Battling the Perfect Storm: Designing Roofs to Withstand Nature’s Worst

Description 
As the saying goes, when nature is at its worst, buildings need to be at their best. Roofs are designed to keep weather out. As weather gets more extreme, roofs are being asked to withstand more. During this presentation, you will learn about the new wind requirements in ASCE 2022, ways to design roofs to resist high winds, best practices for designing for very severe hail, and ways to manage water from large rain events. 

Learning Objectives

1. Apply the foundational elements of ASCE 7 when determining wind loads acting on a building.

2. Recognize the code requirements for edge metal and understand its importance for overall wind resistance. 

3. Understand best practices for designing a roof to resist very severe hail.

4. Evaluate options for managing water from large rain events, including tapered insulation and water retention and detention.
