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 Report Description: Storm door on garage was removed from its frame. Lots of tree branches down_ including some large.

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.

Not necessarily. A storm report only means hail, wind, or a tornado was observed nearby; it does not confirm damage at any specific address, and conditions change from block to block.

I am buying a home in Clinton County — why should I look at its storm history?
