Selecting the right reroof strategy requires balancing performance, risk and long-term building value. This course provides an overview of metal roof retrofit fundamentals, reviews key factors that should be evaluated before pursuing a retrofit project and examines the range of metal-over-metal (MOM) solutions available today. Attendees will assess the limitations and potential risks associated with roof coatings and TPO systems applied over existing metal roofs and learn how lifecycle cost analysis can help inform roofing decisions beyond initial installation costs. The course will better equip participants to evaluate reroofing options that align with the performance goals and lifespan expectations of their projects.
