Hail and wind recorded near Placentia
This page is the recorded storm history for Placentia, not a general article about hail. Radar detections on two days in the last five years, on 19 March 2024 and 5 October 2021.
What is going on with the roof?
No cost to you. Contractors pay us, you do not.
Your request is in.
We are matching it now against roofing contractors working in Placentia and the surrounding area.
- Today, usually within the hour. The first contractor calls or texts the number you gave us. ASAP requests go out first.
- Up to three of them, no more. We cap it at three so you can compare without your phone melting.
- They come and look. Estimates are given after somebody has been on the roof, not over the phone.
- You decide, or you do not. There is nothing to cancel and nothing to pay us.
If you do not hear anything today, check your voicemail and spam folder — contractors often call from a mobile number.
The hail record
The most recent detection was on 19 March 2024, about 2 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 4.1 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 |
|---|---|---|---|
| 19 March 2024 | 0.5 in | 4.1 mi | 7 |
| 5 October 2021 | 0.5 in | 9.7 mi | 1 |
The wind record
Over 5 years of daily records at this location, the highest modelled gust was about 47 mph, below the 58 mph severe threshold but well into the range that finds anything already lifted or loose. There were 5 days above 39 mph and 1 above 45 mph in that period, concentrated in February, August, and November.
| Date | Peak gust |
|---|---|
| 18 February 2026 | 39 mph |
| 6 November 2024 | 47 mph |
| 20 August 2023 | 39 mph |
| 25 February 2023 | 43 mph |
| 14 December 2021 | 44 mph |
What to look at after a storm
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.
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.
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.
Granules where they should not be
A cupful of granules at the bottom of a downspout after a storm is not proof of impact — roofs shed granules as they age — but a sudden change is worth photographing with the date on it. What matters is the difference from last month, which is why photographing a sound roof now is not a wasted hour.
What landed on it
Wind-blown debris is the cause of a surprising share of storm claims, and it is the one kind of damage that is genuinely obvious once somebody looks.
The claim window
The reporting deadline in a policy runs from the date of the loss. Damage found late is denied on that basis more often than on any argument about the damage itself, and the dates above exist precisely so that a date is available when one is needed.
None of which means filing on every storm. It means knowing the date, having the damage looked at, and then deciding — in that order.

Where these numbers come from
Hail detections come from NOAA NCEI’s Severe Weather Data Inventory (NEXRAD product nx3hail) within 10 miles of Placentia. 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.
Questions after a storm
Where do the storm dates on this site come from?
Hail comes from NOAA’s Severe Weather Data Inventory — radar detections of hail-bearing storm cells within ten miles of Placentia, with an estimated stone size. Wind comes from the ERA5 reanalysis archive as a daily maximum gust at this city’s coordinates. Both are useful for dates and scale. Neither is an observation of your roof, and we do not present them as one.
There was a storm near me. Do I have damage?
There is no way to know from the weather record, and this site does not claim otherwise. Two houses on one street come out of the same night in completely different condition. What a nearby storm gives you is a date and a reason to look — starting with the gutters and vent caps, which dent before shingles mark.
How long do I have to report storm damage?
Your policy sets the limit and it is measured from the loss, not from the discovery. Reporting is not the same as committing to a claim, so if there is any doubt it is usually better to report and then decide.
