I would think that one year is too short a time to cause rose replant problems (unless you are a heavy sprayer and have turned your present soil into a lifeless chemical dump). The following link emphasises the importance of having "live" soil.

Here is a link that might be useful: link to âRose Replant Diseaseâ article

Thanks :)

I've replanted roses many times in the same spot where another rose has been and have never had a problem. It's much more of an issue in Europe, for some reason, but almost a non-issue here, especially if you add new bagged soil and new native soil. Your new roses will be fine.
