So what does hail damage look like on a roof? Randomly scattered circular spots where the granules got knocked away, each one hiding a soft bruise you can feel under your fingers, like the bruise on an apple. You’ll usually spot matching dents in gutters, downspouts, and roof vents before you ever see the shingle damage itself, and you’ll almost never see any of it clearly from the driveway, which is exactly why so much hail damage goes unclaimed.
Quick answer: Hail damage on a roof in Pittsburgh is easy to miss from the ground. What bruising looks like, where to check, and how long you have to file.
Here’s the physics of the problem. A hailstone the size of a quarter hits your shingles at highway speed. It doesn’t punch a hole. It doesn’t tear anything off. From the ground the next morning, the roof looks exactly like it did last week. The most expensive kind of damage we inspect is the kind homeowners never see, and by the time it announces itself as a stain on the bedroom ceiling, the storm that caused it is a year in the past and the claim has gotten complicated. We’ve inspected thousands of roofs around Irwin, Murrysville, and Greensburg since 1995. Here’s what hail actually does up there, and how to know whether your roof took a hit worth filing over.
What a hail bruise actually is
An asphalt shingle is a fiberglass mat coated in asphalt and topped with ceramic granules. Those granules aren’t decoration. They’re the sunscreen that protects the asphalt from ultraviolet light. When hail strikes, the impact knocks granules loose and, more importantly, fractures the mat underneath. The surface may look mostly intact, but the structure below it is broken.
That fracture is why hail damage is a slow disaster instead of a fast one. The bruised spot sheds its remaining granules over the following months, the exposed asphalt bakes and cracks in the sun, and our freeze and thaw cycles pry the crack open a little wider every winter. A roof that took hail in June might not leak until the second or third winter after. By then, most people have forgotten the storm entirely.
Bruising versus ordinary granule loss
Every asphalt roof sheds granules. You’ll find them in gutters and at the bottom of downspouts on a perfectly healthy roof, especially a newer one shedding its loose excess. Ordinary wear shows up as thin, evenly distributed loss across sun facing slopes. Hail is different. Hail leaves scattered impact marks, circular spots of missing granules with a bruise you can feel underneath, often concentrated on the slopes that faced the storm.
That distinction can decide your hail damage roof insurance claim. An adjuster who calls hail bruising “normal wear” has just turned a covered loss into your problem. Knowing the difference, and photographing it properly with chalk marks and a test square, is a big part of what a professional inspection brings to the table.
Check the soft metals first
Here’s an inspector’s trick you can use from the ground. Hail hard enough to bruise shingles almost always dents the soft metals first: aluminum gutters, downspouts, window wraps, the fins on your air conditioner condenser, box vents and pipe flashings up on the roof. Walk around the house after a storm and look down the length of your gutters in raking light. Little dimples every foot or two? Your shingles very likely took hits too.
We use soft metal damage the same way adjusters do, as corroborating evidence. Dented vents and gutters establish that hail of a damaging size fell on this specific house, which makes the shingle bruising much harder to dispute. If the storm just passed through, start with our storm damage checklist for the first 48 hours so the photos and paperwork begin on the right foot.
Why you can't judge it from the driveway
Hail bruises are small, low contrast, and spread across a surface you’re viewing at a sharp angle from 25 feet below. Even trained eyes can’t reliably spot them from the ground. It takes someone on the roof, looking straight down at the shingles, often crouched and feeling for soft spots by hand. Our roof inspection checklist lays out everything a thorough inspection covers, and hail bruising sits near the top of the list of things that simply can’t be checked from the yard.
The housing stock around here adds its own wrinkle. A lot of the 1950s ranches in North Huntingdon and Penn Township have low, walkable slopes where damage hides in plain sight, while the older brick foursquares in Jeannette and Trafford have steep faces nobody has looked at closely in decades. Either way, the answer isn’t binoculars. It’s boots on the roof, with fall protection, by someone who knows what a bruise looks like.
The clock is already running
Pennsylvania homeowners generally have a limited window to file a hail claim, commonly around one year from the date of the storm under many policies, and every policy requires prompt notice of a loss. Wait too long and you run into two problems at once. The insurer can argue late notice, and the damage itself becomes harder to tie to a specific storm date because weathering blurs the evidence. Our walkthrough of the roof insurance claim process in Pennsylvania covers the timeline and the paperwork in detail.
Our advice is simple. If hail fell in your neighborhood, get the roof inspected within a few weeks, even if everything looks fine from the yard. A documented inspection dated close to the storm is the strongest piece of paper in any claim file. If we find nothing, you’ve lost an hour and gained peace of mind.
What a real hail damage inspection looks like
When we run a hail damage inspection in the Pittsburgh area, we photograph the date stamped evidence adjusters expect: overview shots of each slope, test squares showing hits per square, close ups of bruises with a chalk circle around them, and every dented soft metal on the property. As an Owens Corning Platinum Preferred contractor with an A+ rating from the BBB, we’ve sat through a lot of adjuster meetings in Westmoreland and Allegheny counties, and we build the file the way the person approving the claim needs to see it. If the damage is real, we’ll meet the adjuster on your roof, point to every mark, and handle the storm damage roof repair from the first tarp to the last shingle.
And if it’s not real, we’ll say so. We built this company on referrals, and telling a neighbor in Export or Delmont the truth about a healthy roof is worth more to us than any single job.
Frequently asked questions
What size hail does it take to damage a shingle roof?
Hail around one inch, quarter sized, is the usual threshold for damage to standard asphalt shingles, though older or brittle roofs can bruise from smaller stones. Larger hail damages nearly everything it touches, including shingles rated for impact.
Why did my neighbor get a new roof approved while my hail claim was denied?
Different insurers, different adjusters, different documentation. Hail also falls in narrow swaths, so damage genuinely varies house to house. But in our experience the documentation gap explains most denials, which is why we inspect and photograph before the adjuster ever climbs a ladder.
Does hail damage always mean a full roof replacement?
No. A slope with a handful of bruises can sometimes be repaired. But when hits are scattered across multiple slopes, replacement is usually the right call, because every bruise is a future leak and insurers generally pay to restore the whole covered loss, not patch it piecemeal.
How long do I have to file a hail damage roof insurance claim in Pennsylvania?
Most policies expect prompt notice, and many set a filing window of roughly a year from the storm date. The practical deadline is shorter, because fresh damage is far easier to tie to a specific storm. Get an inspection within a few weeks of any hail event and file while the evidence is crisp.
