Roofs is generally used, but is rooves archaic or just wrong?
COCA BNC roofs 2307 653 rooves 1 5
The Corpus of Historical American English has 6 cites for rooves, one from 1890, two from 1930, two from 1950, and one from 1980.
Merriam-Webster doesn't even mention rooves at all. The Collins English Dictionary mentions the pronunciation /ruːvz/, but not the spelling rooves. Finally, Wiktionary has these usage notes:
The plural rooves is uncommon and is usually considered incorrect.
So if you want to be on the safe side, I would recommend going with roofs, especially if your audience is American.
