It does. Pick off the affected leaves and put them in the waste bin, not the compost, to reduce the presence of the spores that cause it. It can reduce plant vigours so good hygiene is key.
It thrives in damp conditions but keeping your roses well fed and watering n dry spells will help make them strong enough to fight it. Some of the newer varieties of rose are resistant so you could consider those for any future planting.
In spring, as new growth starts, you can spray the roses with anti-fungal products for roses but most of these also contain insecticide so be careful as to how and when you sue it. You can also make your own anti-fungal spray by steeping horsetail weed in water for a couple of weeks then straining it and diluting it for use.
I have this problem most years on an old rose and just remove the leaves as they become infected. Doesn't seem to affect the flowers. I keep it in a pot and water it daily and feed it weekly, as it is so old, with either tomato fertilizer or seaweed. It has sentimental value so just live with it, although it does look tatty at times.
