Permanent, curved, spring-loaded metal devices that secure the tip of a roof ladder to a pitched roof are:

• A. Tie-rods
• B. Roof hooks
• C. Channels
• D. Rollers

Answer: (B)

On a pitched roof, the top of the ladder needs a secure anchor to prevent sliding and tipping as you work. Roof hooks are designed for this purpose. They are permanent, curved, spring-loaded metal devices attached to the ladder tip that hook over the roof edge and apply tension to hold the ladder firmly in place on a slope. This setup provides a stable point of contact so you can climb and operate with less risk of the ladder shifting. Other devices have different roles: tie-rods stabilize the ladder from the base or between sections, not the tip on the roof; channels and rollers serve other functions in the ladder system and do not provide the same secure roof attachment.
