What type of ladder is designed specifically with hooks to secure it to a rooftop?

The ladder designed specifically with hooks to secure it to a rooftop is known as a roof ladder. Roof ladders feature a set of hooks that can be securely fastened over the peak of a roof, providing stability and safety for firefighters working at height. This design is particularly important in firefighting, as it prevents the ladder from slipping or sliding off the roof while personnel are operating on its surface.

In contrast, extension ladders are primarily used for reaching high places by extending their length but do not have the specialized hooks. Folding ladders are versatile and compact but are not specifically designed for roofing applications. Combination ladders can serve multiple purposes but also lack the unique hook feature that characterizes roof ladders. Thus, the roof ladder is the optimal choice for providing secure access to rooftops during firefighting operations.
