Hail
Across 61 months of NEXRAD records, no hail-bearing storm cell has been detected within ten miles of Buena Park. That is normal for this part of California and it is the reason roof claims here are almost always wind, water or age rather than impact.
Gusts, and when they happen
Over 5 years of daily records at this location, the highest modelled gust was about 45 mph, below the 58 mph severe threshold but well into the range that finds anything already lifted or loose. There were 7 days above 39 mph and 1 above 45 mph in that period, concentrated in February, April, and October.
| Date | Peak gust |
|---|---|
| 18 February 2026 | 39 mph |
| 25 February 2023 | 45 mph |
| 12 April 2022 | 39 mph |
| 14 December 2021 | 44 mph |
| 11 October 2021 | 42 mph |
What to look at after a storm
What landed on it
A branch across the roof does damage twice: once on impact and once by sitting there holding water against the covering. Get it off, photograph where it was, and look at what is underneath before deciding it was nothing.
Flashing, chimneys and skylights
Penetrations are where a roof is joined rather than laid, and joins fail first. After a wind event they are the first thing worth having looked at properly.
The ridge and the edges
Wind does not lift a roof from the middle. It gets under an edge — the rake, the eave, the ridge cap — and peels inward from there. Those are the places to look at from the ground with binoculars after a wind event, and they are the places a marginal roof gives up first.
Granules where they should not be
Look in the splash blocks and at the base of the downspouts. Granule loss concentrated in one area, rather than spread evenly, is the pattern that points at impact rather than at age.
What the street is doing
Neighbourhoods built at once wear out at once, so a run of work on one street is often a cohort reaching its age rather than a storm. Both are worth knowing about; they are not the same thing.
About this data
Hail detections come from NOAA NCEI’s Severe Weather Data Inventory (NEXRAD product nx3hail) within 10 miles of Buena Park. Radar sizes hail in a storm cell; it does not observe what landed on any particular roof. Gust figures are daily maxima from the ERA5 reanalysis archive at this city’s coordinates, which is a model of the weather rather than a reading from an instrument in the neighbourhood. Both are useful for dates and for scale, and neither is evidence about your roof. Last refreshed 2026-08-31.
Storm damage questions
There was a storm near me. Do I have damage?
A recorded storm nearby is a reason to have the roof looked at, not evidence that anything happened to it. The useful first check costs nothing: dents in the soft metal around the roof, and a look in the attic on a bright day.
