Vinyl top install.

I would say no, although it would be nice to remove the trim clips (on my Duster, the original roof was actually screwed down under the clips) which sometimes requires removing the glass to get all of them out (I found, on mine anyways, that some of them couldn't be pulled with the glass in because I couldn't get a screwdriver in well enough to turn them).
I would imagine a lot of replacement roofs don't get screwed down under the clips, and that should be fine too...
