Expert Response
Can you explain a little more about why you will be raising the entire soil level? Will you also be raising the soil around other existing plants (besides the roses), like trees?
Adding 12" of soil would not be recommended...and even adding that much mulch/bark could be detrimental.
If you plan to ago ahead with adding soil, you could dig out the roses, going out as far as possible with the largest root system, and then replant once the new grade has been established.
