If you don't like the roses, you cannot plant another rose in the same space without taking some precautions to avoid 'rose repeat disease'. If this will be the case, come next summer, post a thread about it.
I would cut them down by 1/3 now, to reduce wind rock, stabilise them with stakes and then once spring has started weather-wise; late Feb to mid March(?) look at the RHS site, or similar and prune back to about knee height, cutting cleanly at the angle and area that they tell you to. Then feed them exactly as directed on the 'rose food' packet, no more!Good luck, roses are so rewarding for just a little effort.
They are very 'leggy' and whatever kind of rose they are, they could do with rejuvenating after some years of neglect.
