Resilient buildings are engineered to endure significant weather events and maintain functionality afterward. A critical element of any resilient structure is its roof system. While a roof's primary function is to protect a building from daily weather, there's a growing demand for enhanced resilience. Evolving policies and increasing owner expectations are driving the need for roofs capable of withstanding more extreme conditions. This presentation will delve into the principles of designing new resilient roof systems and explore strategies for upgrading existing ones. We will cover key considerations such as material selection, system design, and advanced drainage solutions. The aim is to equip attendees with the knowledge to create roof systems that offer superior protection, minimize post-event disruption, and contribute to the overall long-term viability of buildings in the face of increasingly unpredictable weather patterns.
