Standard homeowners insurance policies usually cover structural damage on your property. This includes your foundation, ceiling, flooring, roof and more. Your policy protects these structures under dwelling coverage in the event of unexpected damage.
Keep in mind that you are expected to do the necessary maintenance on your home. This means that general wear and tear damages are not covered by your policy. However, if you can make your case, you can get away with getting coverage on wear and tear damage if you can prove that the damage was completely invisible.
