Putting down a 3- to 4-inch layer of mulch around your rose bushes can help to get rid of weeds. However, if you can’t reach the weeds by hand, I assume the area is also too difficult to mulch. In this case, you may wish to try one of several postemergent herbicides, like sethoxydim, fluazifop-P-butyl, or clethodim. These chemicals are generally safe for roses, but before you use one, be sure to read and follow instructions on the label!
