Rapid City, SD experienced 2-inch golf ball-sized hail on June 4, 2026.

Damage assessment

Golf ball-sized hail at 2 inches represents a significant threat to architectural asphalt shingles, the dominant roofing material in Rapid City. This magnitude typically causes functional damage including granule loss, exposed mat, and potential cracking on shingles older than 10-15 years. Newer roofs may experience primarily cosmetic damage, though impact marks and accelerated aging are likely. Class 4 impact-resistant shingles would show substantially better performance at this hail size.

Historical context

This event ranks #124 out of 827 recorded hail events in Pennington County over the past decade. The largest recorded event reached 4.5 inches on August 26, 2021. June historically sees above-average hail activity with 266 events in 10 years, though July remains the peak month with 381 events.

Storm system

The storm system also produced 1.75-inch hail in Campbell, Wyoming, indicating a broader regional weather pattern affecting the Black Hills area.

Contractor guidance

Rapid City's moderate contractor market currently shows 2-4 week backlogs, with moderate storm chaser risk following regional events. South Dakota SB 145, codified in SDCL Chapter 36-18A, prohibits contractors from advertising deductible waivers and provides 72-hour contract cancellation rights. All residential roofing contractors must hold licenses through the South Dakota Contractors Board under SDCL Chapter 36-18A. Verify contractor licensing status 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 roofs. Contractors must pull permits costing $150-350, and inspections are required. Given the 10-20% insurance discount for Class 4 shingles and their superior hail resistance, homeowners should consider upgrading during repairs.
