Answer
I am sure it is mildew. Some roses are more susceptible than others. As a preventative, you can apply Rose Defense or Cloud Cover once a week starting when the new shoots are 3" long. There is also the Bayer All in One for Roses that prevents disease, feeds, and kills insects. Once the mildew is here, you can treat with a Copper Spray. It has also been recently discovered that a spray solution of 9 parts water and 1 part milk will cure mildew. If, as you say, nothing seems to help, the rose you own just is not suited to your climate. It may seem cruel, but replacing it with another variety may be the best answer.
