Black spot is a fungal disease and some rose cultivars are more resistant than others so if you are constantly battling the problem you might consider replacing your roses with more disease resistant varieties. Remove and destroy infected leaves; spray with fungicial soap, sulfur or Neem Oil; repeat at 7-10 day intervals, or after every rain and you should be able to control the problem. Hope so!
