Hail damage cause-of-loss roof inspections in Colorado.
Was it hail, and which storm? Independent forensic roof inspections that separate hail damage from wear, manufacturing issues, and mechanical damage, with date-of-loss analysis tied to recorded storm data.
What a cause-of-loss inspection answers
Most hail disputes come down to three questions: is there hail damage, does it affect how the roof performs, and did it happen on the claimed date of loss? On the Front Range, where many roofs have been through more than one hailstorm, the third question is often the hardest.
Our inspection documents the physical evidence on every slope and ties it to the weather record, so each conclusion can be checked by the other side.
- Presence. Hail-caused fractures, bruises, and granule displacement, separated from look-alike conditions.
- Function. Whether damage reduces water shedding or service life, versus marks that change appearance only. Policy language controls coverage; we document the condition.
- Timing. Whether the damage is consistent with the reported storm or with an earlier or later event.
- Extent. Slope-by-slope counts that support, or do not support, a repair or replacement scope.
Hail damage and its look-alikes
Aging, blistering, foot traffic, and installation problems can resemble hail at a glance. These are the distinctions we document.
| Roof component | Consistent with hail | Consistent with wear or other causes |
|---|---|---|
| Asphalt shingles | Random impact marks with displaced granules, a fractured mat or soft bruise under the mark, concentration on slopes facing the storm | Blisters and pops, thermal cracking, uniform granule loss from age and UV, scuffs from foot traffic, manufacturing defects |
| Soft metals | Rounded dents and spatter marks on vents, flashings, and gutters, sized and oriented consistently with the storm | Ladder and tool dents, dents on faces the storm could not reach, oxidized marks predating the storm |
| Wood shakes | Fresh splits with sharp, unweathered edges and an impact mark at the split | Grayed, weathered splits and checking along the grain from wet and dry cycles |
| Tile, slate, and metal | Fresh fractures with clean edges, dents matching hail size and direction | Cracks with dirt or growth in the break, walking breakage, fastener and installation damage |
How we inspect a hail loss
Test squares and counts
Where it is safe, we lay out a 10 by 10 foot test square on each directional slope, count hail-caused damage, and photograph each square with a scale. Counts are reported slope by slope.
Collateral damage
Soft metals, condenser fins, window screens, siding, fences, and painted surfaces show hail size and direction, and help separate one storm from another.
Weather records
NOAA's Storm Events Database, National Weather Service local storm reports, CoCoRaHS observer reports, and radar-based hail swath reports. Radar estimates hail aloft, so we treat it as corroboration, not proof.
Date-of-loss indicators
Weathering and oxidation at fractures and spatter marks, prior inspection photos, historical aerial imagery, permit records, and prior claims when they are produced.
Samples and custody
When samples are needed, removal is coordinated with the parties, photographed before and after, labeled, sealed, and logged on a chain-of-custody record.
Repairability
Whether a repair can meet the manufacturer's instructions and local code, including brittleness of aged shingles and Class 4 requirements in Fort Collins and unincorporated Larimer County.
How an engagement works
Hail matters move faster when we see the claim file and the storm dates before we go on the roof.
Intake
Parties, property, date of loss, and deadlines. Conflict check before anything substantive.
Records
Claim file, prior photos and estimates, and the weather record for the property and the dates at issue.
Inspect
Test squares, collateral survey, measurements, and samples under chain of custody where agreed.
Report
Findings on presence, function, timing, and extent, with photos indexed to a roof diagram.
Testify
Deposition, appraisal panel, arbitration, or trial, with the field record as the exhibit set.
Built to be checked
- Slope-by-slope photo report with test square counts, scale references, and a roof diagram.
- Weather correlation summarizing recorded storm events, reported hail sizes, and their limits.
- Date-of-loss opinion stating what the evidence supports and where it cannot separate two storms.
- Scope recommendation for repair or replacement, with a line-item estimate on request.
- Rebuttal review of opposing inspection reports and carrier or contractor scopes.
Independence and disclosures
Our opinions follow the evidence. We do not take contingency fees on expert work, and we do not bid, sell, or perform roofing work on a property where we are retained as an expert, and we disclose any prior relationship with the property or parties at intake. Engagements are hourly or flat fee under a written retention agreement.
A CV and fee schedule are provided on request, along with any prior testimony disclosures the rules require., and reports are prepared to support Fed. R. Civ. P. 26 and C.R.C.P. 26 expert disclosures.
For hail matters we are retained by counsel, carriers, or appraisers and umpires. We do not handle claims for policyholders or act as a public adjuster.
We provide technical opinions, not legal advice.
Why timing drives Colorado hail disputes
The Front Range from Fort Collins through the Denver metro sees frequent damaging hail, and many roofs carry marks from several storms. Disputes often hinge on a policy change, a prior paid claim, or a roof replaced between storms.
High-altitude UV and freeze-thaw cycles age roofing faster than in many regions, which is why separating wear from hail matters as much as finding the hail. We work across Larimer, Weld, and Boulder counties, the Denver metro, and the mountain communities, where storm reports are sparser and the physical evidence carries more weight.

Hail cause-of-loss questions
Can you tell which storm caused the damage?
Often we can narrow it. We compare the physical condition of the marks, such as weathering, oxidation, and the freshness of fractures, with recorded storm dates, reported hail sizes, and prior photos. Where the evidence cannot separate two storms, the report says so.
What is the difference between functional and cosmetic hail damage?
Functional damage reduces a roof's ability to shed water or shortens its service life, such as fractured shingle mats or punctured metal. Cosmetic damage changes appearance only, such as shallow dents in metal panels. Policy language controls coverage; we document the condition so the parties can apply it.
Is radar hail data enough to prove a date of loss?
No. Radar estimates hail in the storm, not what reached a specific roof. We use NOAA Storm Events data, National Weather Service reports, and hail swath reports as corroboration alongside the physical evidence on the property.
Do you use test squares?
Yes. Where it is safe, we lay out a 10 by 10 foot test square on each directional slope, count hail-caused damage, and photograph each square with a scale. Counts are reported slope by slope.
Do you remove samples from the roof?
When needed and agreed by the parties. We photograph before and after removal, label and seal each sample, and keep a chain-of-custody log.
Who retains you for hail inspections?
Plaintiff and defense counsel, insurance carriers, and appraisers or umpires. We do not handle claims for policyholders or act as a public adjuster. Homeowners with recent storm damage should start with our storm damage page.
