Prune away the dead branches and wait and see what foliage buds open. You can nurse them back to health. You will be pruning to shape them once you see which branches are alive and where new branches form. By next fall you will have a good idea of what you are working with.

You will probably want to move them or make roof-like structures to deflect the falling ice.

I had a similar problem myself. With all the snow this past winter, my husband had to get up on our roof and remove some of the snow and ended up throwing the snow and ice right on my Rhodys, so I have about 3 that are looking pretty bad. Two of them are the smaller, thinner rhodys, which appear a lot more fragile. I will wait to see what lives and what doesn't and take it from there.

It's pretty sad when you work so hard to keep your shrubs nice and things like this happen.
