1 foot

2 feet

3 feet

When using an extension ladder to access a rooftop unit, it is important for safety and stability that the top of the ladder extends at least 3 feet beyond the point of support. This extra height provides a secure handhold when transitioning from the ladder to the roof, minimizing the risk of slipping or losing balance. It ensures that the ladder is stable and that the person climbing has sufficient leverage to reach the roof safely. The 3 feet extension is a standard safety guideline that helps prevent accidents by allowing for proper dismounting procedures. Proper ladder setup is crucial for maintaining safety when working at heights, making this guideline essential to effective ladder use in such scenarios.
