Portable ladders used to gain access to a roof or other elevated level must extend above the highest point by at least how many feet?

• A. 1
• B. 2
• C. 4
• D. 3

Answer: (D)

Ladders used to access a roof must extend above the edge to give you a secure handhold and a safe way to step onto the roof. The minimum extension is three feet above the highest point. This extra length lets you grab the ladder top while maintaining three points of contact as you transition onto the roof, which helps prevent slips or falls. If the ladder only extends one or two feet, there isn’t enough room to grip securely or to step onto the surface safely. Extending four feet is permissible, but the important point is meeting or exceeding the three-foot minimum.
