Hail damage roof Rapid City, SD

Western South Dakota’s hail season is short and fierce, and the Black Hills help spin up storms that drop big stones fast. 2026 was a busy year around Rapid City. Golf ball hail fell in town on June 22. Then on August 11, a long-lived supercell formed over the northern Black Hills and tracked southeast past Johnson Siding, Rockerville, Hayward, and Hermosa, dropping hail up to 3.6 inches, with some spots getting pounded for 10 to 15 minutes.

If you live in Rapid City or the surrounding hills, here’s what was reported and what to do next.

2026 hail around Rapid City at a glance

Storm reports are preliminary point observations from spotters, chasers, the public, and NWS staff. Hail varies sharply over short distances in the hills. Use these as a starting point, not proof about your own roof.

August 11: the Rockerville–Hermosa hailstorm

NWS Rapid City’s event summary describes a “long-track thunderstorm, and prolific and destructive hail producer” that formed just after 1 p.m. MDT in the northern Black Hills. It first produced quarter to tennis ball size hail from near Nemo to Johnson Siding to Rockerville, where “hail covered the ground and resulted in numerous broken windshields.”

As it continued southeast, the Hayward-to-Hermosa corridor saw “numerous reports of baseball (2.75” diameter) and larger sized hail.” The largest measurement was 3.6 inches, 2 miles south-southwest of Hermosa. NWS notes the hail “fell for 10-15 minutes in some areas,” with shattered home and vehicle windows, dented vehicles, broken downspouts and gutters, and a destroyed carport. One SPC report near Hermosa mentions three broken skylights. NWS’s photo gallery includes hail damage to a building roof in Hayward.

The same storm went on to produce 4-inch hail near Oglala and Pine Ridge, where NWS reports roofs damaged and widespread, catastrophic damage to homes and vehicles.

June 22: golf ball hail in town

On the late afternoon of June 22, NOAA’s Storm Events Database records trained spotter reports of 1.75-inch hail in Rapid City, and notes that supercells “produced severe hail across much of Pennington County including at the NWS office.” Ping pong ball hail covered the ground more than an inch deep near Nemo, according to SPC reports.

What this means for Rapid City-area roofs

Long-duration hail does more damage. Ten to fifteen minutes of large hail is very different from a 60-second burst. Homes along Highway 16 and Highway 79, Rockerville, Hart Ranch, Hayward, and Hermosa should get a close inspection even if the roof looks okay from the ground.

Check skylights, vents, and gutters. Broken skylights and dented metal are quick clues that the shingles took hits too.

More than one storm. If you were hit in June and again in August, note the dates. Insurers generally handle separate storms as separate claims, often with separate deductibles.

The building season is short. With winter coming, it’s worth getting inspections and claims moving now. If a roof is leaking, a tarp and receipts for temporary repairs are reasonable steps most policies expect.

Rapid City rules worth knowing

Verified from the City of Rapid City. General information, not legal advice.

• Roofers need a city license. Rapid City requires a city license for roofing contractors (Class R) and requires licensees to carry liability insurance (Rapid City Municipal Code 15.04.140). In a 2020 advisory, the city warned homeowners that some out-of-town crews point to a “state license,” but South Dakota only issues an excise tax license, so ask for the Rapid City license.
• Permits are required for roofing work. The city’s Building Services Division (605-394-4120) can tell you what your job needs.
• Re-roofs mean tear-off. Rapid City’s amended code generally requires removing all existing roof layers down to bare wood before installing new shingles, with limited exceptions (RCMC 15.13.280). A quote that layers new shingles over old ones should raise questions.
• Code items. The city advises making sure roofing work includes code-related items such as ice shield and flashings, and checking whether your policy covers code upgrades.
• Outside city limits (Rockerville, Hermosa, Hayward), rules depend on your county or town. Check locally.

What to do this week

1. Note your storm date(s) and save the NWS event page and SPC reports linked below.
2. Photograph damage from the ground: skylights, gutters, downspouts, vents, siding, windows, vehicles.
3. Find your deductible and how your roof is covered (replacement cost or actual cash value). See our deductibles guide.
4. Get an inspection from a Rapid City-licensed roofer (or one properly licensed where you live). Ask for the license and proof of insurance. Don’t sign on the doorstep.
5. File promptly if there’s real damage. Our claim guide has the steps.
6. Compare bids. Post your job so roofers compete, and check any quote before you sign.

What will it cost?

Price depends on roof size, pitch, material, tear-off, and local labor, and post-storm demand can push prices around. We won’t invent a Rapid City figure. Start with our free roof cost estimator, and see how South Dakota compares in our roof replacement cost by state guide. Because Rapid City requires full tear-off on re-roofs, make sure every quote you compare includes it.
