I pronounce it that way as well.
Years ago, I lived in both New York and just outside of Baltimore. I was teased ruthlessly for my pronunciation of roof and root, not to mention my use of “pop”. Though, they all did say that I do not have the Minnesoooota accent very much. It was just certain words.
I haven’t turned back. Well, lately, I have relaxed and now say “pop”.;^) However, I refuse—REFUSE—to pronounce Karaoke -Ka-rokey. That just irritates me. I don’t know why. :^D
LOL. It's like changing from harassment to "hairessmant".
