Golf ball-sized hail detected near Rochester, MN on September 2, 2026
Hail was detected at a radar-indicated point within the Rochester 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 point was approximately 8 miles south of downtown Rochester, with one hail report logged in Olmsted County that day. At 1.75 inches, architectural asphalt shingles face a real risk of functional damage — granule loss is likely, and shingles older than 10–15 years can sustain cracking or bruising that compromises the mat beneath. Newer shingles may show cosmetic damage only, but age and pre-existing wear change that calculus quickly. The county's largest recorded event hit 3 inches in July 2023, so this storm is mid-range by regional standards.
On a $287,500 home with a 2% deductible, the threshold to clear is $5,750. Typical repair cost for a 2,000 square foot roof runs $8,568, with a range of $7,010 to $10,126 depending on material condition 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 of 2 to 4 weeks in the Rochester market — not severe, but enough that scheduling early matters. The intake assessment rates storm chaser risk as moderate, with out-of-area contractors known to move in after regional events. Minnesota requires roofing contractors to register with the Department of Labor and Industry as a residential contractor under Minn. Stat. § 326B.092, which mandates proof of general liability and workers' comp. Before signing anything, verify the contractor's registration through the MN Department of Labor and Industry's online license lookup.
Permits & building code
At 1.75 inches, repair is possible on newer roofs, but replacement becomes the likely outcome on anything with significant age or prior damage. Permits in Rochester run $150 to $350, are pulled by the contractor, and require inspection upon completion. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Minnesota insurers.
