Steve and Nancy Chalfant Tornado Damage

My parents neighborhood was hit by the tornado that went through Winchester, IN a couple weeks ago. Many houses in the their housing addition were destroyed and my parents home suffered damage from the storm as well. They found out today that their insurance is not going to cover the destruction and they will have to pay thousands of dollars out of pocket to cover the damages. They are retired and on a fixed income, this amount of money was completely unexpected and they are unsure how to cover the costs. Anything will help.
