The black spots you see is a fungus called, believe it or not, "Black Spot" which is common in many roses, including those grown in full sun. There are systemic fungicides you can spray to control its spread, but it will not eradicate already infected leaves. That's why a lot of people suggest spraying your roses every 7-10 days. I frankly don't have the time to do it regularly, but I do spray in the early spring after it rains and when fungal activity is high. Black Spot may disappear once dry weather returns. To reduce the spread of this fungus, do not water overhead - simply water at the bottom radius of the plant.
All roses do better in full sun, but try these for partial shade locations that receive at least 4 hours of sun a day: Angel Face, Delta Queen, Zepherine Droughin, Love and Peace, Eutin, Iceberg, and Ballerina. I have had success with all of these in partial shade, but the blooms are not as prolific as they would be in full sun. You might want to trim overhead branches of tree to let more sunlight filter through the canopy to the ground. Good luck!
