Hail claims are won and lost at the inspection. The damage is real or it is not, and the documentation either proves it or it does not. This guide covers what hail actually does to a roof, how to tell true hail bruising from the look-alikes, and how to document a hail roof so the claim survives an adjuster who has already said "wear and tear" twice today.
What hail actually does to an asphalt shingle
A hailstone is a rock made of ice arriving at speed. On asphalt shingles it does one or more of three things: knocks granules loose (the visible bruise), fractures the mat under the granules (the functional damage that shortens roof life), and loosens the granule-to-asphalt bond around the strike so the spot sheds granules for months. That third one is why a marginal hail roof often looks worse a season later.
The field marks of real hail
- Random distribution. Hail does not fall in lines or patterns. Strikes scatter across a slope, heavier on the sides facing the storm.
- Bruises, not bald spots. A strike is roughly circular granule loss, sometimes with a soft, crushed feel when pressed gently.
- Directionality. Wind-driven hail hits some slopes harder. A roof with heavy damage on the west and north faces and little on the east tells a coherent story.
- Collateral damage. Soft metals remember: dings on gutters, downspouts, ridge vents, flashing, window wraps, AC fins and mailboxes. Adjusters trust metal because metal does not age into false positives.
The look-alikes that sink claims
- Blistering: heat-related bubbles that pop and leave crater-like spots, usually with granules intact around a clean rim, often clustered rather than random.
- Foot traffic: scuffed granule loss in walking paths and near penetrations, in patterns no storm would draw.
- Age and granule fatigue: uniform thinning, heaviest in water channels, without mat fracture.
- Mechanical damage:the satellite installer's knee, the pressure washer, the tree limb. Localized and explainable.
Calling a blistered roof hail is how contractors lose adjuster trust and how claims earn the wear-and-tear denial. The inspection exists to make the honest call; the good news is that honest and well-documented wins more claims than optimistic and vague.
The inspection routine
- Start on the ground: gutters, downspouts, window wraps, AC fins, fence caps, mailbox. Photograph every ding before touching the roof.
- Walk every slope with the sun at a useful angle. Chalk-circle representative strikes; do not chalk the whole roof into a crime scene.
- Test squares where appropriate: a 10x10 area per slope with strikes counted is how many carriers evaluate density.
- Photograph in layers: address shot, whole-slope overviews, mid-range context, close-ups with something for scale. Organized by slope, stamped by date.
- Check the soft spots: ridge caps and vents often show hail first; skylights and their flashing tell clean stories.
Anchor the date of loss with data
"There was a big storm this spring" is not a date of loss. Verified weather history (hail size, wind speed, storm reports near the address on a specific date) anchors the claim, supports causation and matters more as time passes. RoofGrid pulls NOAA storm history for any address, generates a court-ready weather evidence report, and can scan up to three years of verified storms to rank candidate dates when the homeowner is not sure when the damage happened.
From inspection to claim
A hail inspection that ends in a handshake evaporates. The pipeline: photos organized to the job file, the takeoff measured, the weather evidence attached, the homeowner walked through what happens next, and the claim tracked with its deadlines computed from day one. That is the boring machinery that turns storm season into a book of business instead of a pile of chalk marks.
Common questions
What size hail damages a roof?
Rules of thumb: around 1 inch (quarter size) can bruise aging three-tab shingles; 1.25 to 1.5 inch (half dollar to ping-pong ball) threatens most asphalt roofs; larger hail damages nearly anything it hits. Age, shingle quality, roof pitch and wind driving the hail all move the line, which is why verified hail size for the address matters more than the rule of thumb.
What does hail damage look like on asphalt shingles?
A bruise: a roughly circular spot where granules were knocked away, often with a soft feel underneath, distributed randomly across a slope with matching dings on soft metals. It does not look like neat lines (foot traffic), popped round blisters with granules intact at the edges (blistering), or uniform bald patches (age).
How soon after a hail storm should the roof be inspected?
Soon, for two reasons: evidence quality and deadlines. Collateral damage like metal dings stays crisp early, and some states run hard statutory windows on filing claims and supplements from the date of loss. The storm date itself should be anchored with verified weather data, not memory.
Will an insurance company deny hail damage as wear and tear?
It is the most common dispute in hail claims. The counter is documentation: verified hail at the address on a specific date, collateral damage that wear cannot explain, and photos that distinguish bruising from blistering and foot traffic. Claims documented that way get argued far less than claims supported by a feeling.
