How much should a plumbers extension ladder extend above the roof when using one?

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

Answer: (C)

Having enough ladder extension above the roof edge matters because you need a solid handhold to safely transition from the ladder to the roof. Extending the ladder three feet above the roofline provides a comfortable grip and a stable place to step onto the roof, reducing the chance of slipping or losing balance as you climb up or down. This 3-foot extension is the standard guidance used in safety training, giving you enough clearance to grip the top rung and maintain three points of contact during the transfer. If the ladder doesn’t extend that far, there isn’t a secure handhold for stepping onto the roof, which increases fall risk. So, extending three feet above the roof is the best practice.
