I agree too. March is the classical month for rose pruning, but your rose is already fairly severely pruned so leave it. Is it a climber? You say you trailed it up a fence. If so then let it keep some long strong stems as a frame and when you prune just cut off weak shoots, very old and woody shoots and the side shoots growing from the main stems to two or 3 buds.
Make sure it doesn't dry out in summer, and feed it, I use rose fertiliser as it has the right minerals. Instructions are on the packet. Feed as growth starts in spring and again after flowering is the basic minimum. Roses are quite thirsty hungry plants. They also like being mulched with well rotted manure. A well fed rose is better able to fight disease.
Roses often get a bit tatty later in the season. Don't spray against insects, you will kill good insects too, but do spray with a fungicide against diseases like black spot, mildew and rust.
