Hail Impact Damage
Overview
Following a reported hailstorm, a multi-family residential property required an independent assessment of potential damage. Our team was retained to evaluate the roof covering and related building components to determine the extent of hail impact and provide objective findings.
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, while collateral building elements such as vents and flashing were examined for corroborating impact evidence. Surface oxidation and weathering were also reviewed to help establish the timeframe of the damage.
Initial Findings
Roof Covering: Extensive hail strikes were documented within 10′ x 10′ test squares, exceeding typical repair thresholds.
Light Gauge Metal: Significant impact damage was observed to flashing, vents, and other thin metal components.
Storm Correlation: Damage patterns were consistent in size and scope with recently reported storms affecting the coverage area. Fresh spatter marks on oxidized surfaces matched the trajectory of the recent storm, confirming that the damage occurred during this event.
Outcome
The assessment confirmed that the roof covering and light gauge metal elements sustained substantial hail damage attributable to a recent storm. Replacement of the roof covering and repairs to associated metal components were warranted.
Lessons
Objective field testing—such as test squares, collateral damage review, and spatter mark analysis—is essential in distinguishing hail impacts from age-related wear. By aligning the observed damage with recent storm data, the investigation provided clarity on both the cause and timing of loss.
