2025 Convention Session: Forensic Insights into Roof Failures (Bjornson, Hasan)

Course Overview
This session was originally presented at the 2025 IIBEC International Convention & Trade Show in Orlando, Florida.  This course includes the following components:

• recording of the live session
• a summative assessment consisting of 10 multiple-choice questions
• two surveys required to claim continuing education credit

Description

This presentation will provide insights on forensic failures of roofs and how, given the changing climate and higher precipitation levels, these forensic failures are becoming more prevalent. Roof failures are a complex phenomenon that is primarily attributed to construction and design inadequacies. Deficiencies in roof detailing facilitate water entry, undermining the roof’s structural integrity and causing leaks and interior damage. Flashing issues, stemming from poor installation or maintenance, lead to water leakage at critical interfaces such as penetrations. Design flaws such as inadequate considerations for load distribution, water management, and adaptation to the local climate can lead to catastrophic outcomes. The inadequate integration of a roof with the broader building enclosure can also exacerbate these problems. These issues highlight the intricate challenges associated with roof failures, emphasizing the critical need for well thought out design and construction of roof features.
