Case Study

Hail Impact Damage

Independent assessment of hail storm damage on a multi-family residential property to determine the extent of impact.

Background

Following a reported hailstorm, a multi-family residential property required an independent assessment of potential damage. The team was retained to evaluate the roof covering and related building components to determine the extent of hail impact.


Investigation

A detailed site and roof inspection was conducted. Standardized test squares were used on the roof covering to identify and document hail strikes and wind damage.

Collateral building elements such as vents and flashing were examined for corroborating impact evidence. Surface oxidation and weathering were reviewed to establish the timeframe of damage.


Key Findings

Roof Covering

Extensive hail strikes documented within 10×10 test squares, exceeding typical repair thresholds.

Light Gauge Metal

Significant impact damage observed to flashing, vents, and other thin metal components.

Storm Correlation

Damage patterns consistent in size and scope with recently reported storms. Fresh spatter marks on oxidized surfaces matched the trajectory of the recent storm, confirming damage occurred during this event.

Outcome

The assessment confirmed roof covering and light gauge metal elements sustained substantial hail damage attributable to the recent storm. Replacement of the roof covering and repairs to associated metal components were warranted.

Takeaways

Objective field testing—such as test squares, collateral damage review, and spatter mark analysis—is essential in distinguishing hail impacts from age-related wear.

Aligning observed damage with recent storm data provides clarity on both the cause and timing of loss.
