What the radar recorded
The most recent detection was on 18 March 2024, about 3 years ago. Radar sized the largest stone in that cell at about 0.5 inches, small, and unlikely on its own to have marked a sound roof. The nearest cell was about 5.1 miles away, which is close enough to be worth checking and far enough that it may have missed the house entirely.
| Date | Largest stone sized by radar | Nearest cell | Cells that day |
|---|---|---|---|
| 18 March 2024 | 0.5 in | 5.1 mi | 4 |
| 3 September 2022 | 1.0 in | 9 mi | 3 |
| 5 October 2021 | 1.0 in | 1.7 mi | 4 |
The wind record
Over 5 years of daily records at this location, the highest modelled gust was about 56 mph, below the 58 mph severe threshold but well into the range that finds anything already lifted or loose. There were 18 days above 39 mph and 3 above 45 mph in that period, concentrated in January, February, and March.
| Date | Peak gust |
|---|---|
| 16 February 2026 | 44 mph |
| 8 January 2025 | 46 mph |
| 14 March 2024 | 56 mph |
| 21 March 2023 | 43 mph |
| 25 February 2023 | 50 mph |
| 23 January 2023 | 43 mph |
| 2 February 2022 | 43 mph |

What to look at after a storm
What the street is doing
If several roofs on the street are being worked on and yours is the same age and the same covering, that is a reason to have yours looked at. It is not a reason to assume you have damage, and a contractor who tells you the whole street is getting a new roof paid for by insurance is telling you something about themselves.
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.
Inside, before outside
Go into the attic on a bright day with the lights off. Daylight through the deck, fresh staining on the sheathing, or a rust track down a nail shank all say water got in. The attic shows it long before a ceiling does, and dated photographs of it are worth a great deal later.
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.
The soft metal, first
Gutters, downspouts, vent caps, and any aluminium fascia are softer than the roof covering and dent before it marks. If there are no dents in the soft metal, there is very probably no impact damage on the shingles either. This is the check an inspector makes before getting on the roof, and you can make it from the ground.
About this data
Hail detections come from NOAA NCEI’s Severe Weather Data Inventory (NEXRAD product nx3hail) within 10 miles of Mission Viejo. 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.
Commonly asked
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.
