In my zone, broadleaf evergreens (and ivy would qualify as such really) took a real hit this past winter; many brown and burnt-looking leaves. Exposure to winter winds (especially if first warmed up by the sun) made the leaves dry out and get crispy.
I woud look to see what’s going on; the plant will tell you where it plans to break and create new growth (how far down the stems). You may find it regenerates, sprouting new foliage all along the vines, or that instead it was so badly hit it needs to cutback. Let the plant tell you how far the damage extends before you act.
