Although I haven't read the entire site, Organic Rose Care (sponsored by the American Rose Society) may be able to give you good general advice on keeping your roses healthy, no matter what climate zone you're in:

Preparing roses for winter will be different depending on where you live. My "preparation" for winter is just to stop deadheading them and stop fertilizing them right about now. When they go dormant (lose all their leaves), I rake up everything and wait for a frost. If no frost is forthcoming by mid-January, I need to prune them right then, before growth buds appear, and give them sulfur and horticultural oil spray to help prevent black spot, rust, powdery mildew, etc.

But I live in the San Francisco Bay Area. If you live where it snows or you have heavy freezes, winter rose prep. will be quite different.
