Aphids (greenfly) often carry viruses which will weaken the plant. They suck the sap of the plant to live, and can produce live young asexually,(without a male) at a rate of knots.
If the roses are outside, you could try hanging a fat ball over the plant on a string. The blue tits will come for the fat ball,and while they are waiting their turn, they will eat your greenfly as well.
Fidget, what a fab idea, thank you I would never have thought of that.....another note for my notebook
I use washing up liquid in water and spray it on, quite a strong solution. I can't remember where I learnt that from but done it for years now and it works. Will definitely be trying the fat ball now though

what do you mean at the rate of knots
Very quick. Aphids breed faster than rabbits.

If you see ladybugs on your roses then just leave them as they eat aphids.
