Our did too and looked healthier this year than ever...then the deer started chewing them to pieces and before we could protect them, the remaining leaves all turned a weird tan color. Not brown, not spots, but just tan leaves...the veins stayed green but the rest of the leaf is tan.
Haven't been able to find out what that means yet but it looks like they are dying altogether. Earlier in the season they had a good side dressing of compost, some epsom salts and they had been sprayed much earlier in the spring with a copper fungicide, which seemed to benefit ALL the roses, producing the deepest green leaves and healthy new growth.
Now it looks like they will die.
