Pick off the infected leaves and dispose of them, as well as any fallen leaves!
In a gallon spray bottle add a teaspoon of backing soda (bicarbonate of soda) and a few drops of liquid dish soap and spray the upper and lower sides of the leaves!
If you have mulch around your roses, remove it and dispose of, since the spores will linger there and will be splashed up back on the roses when it rains or when you water! Apply a new layer of mulch.
BTW! Welcome to our forum!

...oops....remember to wash your hands after handling the infected leaves as well as any tools you use!!
That's where I was going too Ron. Also do not top water your roses or water late in the day or at night. Water resting on the plant can cause black spot. Treat them like a nightshade
