Looks like sunburn to me. Too much sun and heat reflecting off the walls there most likely.

The roses look like they've been there awhile. Check to make sure they are still getting watered.

Morning and night? Maybe you are overwatering.

Odaharry, why did you repeat your post saying "Morning m night"? Is the "m" a typo or does it actually mean something?

It's been very hot there and your sun is very strong. You could try to shade them a little during the hottest part of the day and wait for it to cool down.

In my hot, dry climate that is a sign that the roses are not getting enough deep water to hydrate the foliage.

Deep watering provides long-term moisture to a plant. The anchor roots pump up moisture to the top growth. The soil moisture down deep doesn't evaporate as quickly as the surface soil moisture.

Your daily watering may not be enough to water the whole root mass, so it is inefficient in getting moisture up to the top growth.

Most rose literature defines deep watering to have moist soil down to about 18". Of course plants don't measure how deep you have watered, but you can see water stress by burnt foliage.
I'd rather weed than dust ... the weeds stay gone longer.
