Field Investigation and Data-Driven Evaluation of Roofing Systems Following a Major Wind Event

This presentation highlights a comprehensive field investigation and data-driven evaluation of various roofing system performance following the impact of Hurricane Helene and Hurricane Milton. The purpose of this study is to assess the vulnerability and failure mechanisms of various roofing assemblies- including low-slope membranes, concrete roof tiles, shingle roofs and flashing components-under extreme wind pressures and wind-driven rain. The investigation was conducted as part of a post-event forensics assessment of over 30 residential structures, focusing on the relationship between installation practices, material performance, and environmental exposure. 

Attendees will gain an understanding of how construction detailing, material selection, and installation quality influence roof performance during hurricanes. The presentation will also demonstrate practical methods for conducting post-event forensics investigations, including data collection, documentation, and correlation with wind speed and pressure exposure. Participants will learn how to apply a data-driven framework to assess system vulnerabilities and recommend targeted improvements. Expected outcomes include enhanced technical knowledge of building enclosure (roofs), improved ability to interpret field data for performance evaluation, and an increased awareness of how forensic findings can inform future design standards, inspection protocols, and code development in hurricane-prone regions such as Florida.
