How should you secure a ladder when working on a roof?

Securing the base of the ladder is critical for maintaining stability and preventing accidental tipping or sliding while working on a roof. A properly secured base means ensuring that the ladder is positioned on a flat, stable surface and possibly using additional materials, like ladder stabilizers or outriggers, to provide extra support and minimize the risk of the ladder moving.

When the base is secured, it allows the user to climb the ladder safely and maintain their balance while working at height. This practice is essential to prevent falls, which can result in severe injury. Although anchoring the top of the ladder or tying off both ends might seem secure, these methods do not address the foundational stability required when working at heights. Additionally, while scaffolding can provide a safe working platform, it is not a direct method to secure a ladder itself for the task at hand.
