When you purchase a home insurance policy, there are some basic disasters that are covered by the policy. These include damage caused by fire or lightning, windstorm or hail, explosion, riot or civil commotion. Also included are damaged caused by aircraft, smoke, vandalism or mischief, theft, volcanic eruption.
Certain policies also include loss due to falling objects, weight of ice, snow or sleet, accidental discharge or overflow of water or steam from within a plumbing, heating, air conditioning or automatic fire protective sprinkler system, or from household appliances.
However, flood coverage and earthquake coverage have to be purchased separately. Flood coverage can be purchased directly from your homeowners insurance agent. You can get replacement cost coverage for the structure of your home, but only actual cash value coverage is available for your possessions. Flood insurance is available for renters as well as homeowners.
Earthquake coverage can be a separate policy or an endorsement to your homeowners or renters policy. This coverage is available from most insurance companies. In earthquake prone areas like California, the policy comes with a high deductible.
As far as maintenance damage is concerned, it is your responsibility to take precautions to protect your home from damage. Your insurance policy will not cover damage due to lack of maintenance, mold, termite infestation and infestation from other pests.
