Which of the following is NOT a covered peril for collapse under a commercial property policy?

In the context of a commercial property policy, a peril is an event that may cause damage to the property and is typically covered by the insurance. When considering collapse as a covered peril, it’s important to recognize which situations are typically included and which are not.

The breakage of building glass, hidden decay, and the weight of rain on a roof are generally recognized as perils that can contribute to collapse in some form. For instance, hidden decay refers to deterioration that isn’t immediately visible but can compromise structural integrity, thereby making collapse more likely. Similarly, excessive weight from rain accumulation can put significant stress on rooftop structures, leading to potential collapse.

In contrast, volcanic eruption is an event that generally falls under the category of catastrophic natural disasters. While an eruption can indeed cause significant property damage, it typically does not directly relate to the concept of collapse as it is understood in the context of commercial property policies. Therefore, volcanic eruption would not typically be covered under the collapse provisions of such a policy. This makes it the correct choice for identifying which peril is NOT covered for collapse under commercial property insurance.
