Support Grandma's Urgent Roof Repair

I am raising funds for a good friend, mid-eighties in age, who must re-roof her home or will lose her insurance, and then her bank will re-possess her home and personal belongings and auction them to pay off the mortgage. She lives on a fixed income from social security, and her only living relative is a teen-aged granddaughter. She must re-roof the house before May. Roofers say they must go all the way to the wood to assure it's in good shape. Many thanks for any help you can give.
