# The hail dimple mapping, and why it gets written out of the scope

Hail on a coach or box roof gets acknowledged and then priced as one lump line. The dimple map is what converts hail into hours, and it is why a $1,500 allowance and an $18,000 scope describe the same roof.

## A hail acknowledgment is not a hail scope

The most expensive belief on a hail file is that agreement settles it. Someone looked at
the roof, said yes, that is hail, and opened the claim. The owner reads that as coverage
established and stops documenting. Coverage was established. Quantity was not, and on a
hail claim quantity is the entire number.

Hail is priced from a map. On passenger cars the industry has a settled instrument for
this: a matrix that records, per panel, how many dents fall into each size class, and
converts those counts into repair hours. It is unglamorous and it works, because two
people can look at the same matrix and arrive at similar hours without arguing about
adjectives.

That instrument thins out badly above a certain vehicle size. A matrix row exists for a
hood and a roof skin on a sedan. No row exists for 340 square feet of aluminum coach
roof, a TPO membrane over decking, a molded fiberglass cap, an air conditioner shroud, or
a box truck roof with a translucent panel in it. When the row does not exist, the estimate
reaches for a lump allowance instead, and a lump allowance is a guess wearing a number.

## The shape of a hail scope that is going wrong

You can read this off the sheet in about four minutes. One line saying hail damage repair,
one figure beside it, no panel breakdown underneath it. No column for dent count. No
column for size class. That is the signature, and it is not evidence of anyone behaving
badly. It is what a template produces when the vehicle falls outside the population the
template was built from.

Next, look at the photograph set attached to the file. Four wide shots from ground level
and two roof shots taken from the top of a ladder at a shallow angle mean the roof was
observed rather than measured. Hail dimples in aluminum or gelcoat are shallow and they
disappear under flat overhead light. If nobody used a light source at a low angle, the
photographs genuinely cannot show what is there, and a reviewer working from them is not
withholding anything.

Three more absences matter. There is usually no line to remove and reinstall the air
conditioner shrouds, vents, antennas and solar so the skin underneath can be seen and
worked. There is often no refinish line written from measured surface area. And the loss
description frequently reads storm damage with no event date, which is the field that
later decides whether a dimple belongs to this claim or to a prior one.

## Why can one San Gabriel Valley yard hold three separate storms?

Hail is rare enough in Los Angeles County that owners treat it as a single memorable
event. The vehicles do not agree. Small hail rides in on late winter and spring
convective cells that build over the Puente Hills and the eastern end of the valley, and
a yard along the SR-60 corridor can take a five minute cell in March, another the
following February, and a third two years later, with nobody writing any of it down.

A fleet unit that parks outdoors accumulates all three. That is the structural problem on
a valley hail claim, and it is exactly the pattern behind separating occurrences. Each
storm is its own event with its own date and its own deductible. A single estimate that
covers dimples from three cells will usually have most of its scope questioned, because
whatever cannot be tied to the reported date has nothing supporting it in the file.

There is a second local effect. Because hail work is uncommon here, the estimating
templates, the local labor time assumptions and the available paintless repair capacity
all see far less of it than a Texas panhandle market does. Nothing improper follows from
that. It simply means the burden of producing a measured map sits with the shop and the
owner rather than with a routine that already exists.

## Raking light, a chalk grid and a dent gauge

Four things turn a roof into a document a reviewer can act on. First, light. A work light
held eight to twelve inches off the surface, aimed almost parallel to it, throws every
dimple into shadow. Photograph along that light, not across it. This single change is the
difference between a photo set that proves nothing and one that proves the count.

Second, a grid. Chalk or low tack tape divides the roof into one foot squares, and each
square gets photographed with an identifying mark visible. Third, a size reference in
every frame: a dent gauge, a coin, a tape measure laid flat. Counts and sizes with a
reference in frame are verifiable. A statement that there are hundreds of dimples is not,
and it will not survive review.

Fourth, dates. Screenshot the public weather record for the cell you are claiming, with
the date and the location visible, and put it in the file next to the map. If you have
casual roof photographs from before that date, even a phone snapshot taken while cleaning
gutters, they are worth more than anything else you own, because they are the only
material that separates this storm's dimples from the last one's.

## What separates a lump allowance from an hours based scope?

Arithmetic, and nothing else. Hail damage roof repair spans $1,500 to $18,000 plus at 10
to 80 plus hours, and that band is wide because it covers everything from a dozen
dimples in a single aluminum panel to a roof that needs full replacement at $3,500 to
$18,000 plus. Dent removal and repair runs $500 to $6,500 at 3 to 30 hours. Aluminum
roof repair runs $800 to $6,500. Which of those the roof actually needs is a counting
question.

The hours are where a lump allowance loses money quietly. At the posted body and paint
rate of $210 per hour, an allowance twenty hours short of the work is a $4,200 gap before
paint materials, which bill at $55 per paint hour on top. None of that is visible on a
sheet that only carries one figure, because there are no hours on the sheet to compare
against.

Getting to a real number costs one priced hour. A collision teardown estimate is 1 hour at
$210, an insurance claim damage assessment runs $285 to $1,200 at 1 to 5 hours, and both
are credited against an authorized repair. What you receive is a mapped roof with counts,
sizes and photographs, which is the form a supplement has to take to be approved on first
review.

## Betterment lands on roof age unless condition sits in the file

Expect a betterment or condition adjustment discussion on any roof over five or six years
old. Betterment is the principle that a new component on an older vehicle leaves the owner
ahead of where the loss found them, so the owner contributes the difference. It is a
feature of the coverage, not a position anyone took against you, and on a roof it can be a
large percentage.

What makes it expensive is how it is commonly calculated. Age is the one input always
available, so age is what gets used. Condition before the loss is a better input and it is
almost never in the file, because nobody photographs a sound roof. A roof that was
resealed eighteen months ago and a roof that has never been touched are the same roof to a
calculation that has only a model year to work with.

So supply the missing input. Dated reseal and inspection invoices, spring photographs with
the vents, seams and shroud visible, and any moisture readings taken before the storm.
Then ask that pre loss condition be weighed alongside age. Condition evidence is what moves
a betterment figure. Age alone gives a reviewer nothing to work with in either direction.

## Map the roof before the reinspection is scheduled

Order matters more than effort here. Map first, submit second, schedule the reinspection
third. A reviewer holding a gridded photo set with counts and a dent gauge in frame can
frequently approve without another site visit, and every avoided visit is a week off the
calendar. Moderate body work runs 1 to 3 weeks of shop time once approved, and a full
refinish runs 4 to 10, so the approval calendar is usually the longer half of the job.

If the vehicle is sitting in a per diem yard while any of this happens, move it. Storage
accrues daily, it produced no repair, and it is the line examined hardest at settlement.
Name the repairing facility on the first call rather than letting the assignment route by
default, and offer two specific dates for any inspection instead of asking when someone is
available.

Bring the unit to us and the mapping happens with a lift, a light bar and controlled
lighting rather than a ladder in a parking lot. All of it happens at 23281 La Palma Ave in
Yorba Linda, 18.4 miles from Hacienda Heights, 24 to 38 minutes via SR-60 west to
Fullerton Rd or SR-60 to SR-57 south to SR-91 east. Call (949) 799-3387 with the claim
number, the date of loss and the roof material.
