What Hail Damage Looks Like on a Roof (and What It Doesn’t)

Knowing how to tell if a roof has hail damage starts on the ground, not on a ladder. Hail leaves a random scatter of bruises, cracks and dark spots on shingles, and it nearly always marks softer things around the house too: gutters, downspouts, vents and outdoor air conditioner units. This guide shows what real hail damage looks like on a Columbus, Georgia home, the common look-alikes that are not hail, how hail size relates to risk, and how to photograph what you find. It covers identification only. Nothing here asks you to go up on a roof.

Signs a Roof Has Hail Damage

Hail damage on asphalt shingles shows up as a random pattern of impact marks, bruises that feel soft when pressed, and cracks or breaks where a stone struck. Granules may be knocked loose, leaving dark, round spots. The clearest confirmation is matching dents or spatter marks on gutters, vents and other soft metal around the house.

That description comes from the Insurance Institute for Business and Home Safety (IBHS), the insurer-funded research body, in its guide Is it hail damage?. IBHS lists three signs of real hail damage:

SignWhat it looks likeWhere a homeowner sees it
Random impact marksSpots with no pattern or line, scattered across a slopeBinoculars from the yard; a roofer’s photos
BruisingSoft spots that give when pressedOnly a roofer on the roof can feel these
Cracks or breaksSplit or broken shingle where hail struckSometimes visible from the ground on low slopes

The word “random” matters. Hail falls in a scatter, so marks with no line, no repeat spacing and no connection to where people walk are the strongest visual hint. Damage that follows a straight line, sits only along one edge or appears in the same spot on every shingle usually has another cause.

The direction of the storm matters too. Slopes facing the wind that carried the hail often show more hits than the sheltered side, so a roofer will compare slopes before drawing conclusions.

Storm Safety Before You Look

After a hailstorm, stay inside until lightning has passed, keep away from any downed power lines and call 911 if a line is down or anyone is hurt. Do not climb onto a wet or damaged roof. Everything useful for a first check can be seen from the ground, a window or the attic hatch.

A hail-damaged roof is slippery, often loose and sometimes hiding holes under displaced shingles. Even experienced roofers wait for a dry surface. Climbing up to look is the riskiest part of a hail event for most homeowners and is not needed to decide whether to call for an inspection.

If water is coming in, move belongings away from the drip, put a bucket underneath and keep people out of rooms where the ceiling is bulging.

Be careful, too, with anyone who arrives at the door offering to check the roof straight after the storm. Our guide to free roof inspection offers and how the scams work explains what to watch for.

Ground-Level Clues Around the House

The best evidence of hail is often on the things around your roof, not the shingles. IBHS advises looking for spatter marks or impact dents on air conditioner units, gutters, metal flashing, downspouts and even patio furniture. Soft metal dents easily, so fresh dents there show hail of meaningful size reached your property.

Walk the outside of the house once the storm has passed and the ground is safe. Check, in this order:

  1. Gutters and downspouts. Small round dents along the front edge or the downspout elbows.
  2. Outdoor air conditioner unit. Dents in the thin fins on the top and sides.
  3. Window screens and wooden trim. Holes in screens, fresh dings in painted wood.
  4. Vehicles, mailbox, patio furniture. Dents or chipped paint on anything left outside.
  5. Splash blocks and driveway. A heavy scatter of shingle granules below the downspouts.

Spatter marks are the other clue. A hailstone can knock the dirt and oxidation off a surface, leaving a clean, round mark on a painted fence, a deck rail or a metal box. Those marks fade within weeks, so photograph them soon.

Fresh dents in soft metal do not prove the shingles were damaged, but no dents anywhere makes significant shingle damage less likely. The pattern of evidence is what a roofer and, later, anyone assessing the roof will look at.

Hail Size and What It Can Do

The National Weather Service defines a severe thunderstorm partly by hail at least 1 inch in diameter, about the size of a quarter. Hail that size and larger is where damage to roofs becomes a real concern. Smaller hail can still mark gutters, and shingle age changes how much damage a given size causes.

The definition is in the Storm Prediction Center’s frequently asked questions: a severe thunderstorm produces hail at least 1 inch in diameter, wind gusts of 58 mph or more, or a tornado. The Storm Prediction Center’s hail size chart gives the common comparisons used in storm reports:

ObjectDiameter
Penny0.75 inch
Quarter1.00 inch
Half dollar1.25 inches
Ping pong ball1.50 inches
Golf ball1.75 inches
Hen egg2.00 inches
Tennis ball2.50 inches

The Storm Prediction Center encourages measuring hail rather than estimating it. If you can do so safely after the storm, put a few stones next to a ruler or a coin and photograph them before they melt.

Bruises, Cracks and Exposed Mat

On the shingle itself, hail leaves three kinds of mark: a bruise where the mat underneath was crushed, a dark spot where granules were knocked off and the asphalt shows, and a crack or tear in the shingle. Bruises and cracks are what turn a cosmetic mark into a place where water can eventually get in.

