Most coverage gaps come from a standard policy meeting a situation it was not written for. This asks a few questions about your circumstances and points to the ones worth checking in your own documents.
This does not review your policy and cannot tell you whether you are covered. It has never seen your documents. What it does is narrow a long list of possible gaps down to the ones that apply to your situation, so the conversation with your insurer is specific rather than general.
What to do with the result
Each item names the thing to look for and where to look. Take the list to your declarations page first, and then to your insurer or agent for anything you cannot find. A specific question — "does my policy include water backup coverage?" — gets a checkable answer in a way that "am I fully covered?" does not.
This is general education, not advice. Insurance law and claim rules vary by state and change over time. Nothing here is legal, financial, or insurance advice for your situation, and reading it does not create any professional relationship. For your specific case, consult a licensed professional in your state or contact your state Department of Insurance.
