How big was the hail on July 28, 2023?

The maximum estimated stone size anywhere in Wisconsin that day was 1.50 inches. Sizes vary street to street inside a single swath, so a city's figure is the largest radar estimated anywhere within about 5 miles of it.

Does this mean roofs were damaged?

Radar measures stone size, not damage. Whether a particular roof was damaged depends on stone size, wind direction, roof age and material — only an inspection settles it. These figures tell you where it is worth looking.
