When a building is a symbol of culture and history, protecting it from the elements and extending its lifetime is a big responsibility. This presentation delves into three distinct historic project case studies, each underscoring the critical collaboration required between the roof system manufacturer and the design team for a successful outcome. Each project utilized a unique roof assembly solution tailored to its specific needs. We will examine the decision-making process, including how durability and aesthetics were evaluated for the chosen roof assembly. Attendees will gain insight into the rationale behind each system selection and learn about the specific installation methods employed.
Ultimately, this session will equip attendees with practical guidance for both preserving existing, original roof assemblies and seamlessly integrating new, resilient solutions that honor the historic aesthetics of their projects.
