Flood insurance typically needs to be purchased in addition to a homeowners Insurance policy. More importantly, the term flood has a specific definition that’s often confusing for most people. A flood is when water from an existing water source, like a lake, rises up and enters the property. Usually when property owners see water in the property they’ll say, “my house is flooding!” Actually, this is water damage and the water intrusion is likely from a broken pipe or roof leak. This would not be a flood claim, but rather a broken pipe or roof leak claim.
