Mosaic Reports

A hail damage report for a single address: what fell, when it fell and how hard. Measured on the ground where a Tessera stands, ground-trained by Hailios Fusion AI where one doesn’t, and labeled which is which. A report an adjuster can put in the file and a contractor can stand behind.

What makes this one different

There might already be a hail report in the file. This is the one built on measurement.

The first question to ask of any hail report: what does it actually know, and what is it guessing at?

Everything a Mosaic report says about the moment of impact is either measured by an instrument at the property or ground-trained by Hailios Fusion AI, a model trained on years of Tessera measurements and still training. It doesn’t need a sensor in the same storm to get it right, and the report says which is which, line by line. A radar-only report can’t make that distinction: it has nothing on the ground to make it against.

  1. 01

    It is about your property, not the storm’s footprint

    Most hail reports are a storm footprint with an address dropped on top. This one starts at your property, whether that’s one roof or a site drawn across many square kilometers, and reports what happened inside it.

  2. 02

    It can say no hail fell

    Radar can’t return a clean negative; it can only say the storm was probably nearby. Mosaic can say no and stand behind it: measured where a Tessera stands, ground-trained everywhere else. No hail is data, too.

  3. 03

    It says which numbers were measured

    Field by field, measured or ground-trained, with the confidence stated in plain language on page one. Nothing is quietly upgraded from estimate to fact.

    More ↓

  4. 04

    It states stone size as a floor, then the most likely size

    A measured floor where a sensor stands, never inflated, and beside it the size the storm most likely reached, labeled as modeled. Both survive a reinspection; neither is passed off as the other.

RADAR INFERS. WE MEASURE. THAT SENTENCE IS THE ENTIRE DIFFERENCE BETWEEN TWO DOCUMENTS THAT LOOK IDENTICAL FROM ACROSS THE ROOM.

The unit of work

Your property is the unit of work

Radar describes a storm in pixels, and one pixel can cover a whole neighborhood: every roof inside it gets the same answer. A Mosaic report starts from your property instead, one roof or a site outlined across many square kilometers, and drills in closer than a radar pixel alone: measured where a Tessera stands, ground-trained by Hailios Fusion AI where one doesn’t, and labeled which is which.

Report anatomy

What’s in a Post-Event Report

A Post-Event Report answers one question: what happened at this property during this event. Page one says what was measured, what was ground-trained and how sure we are, in plain language, before anything else. These are the fields; the values are your event’s.

AddressThe property itself, one roof or a site’s drawn outline, rather than a ZIP code or a county.
Event windowThe date, with the time the first impact landed and the last one stopped.
Map and trackWhere the storm came from, how it crossed the property and where it went.
Impact countWhere a Tessera stands, how many stones struck it over that window: the raw tally, before anything is interpreted.
Impact energyKinetic energy delivered per impact and across the event: the reading that tracks damage most closely.
Impact concentrationHow densely those impacts fell — the difference between a scattering of stones and a barrage.
DurationHow long the property spent under falling ice. Two events with the same peak are not the same claim.
Maximum diameterWith a sensor on site, the largest stone it caught: a measured floor, never inflated. Without one, ground-trained by Hailios Fusion AI and labeled so.
Most likely diameterModeled outward from that floor using every data point around the site, and labeled as modeled.
Measured vs ground-trainedWhich figures come from an instrument on the property and which from Hailios Fusion AI, trained on years of Tessera measurements, labeled field by field.
EvidenceWhat the finding rests on, stated plainly, and nothing hidden when it points the other way.
ConfidenceHow sure we are, in plain language, on page one — not buried in an appendix nobody opens.
StatusPreliminary as soon as the event is detected, then final.
FormatA PDF for the file, and structured data with the same values for your systems.

EVERY FIELD SAYS HOW IT WAS KNOWN: MEASURED, GROUND-TRAINED OR MODELED.

On stone size

Maximum stone size is a floor, not a guess.

AT LEAST THIS BIG: MEASURED. MOST LIKELY THIS BIG: MODELED. NEVER BLURRED TOGETHER.

Stone size is the number everyone reaches for and the hardest one to defend. Radar derives it indirectly and publishes a point estimate with no accuracy statement attached, which is why two vendors can hand an adjuster two different sizes for the same storm and neither can be falsified.

We start somewhere else: with measurement. With a Tessera on site, the floor is the largest stone it caught, and it is never inflated: stones of at least this diameter fell here. Across our multi-sensor sites, neighboring sensors differ by 15% on average, so the floor sits close to the truth. Without a sensor on site, the maximum is ground-trained by Hailios Fusion AI, trained on years of Tessera measurements, and the report labels it that way, field by field.

From there the report models outward, using every data point around the site, and states the most likely size beside the measured one, with its certainty, labeled as modeled. You get the number that survives a file review, a reinspection and a dispute, and the best estimate of what the storm actually did, without one being passed off as the other.

Impact energy and impact concentration sit alongside both: measured where a Tessera stands, ground-trained where one doesn’t, and they’re what correlates with damage to a roof, a panel or a car.

The answer radar can’t give

“Nothing above threshold fell here that day” is a finding, not a failure.

77% fewer false positives than radar models · scored against the ground

Radar can’t say no. It can only say the storm was probably somewhere nearby, which is what it also says when nothing happened. Where a Tessera stands, the no is measured. Everywhere else, Hailios Fusion AI answers it, trained on years of ground measurements that include every time nothing fell. Scored against the ground, it reports 77% fewer false positives than radar models: 77% fewer times it says hail fell where none did. That gap is where a great deal of money leaks.

A no-hail reading protects carriers from claims for damage that predates the storm or never happened. It protects honest contractors from driving three hours to a roof that was never hit, and from putting their name to a claim that will not hold. And it lets a site team skip an inspection they never needed.

So a no-hail result is a full report, delivered like any other, with the same confidence statement on page one. You are not paying for a yes. You are paying to stop arguing.

NO HAIL IS DATA, TOO. NOTHING ABOVE THRESHOLD FELL AT THIS ADDRESS ON THAT DATE. STILL EVIDENCE. STILL FILED.

Who it is for

Four people, one document

A hail report gets read by more than one person, and each of them asks it a different question. It has to answer all four without being rewritten for any of them.

Adjusters

“Was there a covered peril at this risk on the date of loss?”

A document that goes in the file and holds up when the file is reviewed.

Contractors, restoration & PDR

“Is this roof worth a claim, or worth a conversation?”

Evidence before the ladder comes off the truck — and before a reputation is attached to it.

Claims managers

“Which of these notifications are real?”

The same report across a book of losses, so triage stops being a coin toss.

Site & asset owners

“Do we send a crew out, and where first?”

What hit each site, from a single roof to a utility-scale solar farm, measured where a Tessera stands, so the inspection goes where the damage is.

Coverage

Measured where we are. Ground-trained where we aren’t.

Where a Tessera stands, the report says measured. Everywhere else, Hailios Fusion AI answers, trained on years of Tessera measurements, and the report says ground-trained, with its confidence stated on page one. The label is never quietly dropped. Europe and Australia have years of measured record too, and training Fusion AI on it is the next step.
