation inspection is required. Class 4 impact-resistant shingles qualify for a 10–20% discount with most South Dakota insurers.
