When I recommend a rose for zone 3 that means without winter protection. If winter protection is needed, I will expressly say so.
I don't really believe in wrapping plants up to keep them from freezing. Not just because it's a huge hassle but because it ultimately will not work. A rose that is too tender for your zone will weaken and eventually die no matter what you swaddle it in.

But to leave the plant outside and surround it with leaves is not going to do it that much good. Two or 3 degrees of frost protection is all you will get for your efforts.
In places where a thick blanket of mulch will keep the ground from repeatedly freezing and thawing, it makes sense to apply it.
Snow cover will do a better job of protecting your roses than anything you can purchase.
The problem is that not every rose grows well on its own roots. Finding out which ones do and which don't could take a bit of experimentation.
