What best describes your home?

Different buildings need different crews, so this is the first thing a roofer asks.

No cost to you. Contractors pay us, you do not.

Hail

Across 61 months of NEXRAD records, no hail-bearing storm cell has been detected within ten miles of Cypress. 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.

Wind

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.

What to check afterwards

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.

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.

Inside, before outside

The underside of the deck is the most honest surface on the whole house. It shows water that has not yet reached a ceiling, and it tells you roughly how long the water has been arriving.

The ridge and the edges

Ridge caps sitting proud, a line of shingles along the rake that no longer lies flat, a lifted starter course at the eave: these are wind signatures, and each one is an opening for the next storm rather than a cosmetic complaint.

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.

Reporting, and the clock on it

Every policy sets a period within which a loss has to be reported, measured from the event rather than from the discovery. That is the practical reason a dated record of local storms is useful to a homeowner at all.

Reporting is not the same as committing. A claim that turns out to be below the deductible can be withdrawn, and finding out the scale of the damage before filing is generally the right order.

The full guide to how a roof claim works

Sources, and what they can and cannot tell you

Hail detections come from NOAA NCEI’s Severe Weather Data Inventory (NEXRAD product nx3hail) within 10 miles of Cypress. 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.

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 Cypress, 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.

How long do I have to report storm damage?

Less time than most people assume, and the clock runs from the date of the event rather than from the day you noticed. Policies require prompt notice and set an outer limit on reporting. That is the single most common reason late-discovered damage is denied, and it is why knowing the date of the storm matters.
