Golf-Ball Hail in Dauphin County: What the June 2023 Storm Did to Roofs
Hail approaching golf-ball size reached parts of the county in June 2023. Roofs that looked fine that week are failing now — here is why.
The short answer
Severe storms in June 2023 brought hail approaching golf-ball size to parts of Dauphin County. Roofs that looked untouched that week are failing now, because hail bruises the mat under the surface rather than punching through — and bruised shingles age several times faster than the material around them.
Severe thunderstorms in June 2023 brought hail approaching golf-ball size to parts of Dauphin County. For most homeowners it was a loud twenty minutes, some dented gutters, and then it was over.
The roofs looked fine. That is the entire problem with hail, and it is why we are still writing about a storm from three summers ago.
Hail damage does not announce itself. It shows up years later as a roof failing well ahead of schedule, long after any claim window has closed.
What golf-ball hail does to an asphalt shingle
Roughly one-inch hail is generally where damage to asphalt shingles begins. Anything approaching golf-ball size — around 1.75 inches — will bruise almost any conventional shingle it strikes squarely.
The impact does two things. It knocks the mineral granules off the surface at the point of contact, and it fractures the fiberglass mat underneath, leaving a soft spot you can feel with a thumb.
The granules are the shingle's sunscreen. Without them, that spot is exposed asphalt sitting in direct ultraviolet light, and it ages at several times the rate of the material around it. Three to five years later, that is where the cracking starts.
Why the roof looked fine afterward
- Bruising is not visible from the ground. It is a subtle dark circle, and you have to be on the roof and pressing on it to identify it
- Nothing leaks immediately. The shingle is still shedding water; what it has lost is service life
- Granule loss looks like normal weathering to anyone who is not comparing it to the sheltered parts of the same roof
- Soft-metal evidence weathers away — dents remain but the fresh bright metal at the impact dulls within a season
- Splatter marks vanish within days, and those are some of the best evidence there is
Where the June 2023 damage concentrated
Hail is intensely localized. It is entirely normal for one street to take significant damage while the next street over sees nothing, which is why county-wide statements about a storm are close to useless for an individual homeowner.
What matters is your address. The corridor running east from Harrisburg through Lawnton and toward Hershey and the eastern county saw reports of significant hail, but the only reliable evidence is what is on your own property.
That is why every hail inspection we do starts on the ground with your soft metals — gutters, downspouts, drip edge, vent caps, window wraps and the fins on your air conditioner. Aluminum records honestly what fell at your house.
If you are only checking now
Be realistic about the claim position. Most policies require prompt notice, and a claim filed years after the event is difficult to attribute to it — which is exactly why we tell people to get inspected within days or weeks of any hail event.
That said, an inspection is still worth doing. Knowing that your roof has bruising means you can plan a replacement rather than discovering it through a leak, and it means you know to file promptly next time.
It also matters for resale. A roof with documented hail damage is a disclosure issue and a negotiation point, and you would rather know before a buyer's inspector does.
What to do differently next time
Photograph hailstones and splatter marks immediately
Stones next to a coin for scale, and the clean spots hail knocks onto deck rails and painted surfaces. Both disappear fast.
Walk the property and check every soft metal
Gutters, downspouts, caps, wraps, screens, AC fins, mailbox, grill. This takes ten minutes and it is your evidence.
Get a free inspection within days
Not months. Test squares marked and counted, each hit photographed with a scale reference, attic checked.
File promptly with the specific event date
Claims tied to a dated, documented storm are dramatically easier to get approved.
Consider Class 4 on the replacement
In a county that gets hail this size, impact-rated shingles are a defensible upgrade and most carriers discount for them.
The insurance discount worth asking about
Class 4 is the top rating under UL 2218 — the shingle survives a two-inch steel ball dropped twice on the same spot without the mat cracking.
Most carriers offer a homeowners premium discount for a Class 4 roof. Call yours and ask for the number before you choose a shingle. Across the twenty-five-year life of a roof, that discount frequently covers a substantial share of the upgrade cost, and in Dauphin County the performance difference is not hypothetical.
How we specify it is on our asphalt shingle roofing and hail damage roof repair pages.
What this means for your roof
If your street took that storm and you never had the roof looked at, the claim window has almost certainly closed. An inspection is still worth having: knowing you have bruising lets you plan a replacement rather than discovering it through a leak, and it is a disclosure issue at resale.
The more useful lesson is for next time. Photograph the stones and the splatter marks within days, check every soft metal at your address, and get inspected within weeks rather than months — see hail damage roof repair.
Questions we get about this
How do I know whether hail hit my specific address?
Your soft metals. Gutters, downspouts, drip edge, vent caps, window wraps and the fins on the outdoor AC unit all record what actually fell on your property. Hail is street-by-street, so county-wide storm reports tell you very little about your own roof.
Does hail damage get worse over time?
The bruising does not spread, but its effect compounds. Granules protect the asphalt from ultraviolet light, so every bruised spot ages at several times the rate of the shingle around it. That is why damage from a 2023 storm starts producing leaks years later.
Are impact-resistant shingles worth it in Dauphin County?
Frequently. Class 4 is the top rating under the UL 2218 test and most carriers discount premiums for it. In a county that keeps getting hail, ask your insurer what the discount is worth and weigh it against the upgrade across the life of the roof.
