Hail reports by month, 2014 to 2024
Most hail reports in Bloomington’s county fall in May. NOAA counts county reports over eleven years; one storm can produce many.
What this means for your roof
- Hail is less frequent here than in most covered cities (18 days with hail of 1 inch or larger), so age usually matters more than storm count. A hail day still justifies an inspection.
- Freeze-thaw cycles are high here. Water that gets under flashing or shingle edges freezes and widens gaps, so ask the inspector to check flashing, valleys and eaves.
- Material ranges in the calculator are general planning figures. Your shingle manufacturer’s warranty and an in-person inspection decide when a roof needs replacing.
