Hail damage in Columbia, MO
Radar has detected hail over Columbia on 247 separate days since 2016. On 52 of them the largest stone was estimated at golf-ball size or bigger. The biggest was 10.2 cm on July 19, 2023.
A high value in this historical exposure model. Radar estimates do not establish what reached a property or whether it was damaged.
How we got to that number
| Component | Value | Weight | Contribution |
|---|---|---|---|
| Frequency Hail days per year at 1.00 in (2.5 cm) or larger | 42 / 100 | × 0.35 | 14.9 |
| Severity Largest stone radar estimated in the whole window | 100 / 100 | × 0.30 | 30.0 |
| Recency How long since the last 2 in (5 cm) day | 97 / 100 | × 0.20 | 19.5 |
| Concentration Hail days per year reaching golf-ball size | 26 / 100 | × 0.15 | 3.9 |
| RoofTake Score | 68 | ||
The score describes an area, not a house. Two roofs on the same street of different ages face very different risk from the identical storm. The whole formula and its weights are on the methodology page, and you can recompute it yourself from our public data.
Mid-Missouri sits on the boundary where plains storms weaken and re-fire.

"Signatures" is the number of separate radar volume scans that detected hail in a storm cell within 25 miles that day. More signatures means a longer-lived or larger storm, not necessarily bigger stones.
Hail days by year
Busiest year in the record: 2023 with 36 hail days.
Hail days by month
Peak month: June. Hail season in Missouri is short and it is not distributed evenly — most of the annual risk arrives in a few weeks.
What to do with this if you own a roof in Columbia
- Find your dates. Look up your ZIP for the record nearest you, and note every day at 1.00 in or above since you bought the house.
- Work out whether your roof could have survived them. A twelve-year-old asphalt roof and a two-year-old one respond very differently to the same stone — the age calculator explains why.
- Look, before you file. Nine photographs, none of them requiring you to get on the roof.
- Check the arithmetic. If the actual cash value of the damage is under your deductible, filing pays nothing — work it out first.
- Then write. The letter generator puts the Columbia radar record and the NOAA citation into your notice of claim.

Hail in Columbia, MO: common questions
How often does Columbia get damaging hail?
Radar recorded 247 hail days within 25 miles of the city centre between 2016 and 2025 — an average of 24.7 a year, of which 5.2 a year were at golf-ball size or larger. Not every one of those damages roofs.
When is hail season in Columbia?
The busiest month in this record is June, and 2023 was the busiest single year with 36 hail days.
Does this mean my roof is damaged?
No. These are radar estimates of the largest stone aloft in a storm cell somewhere within 25 miles of the city centre. Whether anything landed on your street, and whether it damaged your particular roof, needs somebody to look.
How do I use this for an insurance claim?
A specific date with a public, citable source is what turns 'sometime last year' into a date of loss. Use the claim letter generator, which pulls the date and the NOAA citation in for you.
Why 25 miles?
It is wide enough to catch storms that clipped the metro and narrow enough that the number still means something for a house inside it. The same radius is used for every metro so the pages are comparable.
