Looks like this? (Blackspot) If so, the article details what to do.

On the long shoots, cut your blooms as they open (take them inside and enjoy them ). You make a cut at an angle using very sharp pruners, 1/2" up from the first full set of 5 leaves IF that set points outward. If it is pointing inward, go down to the next one. This helps direct the next growth to open outward for better air circulation and form. Since you're already having trouble with disease, be sure to carry a spray bottle with diluted bleach water to sanitize your pruners as you move from bush to bush. Wipe them dry with a rag.

Hope that helps!

Yellow leaves could be a number of different issues. It could be from disease, insect infestation, or a nutrient deficiency. Check the back of the leaves, if there is powdery stuff in blotches it's rust, it can be orange, red or black. Rust is a fungus, remove all the leaves that have those spots and dispose of them in the trash.
If the leaves are yellow in splotches with some green still visible it could be a virus, which is throughout the rose and can't be cured. But it rarely spreads to other roses. It causes stunting and poor performance in the affected plant.
Fertilizing will help no matter what the diagnosis, and for any fungal problems (very common in the spring with all the rain ) garden sanitation will go a long way to keep them from spreading. Clean up any leaves off the ground and spread new mulch every year. Most fungi can overwinter on the ground and rain and overhead watering will splash the spores back up on the plant. As Journey said sterilizing your clippers will keep disease from spreading between plants. I prefer to spray my clippers with rubbing alcohol, as bleach is corrosive to metal. Roses are pretty resilient, so don't be afraid to remove infected leaves. I nearly defoliated my roses one year when I had a bad fungus problem, and they bounced right back, as pretty as ever.
Good luck with them!
