Wow looks like some insect went crazy with painting graffiti on those leaves... :-O I've never seen anything like that so have no idea...Hopefully someone can help...

Leafminers!

I considered leafminers, but when I looked at the images they were on the top of the leaves and their lines were long paths. :/

Just when I thought I had seen every thing, Those are very unusual. I know there are people that you can send images too for an id but I'm drawing a blank on names. Hope someone else chimes in. Do you by chance have an artistically talented little one at home. One that also has a sense of humor. The leaves are just too healthy.

I'm off to look this up but I'll most likely not find anything.

Is this a southern garden problem.? Never seen this up north here.

Lol that would be hilarious, but I can't see any kid taking the time to go to every single leaf on my roses to draw that. I'm just afraid it might become something serious and it'll spread to all my other plants. Not sure if it's a South problem, but I had went to my Home Depot here to inspect their roses to see if they had problems too, but they were all just perfectly pretty green on the underside >.<.

Mmmm I would guess leaf Miners too..... those lines look like snack trails, plus on the top leaf I see a darker spot on the upper right hand side is possibly a larger leaf miner. Can you take some more pics in a day or two Flying Potatoes? I'm curious, I wanna know if the patterns become more noticeable?

Honestly I would take them back rather then take chance on starting another rose problem that your garden does not need. Do they spend any of their lifecycle in the soil? Has the problem been brought to the attention of the manager. I believe the plants should be disposed of.

I got them as bare roots from Aldi during their Special Buy sale and got soil from Walmart. They're all about two months old. There's no "winter" in South Florida LOL. Btw thanks for the responses. Since majority thinks it's leafminers then I'll spray for them. It's just that I find that odd when I have so many other yummy vegetable plants growing around the roses, yet those leaves are untouched.

There are insects that are so species specific it is astounding.

Take the dog flea. It can bite you to get a meal, so it thinks, but it cannot live off your blood because human body temperature is too low for female fleas to effectively reproduce.

Bird lice cannot infest humans.

So, a leaf miner fly preferring roses is very likely a reality.

Many leaf miners are forever once you have them. You could throw the rose or roses away. Bag them and the soil and place in garbage. It is not easy to kill an elusive tiny fly and eventually will spread to the rest of your roses.

A spray likely won't work because they are on the inside of the leaf. You will probably need to use a systemic.

Bayer's 2 in 1 would kill it.
