Hail Damage Risk for Your Home +

Hail reports describe hail by diameter, often comparing stone size to familiar objects like peas, quarters, golf balls, and softballs. Use this guide as a starting point for possible hail damage to your roof, siding, gutters, vents, windows, and exterior. Actual hail damage depends on hail hardness, density, wind speed, impact angle, roof age, shingle condition, roof pitch, roofing material, installation quality, and prior storm damage.

Pea

0.25″

Low

Usually too small to cause hail damage to most sound asphalt roofs, siding, or gutters.

Mothball

0.50″

Sub-Severe Watch

Below the NWS severe-hail threshold, but not always harmless. Repeated small hail can scuff surfaces, wear aging shingles, and loosen protective granules over time.

Penny

0.75″

Minor / Watch

Below the NWS severe-hail threshold, but roof hail damage is still possible on older, brittle, poorly installed, or previously damaged shingles. May also mark screens, vents, gutters, and soft metal.

Nickel

0.88″

Minor / Watch

Still below the severe-hail threshold, but large enough to leave visible marks on soft metal and add wear to older or hail-weakened roof shingles.

Quarter

1.00″

Watch

The NWS severe-hail threshold. Quarter-size hail can bruise shingles, dent soft metal, and create roof hail damage worth checking.

Half Dollar

1.25″

Watch

More likely to dent gutters, vents, flashing, and siding. Hail damage risk rises quickly on older roofs or hail-weakened shingles.

Ping Pong / Walnut

1.50″

Likely

Hail damage becomes more likely, including bruised shingles, granule loss, dented siding, and damaged roof vents.

Golf Ball

1.75″

Likely

Often causes roof hail damage, cracked shingles, dented gutters, damaged flashing, and siding impacts. A roof inspection is recommended.

Hen Egg

2.00″

Serious

Can crack or puncture shingles, expose mat, dent siding, and cause widespread hail damage across the roof and exterior.

Tennis Ball

2.50″

Serious

Can cause heavy roof hail damage, punctured siding, broken skylights, damaged vents, and widespread exterior damage.

Baseball

2.75″

Major

Major hail damage is likely, including severe roof impacts, damaged siding, broken windows, and possible major roof repairs.

Tea Cup / Large Apple

3.00″

Major

Can cause heavy hail damage across the roof, siding, gutters, windows, and exterior. Significant repairs are often needed.

Softball

4.00″

Extreme

Destructive hail damage. Can severely damage roofing materials, siding, windows, gutters, vents, vehicles, and exterior surfaces.

Grapefruit

4.50″

Extreme

Catastrophic hail damage risk for roofs, windows, vehicles, siding, gutters, and exterior surfaces.

Source: NOAA / National Weather Service hail size references are used for hail-size comparisons and the 1.00″ severe-hail threshold. Damage descriptions are general homeowner guidance, not official NOAA/NWS damage ratings. Sub-severe hail under 1.00″ is below the severe threshold, but that does not mean “no roof damage.” Penny- to nickel-size hail can still contribute to granule loss, cosmetic surface marks, and added wear, especially on older, brittle, poorly installed, or previously damaged roofs.

Wind Damage Risk for Your Home +

Storm reports list thunderstorm wind gusts in mph. The NWS marks storms as severe at 58+ mph, but wind damage to your home depends on roof age, shingle condition, installation, exposure, nearby trees, and prior hail or wind damage.

Below Severe

Under 58 mph

Minor

Usually little damage to a sound roof, but loose shingles, flashing, or debris may shift.

Severe

58–74 mph

Watch

Can loosen shingles, lift flashing, break limbs, and damage gutters, siding, fences, or trim.

Damaging

75–90 mph

Serious

Can peel shingles, damage vents, tear siding, rip gutters, and expose weak roof areas.

Extreme

90+ mph

Major

Can cause major roof covering loss, tree damage, broken windows, and structural damage.

Source: NOAA / National Weather Service storm reports. Gusts may be measured or estimated; actual wind damage varies by roof condition, exposure, and prior hail or wind damage.

Tornado Damage Risk for Your Home +

After a tornado, the National Weather Service assigns an EF rating from EF0 to EF5 based on surveyed damage. The rating estimates wind speed from what the tornado damaged, so actual damage can vary by construction quality, roof age, garage doors, windows, trees, debris, and how close the home was to the tornado path.

EF0

65–85 mph

Light

Can peel shingles, damage gutters or siding, break tree limbs, and toss loose outdoor items.

EF1

86–110 mph

Moderate

Can strip roof covering, damage exterior doors, break windows, snap trees, and cause heavier siding or gutter damage.

EF2

111–135 mph

Serious

Can tear off large sections of roofing, break or uproot trees, destroy weaker structures, and cause major exterior damage.

EF3–EF5

136+ mph

Severe

Can remove roofs and walls, destroy large portions of homes, toss vehicles, and cause severe to total destruction near the path.

Source: NOAA / National Weather Service. EF ratings are assigned after a post-storm damage survey and are based on observed damage, not a direct measurement at every home.

Frequently asked questions

for homeowners, buyers & sellers

How many storm reports were recorded on May 21, 1999?

Our records show 62 hail, 15 wind, and 1 tornado reports on May 21, 1999, compiled from NOAA SPC and NWS Local Storm Reports. The most recent was reported on May 21, 1999.

What was the largest hail reported on May 21, 1999?

The largest hail size in these storm-report records on May 21, 1999 is 1.75″, reported near Beach, ND.

Some reports show UNK instead of a wind speed or tornado rating — what does that mean?

Wind reports come three ways: measured from an instrument, estimated from the damage observed, or UNK when no speed was recorded. Tornadoes show UNK until the National Weather Service finishes a damage survey and assigns an EF rating. UNK simply means that value was not available when the report was filed.

A report appeared near my home on May 21, 1999 — is my roof damaged?

Not necessarily. A storm report shows that hail, wind, or a tornado was observed nearby, not that any specific home was hit. To find out whether your property was affected, check an address-level hail report, and if it looks significant, ask a local pro about a Remote Hail Inspection before scheduling roof work.

I am buying or selling a home — how do these on May 21, 1999 reports help?

If a storm passed through, a roof or exterior may have damage that is hard to see, or a recent repair may trace back to it. Buyers can ask better questions before closing, and sellers can document the home condition up front — both starting from the property address rather than a whole region.

How do I check what happened at a specific address on May 21, 1999?

Use the address search to pull a free address-level hail report for any property — no phone number or email required. It shows recent hail activity for that address so you know whether a closer roof or exterior review makes sense.

Where does this storm report data come from, and what are its limits?

Storm reports on this page are public reports from storm events on May 21, 1999 across the United States, sourced from NOAA SPC and NWS Local Storm Reports. They show where hail, wind, or tornado activity was reported, but they do not confirm damage at any specific property. Report locations, sizes, and times may be approximate and can vary from what an individual home experienced. For property-specific hail history, use an address-level hail report or contact a participating local professional for a remote hail inspection. Pros inclusion is not an endorsement, and contacting a professional does not confirm damage at any property.
