A roof plan primarily focuses on the layout and shape of the roof, including details such as the type of roof covering, roof drainage systems, and items that penetrate or are mounted to the roof. While it may indicate the placement and configuration of structural components, a detailed view of trusses or rafters is generally found in floor plans or structural drawings rather than in the roof plan itself. The roof plan is more concerned with the overall design and functional aspects of the roof rather than the internal structural elements like trusses or rafters, which are typically represented in separate types of drawings. Hence, it is appropriate to say that the roof plan does not typically show the trusses or rafters.
