Why should inspectors avoid walking on insulated roofs?

• A. The inspector may damage the insulation
• B. The insulation may contain hazardous substances
• C. The roof plates may not support the inspector's weight
• D. The inspector may cause water-collecting indentations

Answer: (C)

Inspectors should avoid walking on insulated roofs primarily because the roof plates may not support the inspector's weight. Insulated roofs can be designed to distribute loads differently than traditional roofing systems, and if the structure is not adequately reinforced or if it has deteriorated over time, stepping on it could lead to structural failure. This could result in serious injury to the inspector and damage to the roof itself, which can be costly and lead to additional inspections or repairs. Moreover, the other options pose valid concerns but are not the primary reason for avoiding walking on insulated roofs. While damage to insulation can occur, the more immediate risk is the structural integrity of the roof underfoot. The potential presence of hazardous substances in the insulation is a consideration, but it is primarily a safety concern when doing inspection work, rather than a reason to avoid walking on the roof itself. Water-collecting indentations can indeed be a concern, but this results from improper weight distribution or existing issues and is secondary to the immediate concern regarding safety and weight support.
