Hail damage insurance claim - what do I do with the $$?

[Larry Flanagan]

I am selling a house, it is pending for the second time.  The first buyer had the roof inspected and reported hail damage which I turned into my insurance.  Insurance co confirmed damage and wrote me a check to replace roof cover - which I have not yet done.  Subsequently, that sale fell apart for another reason.  House went back on market and is now pending again.  New buyer performed inspections and did not report any issues with roof.  I am sitting on this large check for a new roof, what is my responsibility to this buyer & my insurance company?
