A hail damage roof inspection is a slope-by-slope check for the specific marks hail leaves: bruised shingles that feel soft, knocked-off granules that expose the asphalt mat, and dents in soft metals like vents, flashing, and gutters. A good inspector does not eyeball the roof and guess. They chalk a 10-foot by 10-foot test square, count the qualifying hits inside it, and photograph collateral damage on the ground to build a claim an adjuster will accept.
Most homeowners book this inspection after a storm to decide whether to file an insurance claim. The trap is that many “free” inspections come from crews who knock on your door the same week, and their incentive is a signed contract, not an honest damage count. This guide covers exactly what a competent inspector checks, the test-square method adjusters actually use, and how to tell a real inspection from a sales pitch.
What does a hail damage roof inspection actually check?
A hail damage roof inspection checks four zones: the shingle field for bruising and granule loss, the soft-metal components for denting, the ground-level collateral (gutters, downspouts, AC fins, fence caps) for corroborating impact, and the interior or attic for water stains that signal an existing breach. Each zone is documented with dated photos because the roof surface tells only part of the story.
Hail damage is not always visible from the ground or even from a ladder at the eave. Fresh bruising can look normal to the eye and only reveal itself by feel, which is why a real inspection is tactile and methodical, not a two-minute drive-by. The inspector is building evidence, not just forming an opinion.
Shingle field: bruises, cracks, and soft spots
On asphalt shingles, hail leaves circular bruises where granules are driven into or off the mat, often with a soft, springy feel like the bruise on an apple. Inspectors press these spots by hand because subsurface fractures in the fiberglass mat frequently do not show as a clean crack from above. A bruise that feels soft counts as functional damage; a shiny spot with intact granules usually does not.
Granule loss and exposed asphalt
Hail knocks the protective granules off shingles, leaving dark, bare patches of asphalt that then age fast under UV. Inspectors distinguish storm granule loss (fresh, clustered, impact-shaped) from normal aging loss (uniform, gradual). Piles of granules in the gutters or at the downspout outlet after a storm are a supporting sign, though granules also shed from a new roof and from an old worn one, so context matters.
Soft metals: vents, flashing, and gutters
Soft metal components dent easily and are among the most reliable hail evidence on a house. Inspectors check turbine and box vents, pipe boots, ridge caps, valley and step flashing, and metal drip edge for round dents with a shiny center. Because these surfaces have no granules to complicate the read, a dent here is hard to dispute and helps date the storm.
Interior and attic signs
Inside, the inspector looks for fresh water stains on ceilings, damp or discolored attic insulation, and daylight or moisture at penetrations. Interior signs usually mean hail or an earlier issue already opened a path for water, which raises the urgency and can change a repair into a partial replacement. Not every hail-hit roof leaks immediately, so a clean attic does not rule damage out.
How the test square method works
The test square is the core measurement of a professional hail inspection. The inspector marks a 10-foot by 10-foot area (100 square feet) on a representative slope, then counts the hail impacts inside it that meet the definition of functional damage. That count, repeated on each slope, is what an adjuster uses to decide whether the slope, or the whole roof, gets replaced.
Insurers set their own thresholds, but roughly 8 qualifying hits within a 100-square-foot test area is a common trigger for replacing that slope. The number varies by carrier and by the InterNACHI-style damage definition being applied, so treat 8 as a benchmark, not a rule. Each slope is tested separately because a north face can pass while a west face fails, depending on storm direction.
| Element | What the inspector does | Why it matters |
|---|---|---|
| Test square size | Chalk a 10 ft by 10 ft (100 sq ft) area on each slope | Standardizes the count so slopes and claims are comparable |
| Hit count | Count only impacts that meet the functional-damage definition | Cosmetic marks do not qualify for replacement |
| Replacement benchmark | Roughly 8 qualifying hits per square (varies by carrier) | Determines whether a slope is repaired or replaced |
| Soft-metal chalking | Circle dents on vents, flashing, and gutters | Undisputable corroboration that hail struck |
| Ground collateral | Photograph AC fins, fence caps, mailbox, siding | Confirms hail size and direction without roof access |
Functional versus cosmetic is where most disputes happen. Functional damage compromises the shingle’s ability to shed water or shortens its service life; cosmetic damage is a mark that looks bad but does not affect performance. Metal roofs are the classic gray area here, and the split is covered in depth in the sibling guide on metal roof hail damage.
Free vs. paid hail inspections: which do you actually want?
A free hail inspection from a roofing contractor and a paid inspection from an independent inspector serve different purposes. The free version is a sales-driven damage assessment; the paid version (often 150 to 400 dollars) is a neutral report you can hand to an adjuster or buyer. For a straight claim after a known storm, a reputable contractor’s free inspection is usually fine, as long as you control the timeline.
| Free contractor inspection | Paid independent inspection | |
|---|---|---|
| Typical cost | 0 dollars | 150 to 400 dollars |
| Incentive | Win the repair contract | Deliver a neutral report |
| Best for | Clear post-storm claim with a trusted local roofer | Disputes, real-estate deals, second opinions |
| Main risk | Pressure to sign before the adjuster sees the roof | Out-of-pocket cost with no repair attached |
The general trade-offs between the two, across all inspection types and not just hail, are broken down in roof inspection cost. For hail specifically, the deciding factor is usually whether you already trust the roofer and whether an insurance dispute is likely.
