What Happens During a PDR Hail Damage Estimate?

Why Hail Estimates Are Different From Looking at One Dent

Estimating repair for a single door ding is relatively straightforward: look at the dent, assess it, price the work. Hail damage is a different kind of problem.

A severe hailstorm can place dozens of dents across every horizontal and vertical panel of a vehicle. A roof alone can have 50, 80, or more individual impacts. Many of these are only visible under proper inspection lighting — they are hidden in ordinary ambient light, making a casual visual inspection unreliable as a basis for either a repair plan or an insurance claim.

A professional hail damage estimate is a methodical process. The technician goes through the vehicle systematically, working panel by panel, to identify and document the full extent of the damage before any repair begins.

The Role of Inspection Lighting

Specialized inspection lighting is fundamental to accurate hail damage assessment. PDR technicians use high-intensity reflection lights — often fluorescent or LED bar lights — that cast a uniform reflection across the panel surface. When viewed from the correct angle, distortions in the metal interrupt the smooth reflection line and become clearly visible.

This same principle applies when the technician works on repairs: the reflection lines serve as a real-time guide, showing where the metal is still distorted and when it has returned to a smooth surface.

In ordinary sunlight or indoor ambient light, many hail dents are nearly invisible. This is why insurance estimates prepared by adjusters in parking lots — without proper lighting equipment — often miss damage that only becomes apparent during professional repair. That gap between the initial estimate and the full scope of damage is a normal part of the hail repair process, handled through a supplemental claim.

Panel-by-Panel Assessment

A thorough hail estimate covers every panel that could have been exposed to the storm. This typically includes:

• Roof
• Hood
• Trunk or decklid
• All four doors
• Front fenders
• Rear quarter panels
• Pillars (A, B, C, D where applicable)
• Mirrors
• Any roof accessories (moonroof trim, antenna, rails)

For each panel, the technician is noting the number of dents, their approximate size distribution, their location on the panel, and their overall severity. This information forms the basis for the repair estimate.

Evaluating Dent Size and Severity

Not all hail dents are the same. Hailstones vary in size, and the angle, velocity, and surface conditions at the moment of impact all affect the character of the resulting dent.

The technician is evaluating several things for each category of damage:

• Size — larger dents require more work and have different characteristics than small ones
• Depth — shallow dents are generally more accessible for PDR; very deep dents may have stretched the metal
• Shape — rounded, bowl-shaped dents are more workable; dents with sharp edges or creases are more complex
• Paint condition over the dent — the most critical factor for PDR eligibility

Access Considerations

PDR requires physical access to the back of the damaged panel. Most exterior panels have access from behind — through interior door cavities, wheel well openings, or under hood/trunk areas. But some locations present challenges:

• Areas near structural braces or reinforcements inside doors
• Certain body line positions where tools cannot reach at the right angle
• Panels with complex contours
• Areas adjacent to factory undercoating or adhesive deadening material

When access is limited, the technician may be able to create access by temporarily removing interior trim panels, or may determine that a particular dent requires glue-pull techniques or another approach. In some cases, a dent in an inaccessible location may need conventional repair.

Previous Repairs and Paint Condition

Prior body work affects the current repair assessment. Body filler from a previous repair is not metal — PDR tools work on metal, not filler. Panels that have been repainted may also have thicker paint that behaves differently under PDR than original factory paint.

The technician will check paint thickness in areas where prior repairs are suspected, and factor that into the assessment. This is straightforward professional practice, not a reason to avoid the process.

Building the Repair Estimate

Once the inspection is complete, the estimate reflects the panel-by-panel findings: number of dents per panel, size categories, any additional labor for trim removal or access work, and whether any panels require conventional repair.

A professional PDR estimate for significant hail damage is a detailed document. If you receive an estimate that is a single line item or a single number with no breakdown, it is worth asking for more detail.

Insurance Estimate vs. Repair Estimate

Insurance adjusters and PDR technicians are assessing the same vehicle from different positions. An adjuster may be working quickly, in ordinary light, without the specialized tools needed to reveal all the damage. A PDR technician doing a formal estimate has inspection lights, experience with hail damage patterns, and a professional interest in identifying the complete picture.

The result is that professional repair estimates sometimes exceed the initial insurance estimate. This is not unusual and does not reflect poorly on either party. The supplement process exists to address exactly this situation: as additional damage is identified during professional inspection or repair, it is documented and submitted to the insurer.

What to Bring to Your Estimate

• Your vehicle — clean exterior makes inspection easier
• Insurance claim information if a claim is already open
• Any photos you took shortly after the storm
• Questions about the repair process or timeline

You do not need to have filed an insurance claim before scheduling a professional estimate. An estimate can be a useful first step in understanding the scope of damage, before or alongside the insurance process.
