A hail damage estimate is built from four things an appraiser counts panel by panel: how many dents are on each panel, how big those dents are, what the panel is made of, and whether paint is broken anywhere in the pattern. Those four inputs decide whether the job is paintless dent repair, conventional fill-and-paint, or a full panel replacement — and whether the total even makes sense to run through insurance. This page walks through each factor with real, dated pricing-matrix examples. It does not quote AAR’s own prices or tell you what your vehicle needs; that’s an in-person inspection.
What a hail estimate actually counts
A single-dent estimate and a hail estimate are built from different math, because hail damage is never one dent — it’s a pattern.
A hailstorm leaves dozens to hundreds of individual dents across every horizontal and near-horizontal surface: hood, roof, trunk lid, and the upper edges of fenders and doors. Instead of pricing one dent, an appraiser works panel by panel, counting how many dents sit on each one and sorting them by size. That panel-by-panel count is the backbone of every hail estimate, and it’s why two cars parked ten feet apart in the same storm can come back with very different numbers — one may have taken a glancing hit on the roof, the other a direct hit across hood, roof, and trunk. A panel too damaged for PDR is priced as a repair or replacement; what a fender repair quote includes shows that math for a fender.
Dent size classes: dime to half-dollar
Estimators don’t measure every dent in inches — they sort them into a small set of size classes, and the class matters more than the exact millimeter count.
The PDR hail matrix used across the industry — and referenced by insurers when scoping hail claims — sorts dents into four size classes: dime, nickel, quarter, and half-dollar. On a panel with a mix of sizes, the estimator reads the dominant size and prices the panel against that class rather than averaging every dent individually, according to IA Path’s published explainer on reading a PDR hail matrix (updated September 30, 2022). Anything bigger than a half-dollar is priced as an oversized dent and typically adds a flat surcharge per dent — StormWise’s published hail-PDR pricing guide (published December 7, 2020) puts that surcharge at $40 per oversized dent, on top of the base panel price. The per-dent pricing behind most hail estimates is explained in what a paintless dent repair quote includes.
Dent count bands per panel
How many dents land on a single panel changes the labor time more than almost any other input, so matrices group dent counts into bands rather than pricing each dent as a flat add-on.
A panel with a handful of dents takes meaningfully less time to work than the same panel packed with dents, because a tech has to access and massage each one individually from behind the metal. StormWise’s matrix illustrates this with a worked example: a left rear door carrying 16 to 30 nickel-sized dents prices out around $200, and the identical door with the same dent count in quarter-sized dents rises to about $225 — the size class shifts the number even when the count band stays the same. Doubling or tripling the dent count on a panel moves the estimate up a full band, not by a small percentage.
Panel count across the vehicle
A hail estimate totals across every damaged panel, not just the worst one, which is why the full-vehicle number is usually far larger than any single-panel line item suggests.
Hood, roof, trunk lid, and the tops of the fenders and doors typically take the worst of a storm because they face upward; lower door panels and rocker areas are shielded by the vehicle’s own shape and often escape with light or no damage. An estimate lists every affected panel with its own dent count and size class, then sums the line items — so a car with moderate damage spread across six panels can total more than a car with severe damage on just two. StormWise’s guide puts full-vehicle PDR hail repairs in a broad range of roughly $2,500 to more than $10,000, driven almost entirely by how many panels are involved and how dense the damage is on each one.
Panel material: steel, aluminum, high-strength steel
The metal underneath the dent changes the labor difficulty, and matrices build that difference in as a direct markup on top of the base panel price.
Standard steel is the baseline the matrix is built around. Aluminum and high-strength steel panels — common on hoods and increasingly on full body structures — resist the massaging technique PDR depends on, and IA Path’s matrix explainer states the adjustment plainly: multiply the base sublet price by 1.25, a 25% markup, for aluminum or high-strength-steel panels. StormWise’s worked example shows the effect on a real line item: a hood with 15 quarter-sized dents that would price at $175 on standard steel comes to $218.75 once the 25% aluminum markup is applied.
When paint is broken: PDR stops being an option
Whether the paint survived the hail is the fork that decides which repair method applies, exactly as it does on a single-dent job — but on a hail-damaged vehicle it can apply to some panels and not others.
Paintless dent repair only works on intact paint, because the technique massages the metal back into shape without cutting, filling, or repainting. A hailstorm severe enough to crack paint on impact — usually the larger, harder hits — takes those specific panels out of the PDR column even while the rest of the vehicle stays PDR-eligible. That’s a common outcome on a mixed hail estimate: most panels go through PDR, one or two with broken paint go to conventional fill-and-paint, and the final invoice blends both methods on the same vehicle.
