What is the typical length range for roof ladders?

The typical length range for roof ladders is between 12 to 18 feet. This length is optimal for providing access to the roof of a structure while remaining manageable for firefighters to deploy and maneuver. Roof ladders are designed to extend high enough to reach roofs of average residential buildings and commercial structures, which typically fall within this height range. The length allows for sufficient reach to ensure firefighters can safely access and work on roofs during operations like ventilation or firefighting. The stability and angle of such ladders are also suited for working in confined or complex environments typically found in firefighting scenarios.
