Looks like blackspot on the leaves. The flower buds appear to have some insects on them as well, possibly aphids but they were hard to see, and the dead branch at the bottom of the picture shows webbing seen with spider mites.

Roses tend to be high maintenance. Aphids tend to love roses...in a litre spray bottle put a few drops of olive oil....and a few drops of liquid dish soap....fill with warm water and shake well....use on aphids and other small insect pests on new growth and flower buds.
For the fungal condition: remove all infected leaves and bag them up (do not compost them) clean up any fallen leaves off the ground....use a fungicide on the whole plant and also the soil surface around the plant. Use a layer of mulch (preferably shredded cedar bark) to cover the soil surface to prevent rain from splashing the fungal spores up onto the plant.
