Answer: Bare root roses are usually planted very early in the spring so they can come out of dormancy naturally as the season warms up. Container roses are also usually planted as soon as they are available for the same reason. If the roses were held in artificially warm conditions such as in a greenhouse, they may be quite tender. You could plant them now, but be careful to cover them if a very cold night with frost threatens. Ordinarily they would be fine without such protection, but if they have a lot of tender new growth it would be a wise thing to do.
