Does this mean roofs in the area 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. This tells you where it is worth looking.

How accurate is this hail map?

Sizes come from NOAA MRMS radar (MESH), which runs about ±0.25 inches against ground truth and resolves to roughly 1 km cells. That makes it canvass-targeting quality — good enough to pick the neighbourhoods worth knocking, not a substitute for claim evidence.

NOAA's Probability of Severe Hail peaked at 30% over Sun Prairie that day — low to moderate: the radar signature was there, ground impact less certain. It is a separate model from the size estimate above: one asks how big the stones were in the storm, the other asks whether they made it down.
