Do We Need To Spend All the Insurance?

We are selling a house. Inspection has been completed and we agreed to replace roof. Estimates have all come in around $12-$15K. We had our insurance co. come out and they agreed to cover but they also included a LOT more such as re-staining our patio, fixing some dents on AC unit, etc. The payout was $24K. Do we need to have everything done they said they would cover when the inspection stated only the roof and both parties agreed? Or do we owe some of that back to the insurance company?
