The IRS allows taxpayers to go back a year to claim expenses. You could put all of it on the 2022 return. See Disaster Assistance and Emergency Relief for Individuals and Businesses.
Claiming repairs means normal stuff, generally. See 2022 Instructions for Schedule E (2022) You will want to claim the disaster related loss. See Publication 547 (2022), Casualties, Disasters, and Thefts.
I think the smart bet would be to claim it all together on 2022 as a disaster loss. It is your tax return which means ultimately you decide where you want to put expenses and which year. You could file an amended 2021 to claim the 2022 expenses. If you had a higher income, amending might be better for you.
