Palmer Huricane Harvey

We had 8" of water in the house and now the roof is leaking. So many of you have offered help and I'm eternally grateful. I don't know what we're doing at this point or where we're going but we're trying to fix the house. When we bought it 15 months ago they told us it was impossible to flood, so the recommended not wasting money of flood insurance. Now I don't know how to recover.
