Asphalt shingle roof with hail impact marks and hailstones after a storm

Hail and wind expert witness

Hail and wind damage weather expert for property claims

Whether hail or damaging wind reached the property, how large or strong it was, and on which date, using radar, storm reports, and observations.

Hail and wind claims are among the most frequently disputed property claims. The questions are rarely whether a storm occurred in the region, but whether it produced damaging hail or wind at the specific roof in question and on the date claimed.

Dr. Banks has built storm-history pipelines from NOAA and SPC records and uses radar-derived hail and wind products to evaluate events at the address level, including searching an entire policy period when the date of loss is unknown.

Questions a forensic meteorologist can answer

  • Did hail fall at the property, and how large was it?
  • Which dates in the policy period had damaging hail or wind?
  • What was the likely peak wind gust at the site?
  • Was a tornado or downburst responsible?
  • Is the claimed date of loss consistent with the weather record?
  • Could the damage be from an older event?

Records and data used

  • NEXRAD radar and MRMS maximum estimated hail size (MESH)
  • SPC storm reports and NOAA Storm Data
  • NWS damage surveys and local storm reports
  • Surface observations and mesonet wind gusts
  • GOES satellite for storm evolution
  • Historical hail and wind climatology for the location

Typical matters

  • Residential and commercial roof claims
  • Date of loss disputes and late-reported claims
  • Appraisal and umpire proceedings
  • Bad-faith and coverage litigation
  • Contractor and public adjuster disputes

Frequently asked questions

Are radar hail estimates reliable?

Radar-derived hail estimates such as MESH are useful but imperfect. They are most reliable when combined with ground reports, observations, and storm structure analysis. A good report explains those limits instead of relying on a single radar product.

Can you analyze several possible dates of loss at once?

Yes. A date of loss study reviews the full history at the property for the policy period, ranks the candidate events, and explains the evidence for each one.

Have a weather question in a case or claim?

Initial consultations are free. Share the date, location, and the weather issue in dispute, and Dr. Banks will tell you what the record can and cannot support before you retain.
