What this record means for a Good Thunder roof

The list above covers 24 radar-confirmed hail days over Good Thunder between 2011 and 2026. The largest signature recorded over the Good Thunder area was 4" (baseball size or larger) on June 2, 2020. Radar put the local estimate at or above the 1" mark, the size generally capable of damaging asphalt shingles, on every one of those days.

Insurers and their adjusters can pull this same NOAA archive, so a date on this list is not news to the company handling a claim. What the archive cannot show is the condition of your specific roof, which is why dated photos and a written inspection report carry the weight in a dispute. Most homeowner policies also set a deadline to report storm damage, commonly one or two years from the date of loss, so a recent date above matters most if the roof was never inspected after it.

Radar cannot confirm what hit your shingles; an inspection can, and it costs you nothing. For Minnesota properties, our sister site MN Hail Buddy passes your request to exactly one licensed Minnesota contractor: one company, never a blast list, and your information is not sold to anyone else.

Common questions

Has Good Thunder had hail big enough to damage roofs?

Radar has detected hail up to 4" (baseball size or larger) over the Good Thunder area, most recently on July 2, 2026. Hail of 1" or larger is generally considered capable of damaging asphalt shingles.

Does this prove my roof was damaged?

No. Radar estimates hail aloft, accurate to roughly a mile, and cannot confirm what reached any specific roof. It is a strong reason to document your roof and check your policy's claim deadline after a listed date, not proof of damage.
