What is a critical step before starting work on a roof?

Before commencing work on a roof, inspecting the ladder and roof integrity is crucial for several reasons. Ensuring that the ladder is in good condition and securely positioned helps prevent falls when accessing the roof. Additionally, assessing the roof's integrity guarantees that it can safely support the worker's weight and that there are no hidden hazards such as weakened sections or moisture damage. This step is vital for maintaining safety and preventing accidents while working at heights.

While confirming the weather conditions is important to avoid working in adverse conditions, it does not directly relate to the immediate physical safety measures that need to be checked before starting the job. Wearing appropriate footwear is essential for grip and support, but casual shoes would not provide the necessary safety features required for roofing tasks. Simply securing the ladder, while important, does not encompass the comprehensive safety checks needed for both the ladder and the roof structure. Thus, a thorough inspection of both the ladder and the roof is the key step before starting work, ensuring a safer working environment.
