I wasn't clear if there are two items for repair or just one. Here, a "Patio" is just an open courtyard, open to the air without a roof; which would not be part of the structure.
Characteristics of a Building that will prevent it from being financed are usually identified by the "Appraiser" who has been educated as to what the requirements are of each loan program. Seldom is an Inspector able to speak authoritatively on these matters.
If it was determined that the entire roof of the house is in need of repair, even though "it does not leak" that is a judgement call and, for me, indicates that the Buyer just wants to nix the Contract. Around here, the Building Inspection is often used a just another means of continuing the negotiations in a manner that can only result in the net price being reduced further.
If you don't have the resources to make any improvements anyway, then I'd just call their bluff, and tell them it is being sold as it is . . . . the way they saw it. If they have decided that they now don't want it, that's their call. You'll just have to wait for another Buyer who doesn't find such fault with these "problems" to make them a "Deal Breaker".
As an aside, when corrective measures have to be taken in a "rush" to complete some changes just to satisfy the requirements of an inspection, a premium price is usually levied, and for the absolute minimum definition of the job.
In this respect, I agree with Super, and even if you have the resources to toss them a bone, I would avoid having the work done myself. Instead, I would offer them a "small" credit payable at closing, for them to use in making the alterations using a Contractor of their own choice.
I don't think that the Lender's Appraiser has even been out to your Property yet.