IBHS describes bruising as soft spots you can feel when pressing on the shingle. That is a test for a roofer standing on the roof, not a homeowner. What you can see from the ground, with binoculars, is the dark round spot left where granules were knocked away.

The granules on an asphalt shingle protect the asphalt from sunlight. Where hail strips them, the exposed spot weathers faster, which matters in Columbus, where NOAA’s 1991 to 2020 climate normals for the Columbus Metropolitan Airport station put the normal July high at 92.9 degrees.

Some shingles are built to resist hail. IBHS runs an impact-resistant shingle rating program that tests for dents, tears and granule loss. When a roof is replaced after hail, ask what impact rating the proposed shingle carries.

Look-Alikes That Are Not Hail

Several kinds of wear look like hail at a glance. IBHS lists granule loss along shingle edges from natural weathering, uniform wear or discoloration, manufacturer defects, marks from installation, tools or people, and granules knocked off by heavy rain. Blistering, where small bubbles in the asphalt pop and leave pits, is another common mix-up.

The way to tell them apart is the pattern:

MarkLooks likeTells it apart
Hail hitRandom dark spot, bruise or crackRandom scatter; matching dents on soft metal
BlisteringSmall pits where bubbles burstOften in clusters or all over a slope, with no metal dents
Edge weatheringGranule loss along shingle edgesFollows the edges, not random
Uniform agingOverall thin, faded or patchy lookEven across the slope
Foot traffic or toolsScuffs, crescent dents, scrapesAlong walking paths or near vents and edges
Manufacturing defectRepeating marks or cracksSame place on many shingles

Age is the most common confusion. A roof near the end of its life sheds granules and cracks on its own, with or without hail. Our guide to how long a roof lasts in Georgia heat and rain explains what normal aging looks like.

Photographing Damage for the Record

Good photos taken soon after a storm make every later conversation easier. Photograph the date-stamped damage from the ground: dented gutters, the air conditioner unit, spatter marks, granules at the downspouts, any hail you saved, and any interior stains. Add a coin or ruler for scale, and note the date and time of the storm.

A simple record that a roofer can work from:

  • Wide shots of each side of the house, then close-ups of dents and marks.
  • Any hailstones beside a ruler or coin, before they melt.
  • Granule piles at downspout outlets.
  • Ceiling or attic stains, with the date.
  • Your own note of when the storm hit and how long the hail lasted.

Keep the originals unedited. If a roofer inspects, ask for their photos too, each labelled with the slope it came from.

Columbus Storm Seasons and Wind

Columbus has a long record of severe weather that brings hail and high wind together. FEMA’s disaster declarations for Muscogee County include severe storms and tornadoes in 2007 and severe storms in 2016, alongside hurricanes. A declaration is not a hail count, but it shows the area sits in the path of storms that damage roofs.

The source is FEMA’s OpenFEMA declarations for Muscogee County, which also lists Hurricanes Opal, Irma, Michael and Helene. Local hail event counts are not stated here because no primary source for them could be confirmed.

Hail often arrives with strong wind, and wind damage looks different: lifted, creased or missing shingles rather than round marks. Our guide to hidden roof damage after storm winds covers that side.

Next Steps After a Hail Storm

If the ground-level clues point to hail, the next step is an inspection by a roofer who documents each slope with photos. A roofer can feel for bruises, check cracks and tell hail from wear, which a homeowner cannot safely do from the ground. Then decide on repair with the photos in hand.

Emergency Roofing Columbus provides hail and storm roof repair and can inspect and photograph each slope. Call (706) 418-8677.

Frequently asked questions

What does a roof look like if it has hail damage?

A hail-damaged asphalt roof shows a random scatter of dark spots where granules were knocked off, soft bruises and sometimes cracked shingles. IBHS also points to dents or spatter marks on gutters, downspouts, flashing and outdoor air conditioner units as supporting evidence. A roofer confirms it on the roof.

Can 1 inch hail damage a roof?

It can. The National Weather Service treats hail of 1 inch, about quarter size, as severe, and that is the size where roof damage becomes a real concern. Whether a particular roof is damaged depends on the shingle type, its age and condition, and the wind. A roofer’s inspection confirms it.

How can I tell if my roof was damaged by hail?

Start on the ground. Look for fresh dents on gutters, downspouts and the outdoor air conditioner unit, spatter marks on painted surfaces, and piles of granules at downspout outlets. With binoculars, look for random dark spots on the shingles. Then have a roofer check for bruises and cracks.

What is the difference between blistering and hail damage on shingles?

Hail hits are random and usually come with dents on nearby soft metal. Blistering forms small pits where bubbles in the asphalt burst, often clustered or spread evenly across a slope, with no matching metal dents. IBHS lists manufacturer defects and weathering among the look-alikes that are not hail.

How long will a roof last after hail damage?

It depends on how badly the shingles were hit. Granule loss exposes asphalt to the sun and speeds up weathering, while cracks and bruises can let water in sooner. There is no fixed figure; a roofer’s inspection of the damaged slopes is the way to judge whether repair or replacement makes sense.
