Olathe hail history
Radar-detected hail days over Olathe, most recent first. If your roof was on the house for any of these and nobody has been up there since, the inspection is free.
Olathe is one of the most hail-exposed cities in the United States. NOAA radar records show 193 hail days over the city since 2014, and 2026 alone has produced eighteen of them. The largest stone on record over Olathe measured 3½ inches, on June 27, 2016.
The table below is the recent record. It is worth knowing which of these crossed your address, because a hail claim is far easier to make when the damage can be tied to a specific dated storm — and far harder once two or three seasons have blurred together.

Source: hail days detected over Olathe, Kansas by NOAA's MRMS radar system. "Max hail" is the largest reported stone size for that day over the city; hail falls in narrow swaths, so your street may have seen more or less than the figure shown.
Reading the sizes
- 1 inch (quarter). Marks soft metals — gutters, vents, fascia wrap. Starts bruising older or brittle shingles. Worth an inspection on a roof over twelve years old.
- 1½ inch (walnut). Bruises most asphalt shingles. Commonly claim-level damage.
- 1¾–2 inch (golf ball). Widespread bruising and granule loss on nearly any asphalt roof.
- 2½ inch (tennis ball). A standard shingle roof is usually a total loss. Cracked skylights, punctured vents, badly dented gutters.
- 2¾ inch and up (baseball). Structural damage to roof coverings, siding, windows and vehicles.
What to do if one of these hit your street
Get the roof looked at before the link to the storm gets harder to argue. Our hail inspection is free, it uses the same chalked test-square method your adjuster will use, and the written report is dated to the storm it matches. If there is no claim, we will tell you that too — and you will have a dated baseline for the next one, which in this city is usually weeks away rather than years.
