Permanent devices that secure the tip of a roof ladder to a pitched roof are called:

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

Answer: (A)

Securing the top of a roof ladder on a pitched roof requires a fixed, reliable anchor. Roof hooks are designed for this purpose: they attach to the ladder tip and hook over the roof ridge or edge, creating a permanent, stable connection that prevents the ladder from slipping while you work. This makes them the best choice for a top securing device that stays in place on the ladder. Other options don’t serve the same function: tie-rods are used for bracing or securing to structural members in ways that don’t provide a secure top latch over the roof; channels are parts of the ladder’s construction rather than anchors to the roof; rollers are mobility aids and would not keep the ladder in place.
