How many rungs above the roof should a ladder be when laddering a roof?

When laddering a roof, the recommended practice is to extend the ladder 3-5 rungs above the roofline. This provides several advantages. First, having the ladder extended above the roof enhances stability and safety for firefighters when they are climbing down or transitioning from the roof back to the ladder. It ensures that there is enough ladder length for a safe grip, allowing the firefighter to maintain balance while stepping down.

Furthermore, this extended position allows for easier access and helps in the overall escape strategy should a situation on the roof become hazardous. The aim is to ensure that the ladder is securely positioned while still offering a safe and reliable means of egress. This 3-5 rung extension is a widely accepted standard in fire service training, making it crucial for safety and operational effectiveness when laddering a roof.
