It looks like winter die back. This winter was brutal for roses. Just cut out anything that looks brown, black or looks dead. The roses should grow back fine.

I agree with Buford.

That still has parts alive....so is worth a removal of winter dead parts to let the live parts fill in the voids.

Thanks so much for your answers everyone. I kind of thought that but was thrown off by all those thorn clusters. Thanks again.
