@solarsacco No, I was referring specifically to the Solar Credit.
What does your CPA base his thoughts on? Nothing that you posted indicates a roof would be included. For MOST credits and deductions, there are limitations if an improvement "constitutes a structural component". What you posted just says that limit does not pertain to the solar credit. That does NOT say that everything done at the same time would be included in the credit.
There is nothing that indicates replacing your regular shingles would be included in the credit.
