I'm from Cape Cod, and all my life I've thought that the plural of roof is rooves. My wife is from the Midwest and thought this was plain wrong, but I did manage to locate some old dictionaries that contain an entry for rooves along with the pronunciation that I use (r-ooh-ves). I'm wondering whether anyone from the Northeast uses the same spelling and pronunciation, or if it is outdated everywhere in the United States. I have also always thought of the plural of hoof as hooves, and I'm pretty certain that I grew up hearing it this way.
You are not going crazy. I remember rooves as well, but the regular plural is winning out.

As for hoof and hooves, most dictionaries still list hooves as the plural with hoofs as an also-ran.
I also like shelf, shelves; elf, elves; self, selves; thief, thieves. But chief, chiefs.
I feel like I'm in a time warp reading mattm say he found some old dictionaries with "rooves" and Glenn saying he remembers it. I never knew it changed. But I must honestly say that it is rare that I either speak or hear the plural of roof. It probably changed and I wasn't listening.
This is 1st time I've ever seen rooves.
There is a continual pull for irregular forms to become regular. Some are well along the way to losing the irregular forms.
