I'm just finishing up in the yard and it's mid November. I have both climbers and shrub roses that I've given winter care to. You've given your roses protection by covering the bud union by hilling up but I find by not pruning at this time more beneficial. Don't prune your climbing rose late as unless it really is diseased as it will bud on old wood.
Just support the canes with a tie to a trellis. The same goes for shrub roses too. If the prevailing winds are strong do your best to support them.
I think they need protection that way. Good Luck Rick

Stake and tie them for winter. I never prune in the fall unless something is really long, like 6 or 8 feet, and then I only cut to about 4 feet high anyway. If you want you can put stakes around the bed and staple burlap to them all the way round to make a wind barrier and then if you have them put some leaves down inside to protect the grafts. If most of your roses are hardy you probably don't even need to do that but it may help some of the tender ones. But don't do that until after you've had several hard frosts and the ground is frozen. You want the roses to go dormant and stay dormant. If you winter protect before that they may get too warm and start to grow when you don't want them too. And placing winter protection too early can also encourage critters to build their winter nests in your rose bed. Bunnies will munch on your roses all winter long and in the spring you'll have a lot of cut off stems sticking up. I had that happen to me one year and was really bummed. Here I thought my roses were doing OK only to find when I took off the leaves the canes sticking up weren't attached to the roses any more!
