There is no problem with planting bare-root roses as such - I have grown most of mine that way, as it's the cheapest easiest way to get a wide choice of roses by mail-order - but only as long as they are healthy, properly labelled grafted cultivars, recently dug, well-wrapped, never allowed to dry out and planted into suitable soil straight away (and where I live it's really too late in the year to be planting bare-root, though maybe not where you are). Cheap plants from bargain stores may not tick all these boxes.
If they're dormant plants, the soil temperature doesn't matter as long as it's not frozen or flooded. Good rich well-drained fertile soil, for preference - if you don't have that, add compost and slow-release fertiliser. Most cultivars do best with at least partial sun.
