The insurance payment is not a qualified disaster payment.
I would handle it this way and this is just me (I have done this before, however).
Roof is damaged to the extent that it needs to be replaced at a cost of $100,000. Insurance covers the entire cost except for the deductible. I would (and have) decreased the basis by the amount of the insurance payout and increased the basis by the cost to replace (for a net change of $0) and then written off the deductible as an expense.
