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 Report Description: An F1 tornado touched down along the Lower Merion Township side of the Narberth Borough/Lower Merion Township line. The tornado then proceeded east into Narberth Borough and remained on the ground for three-quarters of a mile. Wind damage was mainly whole trees and wires that were knocked down. More than 100 whole trees were knocked down. Dozens of homes were damaged by fallen trees. One tree fell through one house in Narbrook Park. The parent thunderstorm produced straight line wind damage in Delaware County and southwestern parts of Lower Merion Township before the tornado formed near North Wynnewood Avenue.

Tornado Report Description: A severe thunderstorm caused wind damage in downtown Norristown. As the storm was exiting Norristown, it dropped a tornado (F1 estimated winds 80 mph) between High and Tremont Streets. The tornado proceeded east into Plymouth Township and lifted around the Plymouth Country Club. Nevertheless, damaging wind gusts associated with the severe thunderstorm continued along a east path until the Germantown Pike. The worst damage in Norristown was inflicted upon the Curren Terrace Apartment Complex as a piece of the roof was removed. Two dozen residents of the complex were evacuated from the damaged building. Several other houses, mainly in Norristown, had structural damage to their roofs and chimneys. Two were rendered structurally unsound. The remaining damage was inflicted upon trees which were sheared and toppled. Streets which reported the most damage included DeKalb, Elm and Hamilton in Norristown and Graves, Nursery Drive Sandy Hill, Thomas and Walnut Lane in Plymouth. No injuries were reported. The severe thunderstorms throughout Montgomery County caused 17,000 homes to lose electricity.

Tornado Report Description: ,,,,,,,,Lightning A F1 (Fujita Scale) tornado touched down in the Brandywine Village/Lafayette Park area of Upper Merion Township on Allendale Road just to the north of the Pennsylvania Turnpike (Interstate 276). The tornado sighting was phoned into the National Weather Service by a SKYWARN Spotter. The tornado stayed on the ground for about one mile before lifting around Crossfield Road. Most of the wind damage was downed or snapped (40 to 50) trees. The bulk of the uprooted trees were either in poor health or very old. Two houses were damaged by trees falling on them. The worse one sustained about $6,000 in damage to its roof, porch, upstairs bathroom and gutters. The tornado touched down within one mile of the King of Prussia Mall. No injuries were reported. This was the 12th confirmed tornado in the Greater Philadelphia Metropolitan Area this year. Elsewhere in Montgomery County damaging winds knocked over a centerfield fence and uprooted between 12 and 18 trees in Upper Gwynedd Township. A lightning strike ignited a fire in an Upper Gwynedd house. It apparently entered through the electrical box and started a fire in the basement. Damage was estimated between $25,000 and $30,000. Thunderstorm winds uprooted a large pear tree in Audubon. Frequent lightning resulted in power outages to 55,000 Philadelphia Electric Company (PECO) customers throughout their service area.

Tornado Report Description: The parent thunderstorm that produced two tornadoes and downburst wind damage in eastern Chester County split in two near Spring City in Chester County. The left or western thunderstorm entered Montgomery County in Royersford and wind related damage intensified as the thunderstorm moved northeast through Royersford. Most of the damage (collapsed porches and downed trees) in Royerstown occurred from Fifth Avenue to Lewis Road and from Main to Chestnut Streets Several homes were damaged by falling trees. Lewis Road was closed for two days because of tree removal. From police and eyewitness reports apparently a funnel cloud was working its way toward the ground over Royersford and became a tornado in Limerick just to the northeast of Linfield Road at 10:45 pm EST. The tornado intensified into a strong (F3 on the Fujita Scale) one as it paralleled Limerick Road on its western side. A development called "The Hamlet" was in the direct path of this tornado. The Hamlet was a new development started within the past 2 years and about 30 of the planned 430 units were occupied or under construction. The development took a direct hit from the tornado. This resulted in 3 deaths (the same family) and 25 injuries. Of the 27 inhabited houses, 4 were leveled, 16 were damaged beyond repair, 1 under construction was destroyed and only 7 remained liveable. Damage in this development alone was $2 million. The family of three which lost their lives lived on Victory Way. They were asleep and blown out of their house. The father was found on the front lawn. The mother and her 10-month-old daughter were found over a sewer grate. A United States Savings Bond in the child's name was found the next day in Bath, Pennsylvania. Bath is located about 50 miles northeast in Northampton County. Another man was blown through the second story window of his house about 50 feet into the family room of his neighbor's house and survived. Equally miraculous a 5-month-old infant sailed out of his crib onto the front lawn of his home and survived. As tragic as the devastation was at "The Hamlet", it was not the only place in Limerick to sustain damage. As the tornado traveled through the business area of the town, it leveled most of the Hide and Seek Storage Sheds (damage estimated at $1 million). It peeled part of the roof off the Limerick Diner. None of the 30 patrons inside were injured. The Atlantic and Sunoco Gas Stations sustained major damage. Gasoline pumps at the Sunoco Station were wrenched from their cement foundation. An overturned beige truck lay about 200 yards from where it was parked. Even the Limerick Fire House sustained about $25,000 in wind damage. In addition to "The Hamlet", 14 other homes in Limerick sustained major damage. About 90 persons in Limerick had to find temporary shelter. Total damage in Limerick alone was estimated between $5 and $5.5 million. The tornado lifted in the Limerick Garden of Memories Cemetery, but its parent thunderstorm continued to produce wind related damage in upper (northwestern) Montgomery County. Downed trees were reported in Zieglersville. In Marlboro Township about 50 to 60 trees were uprooted on Swamp Creek and Miller Roads. About 10 properties were damaged by the falling trees, including one house that had six trees on top of it. A lightning ignited fire extensively damaged a West Marlborough home. It took six fire companies to get it under control. (M28P), (F28P), (F1P)

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.
