I have planted "Nahema" in early May (bareroot). The plant is doing well , it is already 6 feet tall.
Plant is healthy, growing and blooming

Last 2 weeks I am noticing that some of the leaves are curling, there is no change in color just curl.
Do not see any holes, spots .

Other rose plants nearby do not have this issue

What kind of treatments should I consider?

The first pic I see a white substance that somewhat resembles powdery mildew on the leaves but the other pics I do not see it???
Powdery mildew on rose leaves will curl the leaves...If it is indeed Powdery mildew I use Greencure...

Have you sprayed those leaves with anything? Thanks...
Is the rose bush well hydrated?

I also have a Nahema rose that is doing the same thing. I live in New Zealand, on the coast, so my rose plant can sometimes be exposed to wind and salt air. The rose bush receives natural rain watering and a good amount of sunshine. We are in Autumn now. Apart from a few aphids which get destroyed by hand the rose bush looks good and healthy. Any suggestions, please?

I see that you have elevated sprinklers by your roses (Image #3).
I've been told to avoid spraying the leaves of a rose bush because
of blackspot. I wonder if that is related to the curling. Just a thought.

The leaves of Nahema curl. That is a distinguishing factor with this rose. I don't know about the others. This doesn't mean you don't have PM, but just that curing it won't necessarily cure the curl. I love roses with odd foliage, so that's one of the reasons why I got Nahema. Some refer to it as holly-like leaves. Mine is young so I'm not sure if it outgrows it.
