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.

Tornado Report Description: A NWS storm survey team found evidence that a small EF1 tornado touched down just south of Brockton in Walker Township at 1837 EDT. The tornado traveled only about a quarter of a mile to the east-northeast, before dissipating near Kettle Road around 1838 EDT. The tornado was embedded in a larger area of downburst winds, which extended approximately two miles farther to the east, crossing Catawissa Road.||Damage caused by the tornado was mainly confined to a wooded area, snapping or toppling about 25 trees. The tornado appeared to dissipate on the property along Kettle Road. Here, a large awning/roof was removed from a home. A barn was completely leveled. Across Kettle Road, another home lost portions of it's roof from the wind. Moderate damage to the house was also sustained from flying debris from the collapsed barn across the road. The downburst winds next encountered a home and several barns along Catawissa Road over a mile to the east. Significant roofing loss was noted at two barns on the west side of Catawissa Road, and one on the east side of Catawissa Road. This marked the end of the concentrated downburst damage path.||The tornado and downburst winds both had damage indicators implying peak winds around 95 mph. The tornado was rated an EF1. There were no injuries or fatalities.

Northumberland County · 26,911 Homes in County
Tornado Report Description: The NWS State College confirmed a EF1 tornado in Northumberland County. The tornado touched down around 1739 EDT near Winfield in Union County and traveled east across the Susquehanna River approximately 1 1/4 miles between 1740-1741 EDT before lifting near PA 147 around 1742 EDT. The tornado first touched down west of 165 Grover Road in Union County. Damage was primarily snapped and uprooted trees. The tornado moved down the hill crossing US-15 and River Breeze Avenue before moving over the Susquehanna River into Northumberland County. Tree damage along River Breeze road caused damage to two homes, and trees were snapped on the south end of an island near the east shore of the river. The tornado moved through a campground north of Ferry Road, downing and uprooting trees in the camp ground. The trees damaged several camper vans and a pavilion before crossing a field and moving up the hill. Strong southerly inflow ahead of the tornado damaged five homes along Route 147. Leaves plastered to these houses implied strong southerly and easterly winds. Aluminum siding on the southern side of the several houses was dented and the winds blew out the west wall of garage of another house, which had its south facing garage doors left open during the storm. Another home closer to the river also sustained damage to the roof, chimney, and exterior walls. In this same area, utility poles were downed and snapped. Tree damage and minor damage was sustained by sustained at two homes to the north of the more heavily damaged homes. Throughout the damage swath, most trees fell from southwest to northeast, and fewer fell from the south. Several outbuildings west of Route 147, including one two-story cinder block shed, were destroyed by the tornado. Roofing debris from these outbuildings was found in adjacent properties and in an open field across Route 147. Some of this debris was also found embedded several inches into nearby trees. The tornado dissipated up the hill, perhaps 200 yards east of a power line easement. There were several eyewitnesses, and most had taken shelter. One eyewitness living near the corner of Route 147 and Ferry Road watched the wind move northward, heard the roar of the storm and watched a white cloud pass to his north over the homes. The damage indicators were consistent with peak winds around 110 mph. There were no injuries or fatalities.

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.

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 23, 2011 — 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 23, 2011 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 23, 2011?

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 23, 2011 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.
