Hapy,
I'm really glad you asked this question because I had Black Spot on my rose bushes this season and, although I knew Black Spot wasn't fatal, I didn't know what to do about it. You came to the right place to ask your questions, though, ATP is FULL of helpful people!
Do you have a picture of the roses in bloom (even if it's an old and/or blurry picture)? We love pictures here on ATP!
You may even get lucky and get an ID for your bloom if the bloom is distinct enough.
Going back to the black spots...I was surprised when my Firefighter roses, which are supposed to be more resistant to Black Spot started developing what I thought was black spot shortly after I purchased them (just a couple of months ago or less) until Lyn (

Dormancy in roses is triggered by cooler temperatures and shorter daylight hours. If the rose is going dormant, those black spots are just an indicator that the rose is no longer providing nutrients to the foliage and is hoarding all of the nutrients in its root zone.
Thank you, Lyn, for that very informative bit of information! Do you know if Firefighter rose goes dormant, by chance? It's a hybrid tea rose, so probably not what would be considered 'Old Garden Rose'...but is it possible that it goes dormant anyway?
