Under Extended Coverage, what condition must be met for interior damage to be covered?

To qualify for coverage under Extended Coverage, the key condition is that the exterior of the structure must be damaged first before any interior damage will be covered. This stipulation is designed to ensure that the damage resulted from a direct cause, typically related to certain perils like windstorm or hail, which would compromise the exterior integrity of the building. The rationale behind this requirement is to limit claims to situations where there is a clear and direct link between the exterior damage and the resulting interior damage, thus protecting against situations where interior damage could occur independently of any broader peril affecting the structure.

This approach prevents claims for internal damages that could arise from other unrelated issues, ensuring that the insurance covers specific, intentional scenarios that align with the risk assessment of the policy. The other options do not align with this requirement, as they either focus on conditions unrelated to the cause-effect chain of damage or impose constraints that do not reflect standard policy terms for Extended Coverage.
