Hail damage in Birmingham, AL
Radar has detected hail over Birmingham on 302 separate days since 2016. On 76 of them the largest stone was estimated at golf-ball size or bigger. The biggest was 8.9 cm on May 10, 2024.
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 | 57 / 100 | × 0.35 | 19.9 |
| Severity Largest stone radar estimated in the whole window | 85 / 100 | × 0.30 | 25.4 |
| Recency How long since the last 2 in (5 cm) day | 92 / 100 | × 0.20 | 18.3 |
| Concentration Hail days per year reaching golf-ball size | 38 / 100 | × 0.15 | 5.7 |
| RoofTake Score | 69 | ||
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.
Alabama hail claims cluster in March and April, ahead of the plains season.

"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 45 hail days.
Hail days by month
Peak month: July. Hail season in Alabama 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 Birmingham
- 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 Birmingham radar record and the NOAA citation into your notice of claim.

Hail in Birmingham, AL: common questions
How often does Birmingham get damaging hail?
Radar recorded 302 hail days within 25 miles of the city centre between 2016 and 2025 — an average of 30.2 a year, of which 7.6 a year were at golf-ball size or larger. Not every one of those damages roofs.
When is hail season in Birmingham?
The busiest month in this record is July, and 2023 was the busiest single year with 45 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.
