Which type of ladder is noted as a roof ladder in the equipment inventory?

A roof ladder is specifically designed for working on sloped surfaces, such as roofs. Unlike other types of ladders, a roof ladder typically features a hook at the top, which allows it to be securely anchored to the peak of a roof. This design enables firefighters to maintain stability and safety while performing tasks at elevation, such as ventilation or rescue operations.

When assessing the other ladder types listed, none are specifically categorized as roof ladders. An extension ladder is primarily used for reaching higher areas and does not have the same specialized features as a roof ladder. An attic ladder is designed for accessing attic spaces and is usually smaller and more lightweight, limiting its application on roofs. A straight ladder, while versatile, lacks the specific design elements that make a roof ladder suitable for the unique challenges encountered when working on sloped surfaces. Therefore, recognizing that the 14 ft. roof ladder is built for this purpose clarifies why it is the correct answer.
