NAFEForensic paper
A 2025 forensic engineering paper on separating genuine wind damage on residential roofs from installation defects, mechanical damage and age-related deterioration, aimed at making wind assessments repeatable rather than impressionistic.

Azzi, Vutukuru and Matus take on the problem that follows every hurricane season: telling wind damage apart from the wear, manufacturing variation and prior repair that a roof already carried. The paper works through the mechanisms by which wind actually lifts and breaks residential roof coverings, and what each mechanism leaves behind as evidence.
Why a contractor cares. It is the difference between pointing at a lifted tab and explaining the load path that lifted it. The second survives scrutiny; the first invites a denial for pre-existing condition.
Why a public adjuster cares. Carriers routinely attribute storm damage to age or installation. Forensic literature describing what wind uplift specifically looks like is the counterweight, and it carries the authority of a peer-reviewed engineering journal rather than a contractor's opinion.

A six-year field study of 729 residential hail-strike inspections by EES Group, correlating bruise counts against hailstone size, roof pitch and the elevation's orientation to the incoming storm. Useful when arguing why one slope shows damage and another does not.

Reports the second RICOWI hailstorm investigation, in which seven teams inspected more than 100 roof systems after the May 24, 2011 Dallas/Fort Worth storm to document how different roofing products — including impact-resistant products — performed against substantiated hail sizes.
