In today's world, there are hardly any technical limits to roof shapes. The only restrictions come from zoning plans, building regulations, and the processability of the chosen roofing material. Therefore, preventive fire protection at roof connections, penetrations, and in roof construction requires special attention. Preventing fire spread is a key protective goal in this component. This specialized book is aimed particularly at fire protection planners and experts, as well as carpenters and roofers. It provides foundational knowledge for classifying construction projects into legal building classes and allows for the determination of fire resistance duration requirements for a roof structure. The requirements for relevant components are addressed in a separate chapter.
