Which of the following is NOT a risk factor for roofing work?

Clear sunny weather is considered the least risky condition for roofing work compared to high winds, lightning, and heavy snow. While sunny weather generally offers favorable working conditions in terms of visibility and dry surfaces, it does not present the same immediate dangers that the other conditions do.

High winds can cause instability and increase the likelihood of falls, while lightning poses a severe safety threat to workers on elevated structures. Heavy snow adds weight to roofs and can obscure hazards, such as potential structural integrity issues or slippery conditions, making it dangerous to work on roofs under such circumstances.

Understanding the risks associated with different weather conditions is crucial for ensuring the safety of roofing professionals, which is why clear sunny weather is not categorized as a significant risk factor in this context.
