Frank, if you have the space and if they are bare root, just heel them in and they will be fine.
This method of handling roses when it is too cold to plant them out has been used forever. I first read about it in Jack Harkness's book, Roses.
It's much better than biting the bullet and planting them out.
Or you could pot them up and store them in your garage or basement. However, that has you messin' with the roots again when you go to plant them out.