Storm chaser red flags to watch for
Storm chasers follow hail maps, canvass neighborhoods door to door, and push a “free inspection” that is really a lead-gen funnel. Legitimate established roofers rarely knock cold. The most damaging tactic is manufactured evidence: crews have been caught denting shingles or cracking flashing with a tool during the “inspection” to fabricate a claim. Slowing the process down is the single best defense.
- Door-to-door with urgency. Anyone offering a same-day or “today only” deal after a storm is selling, not inspecting.
- Claims your insurer sent them. Carriers notify you before dispatching anyone; a stranger citing your insurer is a lie.
- Wants to start before the adjuster. Reputable roofers wait for the carrier’s inspection; chasers push to work first.
- Refuses references or a license number. A local, licensed roofer has nothing to lose from a week of due diligence.
- Vague on the test-square count. If they cannot show you photographed hits per slope, the “damage” is not documented.
What to do before and after the inspection
Before booking, do a safe ground-level check and call your insurer, then schedule with a roofer you chose rather than one who chose you. After the inspection, get the report in writing with dated photos per slope before you sign anything or file. The order of operations protects both your safety and your claim.
- Stay off the roof. Wet, hail-struck shingles are slick and hide weak spots; inspect from the ground and leave the surface to a pro.
- Log the storm. Note the date, approximate hail size, and any local weather reports; this dates the damage for the claim.
- Photograph ground collateral. Dented gutters, downspouts, AC fins, and fence caps corroborate the roof damage from a safe vantage.
- Call your carrier first. Understand your deductible and claim window before a contractor frames the decision for you.
- Get the report in writing. Insist on per-slope test-square photos and a written damage summary before authorizing work.
If the inspection confirms damage, the next steps split into the claim path and the repair path. The claim side, including how the adjuster’s visit differs from a contractor’s, is covered in insurance adjuster roof inspection, and the threshold question of how much damage forces a full replacement is detailed in how much hail damage it takes to replace a roof. Once scope is set, the actual fix is walked through in hail damage roof repair.
How often does hail damage lead to a replacement?
Hail is one of the largest drivers of residential roof claims in the United States, and in high-frequency hail states a single severe storm can trigger neighborhood-wide replacements. Whether your roof crosses the line depends on the per-slope hit count, the shingle’s age and condition, and your carrier’s functional-damage standard. State-by-state hail claim volume and 10-year loss trends are tracked in the 2026 Roofing Hail and Storm Loss Database.
Age matters as much as impact count. A 4-year-old roof with 6 hits may be repaired, while a 16-year-old roof with the same count often gets replaced because the remaining service life is short and matching discontinued shingles is impractical. This is judgment, not arithmetic, which is why the documented test-square evidence carries the argument. For the full slope-by-slope checklist an inspector runs, see the 30-point roof inspection checklist.

Frequently asked questions
How long after a hailstorm should I get a roof inspection?
Schedule the inspection within a few weeks of the storm, and before you file, so the damage is fresh and clearly datable. Most insurers set a claim window (often 6 to 12 months, varying by policy and state), but waiting invites arguments that the damage predates the storm. Booking promptly with a roofer you chose, not one who knocked on your door, keeps both the evidence and the claim clean.
How many hail hits does it take to replace a roof?
Roughly 8 qualifying hits inside a 10-foot by 10-foot test square is a common benchmark for replacing that slope, but the number varies by insurer and by the functional-damage definition applied. Only hits that compromise the shingle count; cosmetic marks do not. Each slope is tested separately, and shingle age and condition also weigh into whether a slope is repaired or fully replaced.
Is a free hail damage roof inspection worth it?
A free inspection from a reputable local roofer is usually fine for a clear post-storm claim, as long as you control the timeline and get documented per-slope photos. The risk is that some free inspections are sales funnels, and a few dishonest crews manufacture damage. For disputes, second opinions, or real-estate deals, a paid independent inspection (often 150 to 400 dollars) gives you a neutral report instead.
What does hail damage look like on a roof?
On asphalt shingles, hail leaves dark circular bruises where granules are knocked off, exposing the black asphalt mat, and the bruised spots often feel soft to the touch. On soft metals like vents, flashing, and gutters, hail leaves round dents with a shiny center. Fresh, clustered, impact-shaped granule loss points to a storm, while uniform gradual loss usually just means age.
Can I inspect my roof for hail damage myself?
You can and should do a ground-level check, gutters, downspouts, AC fins, fence caps, and siding for dents, but do not climb onto the roof. Hail-struck shingles are slick and can hide weak spots and damaged edges, making a fall likely. A trained inspector reads bruising by feel and runs test squares, which is hard to replicate safely from a ladder, so leave the roof surface to a professional.
What is a test square in a hail inspection?
A test square is a chalked 10-foot by 10-foot area (100 square feet) on a roof slope where the inspector counts the qualifying hail hits. It standardizes the damage count so each slope and each claim can be compared on the same basis. Adjusters and inspectors use the per-square count, together with soft-metal denting and ground collateral, to decide whether a slope is repaired or replaced.
