Factual Economics and markets

Roof inspection, which involves a person climbing up on a roof and taking notes, is a fairly dangerous job.

Mostly true True in substance, wrong in a detail.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

What would count as true or false

The claim is about degree ('fairly dangerous'). True: occupational safety data or authoritative industry sources show that climbing roofs for inspection, as insurance adjusters or inspectors do, carries a notable risk of serious injury or death from falls. Examples: BLS Census of Fatal Occupational Injuries data on roof falls, OSHA guidance, or insurance-industry safety reports describing falls and injuries among adjusters doing roof inspections as a recognised hazard above typical office or field work. Mostly true: the risk is real and recognised but moderate, e.g. well below roofers yet clearly above average. Mixed: the evidence is ambiguous on whether the risk is materially elevated. Mostly false: injuries happen but the data show risk close to ordinary occupational levels, and the claim overstates it. False: the data show roof inspection for insurance carries no meaningful elevated risk.

    “Roofers and painters were the most at risk to suffer nonfatal falls to a lower level in 2016.

Their rates far exceeded the rate for all workers combined of 5.1 cases per 10,000 full-time workers.”

    “An insurance adjuster was injured while performing the specific task he was hired to do: identify and distinguish preexisting roof damage from storm damage.”

Reasoning

BLS and peer-reviewed sources show that working on roofs carries a sharply elevated fall risk: roofers had a nonfatal fall-to-lower-level rate of 86.9 per 10,000 full-time workers, against 5.1 for all workers (E1), and falls accounted for 76% of roofing-industry deaths in 2003-2009 (E2, E6). Fatality investigations and court records describe an insurance claim adjuster killed falling from a roof during a claim assessment (E8), an estimator killed while inspecting a roof (E9), and an adjuster injured during a roof damage inspection (E11), so the hazard is real and recognised for inspection work. None of the evidence gives fall rates for adjusters or inspectors specifically. That supports "fairly dangerous" without measuring how much riskier the job is.