PDR vs. conventional repair vs. panel replacement
These are the three paths a hail-damaged panel can take, and a hail estimate should say plainly which one applies to which panel — not treat the whole vehicle as one method.
| Method | What it involves | Best fit on a hail job | What it doesn’t fix |
|---|---|---|---|
| Paintless dent repair (PDR) | Massaging each dent back into shape from behind or alongside the panel; no cutting, filling, or repainting | The large majority of hail dents, when paint is intact and the panel’s back side is reachable | Broken paint, panels with no back-side access, dents near reinforcement bracing |
| Conventional fill-and-paint | Reshape what can be reshaped, fill remaining low spots with body filler, prime, blend, and repaint | Panels where paint cracked on impact, or where dent density is too high for clean PDR access | Structural damage behind the panel, torn or severely stretched metal |
| Panel replacement | Remove the damaged panel and install a new one, then paint and blend to match | Roof or hood sections with dent density and bracing that make PDR or fill-and-paint impractical, or panels with sensor housings that can’t tolerate reshaping | Nothing on the new panel itself, but adds parts cost and paint-match risk |
Which panels need which method is a vehicle-specific call the shop makes after inspecting the full pattern in person, not something a size-class table can decide for a reader.
When an insurer calls a hail-damaged car a total loss
Hail is one of the more common causes of a total-loss call, because it damages the entire vehicle at once instead of one panel.
Progressive’s published consumer guidance on hail claims (last updated March 7, 2024) explains that a severe enough hailstorm can total a vehicle outright, since hail damages the whole car rather than one panel — and that when a repair estimate exceeds the vehicle’s actual cash value under a state’s total-loss threshold, the insurer pays the cash value minus the deductible instead of authorizing repairs. That threshold and the underlying cash-value figure are insurer- and state-specific; nothing here is legal or coverage advice, and the only way to know where a specific vehicle lands is the insurer’s own inspection.
Filing a claim vs. paying out of pocket
Whether to file a hail claim is a math comparison, not a legal one, and the comparison is the same one that applies to any comprehensive claim.
Hail damage is covered under comprehensive coverage, not collision coverage — Progressive’s guidance is explicit that a policy without comprehensive coverage won’t pay for hail repairs at all. When coverage is in place, the driver pays the comprehensive deductible first, and the insurer covers the remainder up to the policy’s limit. Progressive’s own rule of thumb: "If your repair estimate amount is less than your deductible or close to it, you’re better off paying for the repairs out of pocket." The same guidance notes that filing a claim can affect a policy’s rate at renewal, and that insurers weigh claim history differently from one company to the next — which makes the deductible-versus-estimate comparison the first thing worth doing, before a claim is filed at all.
Matrix pricing examples: dated and sourced
Real, published matrix figures show the range better than a made-up number. These come from PDR pricing guides that publish their matrix logic, not from AAR:
| Panel / scope | Size class | Estimate | Date / source |
|---|---|---|---|
| Left rear door, 16–30 dents | Nickel | ~$200 | StormWise published PDR hail-pricing guide, December 7, 2020 |
| Left rear door, 16–30 dents (same panel, larger size class) | Quarter | ~$225 | StormWise published PDR hail-pricing guide, December 7, 2020 |
| Hood, 15 dents, aluminum panel (25% markup applied) | Quarter | ~$218.75 | StormWise published PDR hail-pricing guide, December 7, 2020 |
| Full vehicle, moderate-to-severe multi-panel damage | Mixed | roughly $2,500–$10,000+ | StormWise published PDR hail-pricing guide, December 7, 2020 |
These are published matrix line items from one PDR pricing guide, not a national average, an insurer’s fixed schedule, or an AAR estimate. A given insurer’s own matrix, and the specific dent pattern on a specific vehicle, will price differently.
Storm-chaser caution: what BBB warns to watch for
A hailstorm draws out-of-town repair outfits along with legitimate local shops, and the difference matters more on a multi-thousand-dollar hail job than on almost any other repair.
The Better Business Bureau’s Texas guidance after a hailstorm (published April 21, 2026, covering an East Texas hail event) lists the tells: contractors who show up door-to-door unsolicited, demand full payment upfront before work starts, use high-pressure sales tactics, and skip a written contract. BBB East Texas president Michelle Mills put the risk plainly: unscrupulous operators "take the money and run" once a homeowner or driver pays in full before work begins. The BBB’s recommended steps apply directly to a hail-damaged vehicle: contact your insurer first to understand what the claims process actually requires, get more than one estimate, initiate contact yourself rather than responding to an unsolicited knock or flyer, and check a business’s standing with BBB before signing anything.
What to ask before you approve hail repair work
You don’t need to count and classify every dent yourself. A short list of questions gets you a clearer estimate:
- How many panels does the estimate cover, and what’s the dent count and size class on each one?
- Which panels are PDR, and which need fill-and-paint or replacement — and why?
- Is any panel aluminum or high-strength steel, and does the estimate reflect that markup?
- Is the estimate written for an insurance claim, an out-of-pocket repair, or both?
- If this is a claim, has the shop’s estimate been reconciled against the insurer’s own inspection?
