I think you'll find that it's powdery mildew. Sorry but I've long since got rid of all my roses as they were plagued with both that and blackspot. I can't remember for the life of me what the cure was - sorry :o(

Here a thing you can try: baking soda in water with a liitle bit of dish detergent. Spray it on the leaves. But I think you have to cut all the sick leaf before.
