When using a ladder, how far must it extend above the roof edge?

• A. 1 foot
• B. 2 feet
• C. 3 feet
• D. 4 feet

Answer: (C)

When using a ladder to access a roof, it is standard practice that the ladder must extend at least 3 feet above the roof edge. This requirement is in place to ensure the safety of individuals who are transitioning between the ladder and the roof. The extension provides a secure handhold that allows a person to maintain their balance while climbing on or off the ladder, reducing the risk of falls or slips that could lead to serious injuries. The additional height enables the user to securely grasp the ladder while safely positioning themselves on the roof, which is particularly important as roofs can have uneven surfaces and various pitch angles. As a safety standard, this requirement helps to promote best practices in ladder use and fall prevention.
