I'm not sure when that plural form went away, but, if I have to read about buildings collapsing...

...under the weight of heavy snow and ice, then I want my "rooves" back!

"Roofs" just doesn't do it for me, and I have no interest in moving to New Zealand or Australia, where I have read they still use "the older form of the word."

(Even the bloody blogspot.com spellcheck doesn't recognize "rooves."  But then again, it doesn't recognize "blogspot" either, so perhaps that's not the best bellwether ever.)
