We differentiate internal water leak claims from external ones because their causes and coverage differ significantly. External water leaks typically result from flooding events—such as those seen after Hurricane Harvey in 2017—and are generally handled as FEMA flood claims, which are not covered under standard business or homeowner insurance. In contrast, most policies cover water damage resulting from failures of internal water systems. If a system within your home or business malfunctions and causes water damage, that event is likely covered. Similarly, if interior damage is caused by a storm that creates an opening, the claim is usually covered but falls under wind or named storm coverage.
