How do you know if your roof has hail damage?
Start at ground level with the soft metals: dents in gutters, downspouts, window screens and the fins on the AC unit show that hail big enough to matter came through. On an asphalt roof, a hail hit looks like a dark spot where the granules were knocked loose, often soft when pressed. Hail usually has to be about an inch across to damage a shingle, and most of that damage cannot be seen from the yard, so a close inspection is what settles it.
Hail damage is easiest to read on the soft metals first
Before anyone looks at a shingle, walk the outside of the house. Aluminum gutters and downspouts dent easily, so a row of round dings along the gutter face is a quick sign of how big the hail was. Check the painted metal around the garage door and the fins on the outdoor AC unit, which fold flat where hail struck them.
The metal on the roof tells the same story from closer up. Turtle vents, ridge vent caps, the chimney cap and the lead or painted flashing around pipes all take dents. If those are marked, the shingles beside them took the same hits.
Pay attention to which side of the house is marked. Storms in North Texas usually drive hail in from one direction, so dented screens and spatter marks on the west and north faces with nothing on the east often mean the slopes facing west and north need the closest look.
On asphalt shingles, a hail hit leaves a bruise
A hail strike knocks the protective granules off in a rough circle and exposes the dark asphalt underneath. Press on a fresh hit and it can feel soft, like a bruise on an apple. That softness means the fiberglass mat inside the shingle has fractured, and it is the part adjusters care about most.
The hits land at random. Damage that follows a straight line, sits only where people walk, or looks like small raised pimples spread evenly across the roof is usually something else: foot traffic, installation marks or blistering from heat and age.
Hail damage rarely leaks right away. The exposed asphalt bakes in the sun, cracks, and starts letting water through a year or two later, long after the storm has been forgotten. That delay is why so many hail roofs go unnoticed until the filing window on the policy is closing.
Wind leaves different marks. Look for a straight crease across a shingle where the tab folded back, or tabs missing altogether. A creased shingle has lost its seal and will keep lifting in every storm after.
Adjusters count hits inside a ten-by-ten test square
Insurance inspections usually mark a test square, ten feet by ten feet, on each slope that faced the storm, then count the hits that damaged the shingle inside it. Carriers set their own thresholds, and many look for somewhere around eight to ten damaging hits in a square before they approve replacing that slope.
That is why a handful of scattered marks may not add up to a claim while a roof with dented metal all around it does. It also explains why two slopes on the same house can get different answers.
Stay off the roof yourself. Steep pitches, loose granules and summer shingle temperatures make it dangerous, and a hot shingle scuffs under a boot. Binoculars from the yard, or photos taken from a second-story window, will show you enough to decide whether to call someone.
Door-knockers arrive with the storm
After a big hail day in Dallas-Fort Worth, out-of-town crews knock on doors across the affected neighborhoods. Before you sign anything, get a written estimate, confirm a local physical address, and check that the company carries insurance.
Texas law gives you some protection. A contract for roof work that will be paid through an insurance claim has to let you cancel within three days of learning the claim was denied, and a contractor cannot act as your public adjuster.

How big does hail have to be to damage a roof?
Hail around one inch across, about the size of a quarter, is usually where asphalt shingles start to take real damage. Smaller hail can still dent gutters and screens, and older, sun-dried shingles break more easily than new ones.
Are granules in my gutters a sign of hail damage?
They can be. New roofs shed loose granules for the first year or so, and older roofs shed them slowly with age. A heavy pile at the bottom of the downspouts right after a storm, especially alongside dented gutters, points to hail.
Can a roof have hail damage and not leak?
Yes, and most do at first. A hail hit fractures the shingle mat and strips the granules, and the leak usually follows months or years later as the exposed spot weathers and cracks.
