Look carefully at the backside and frontside of the leaves to see if there are any kind of tiny pests, and wash them off carefully with water if you find any. Check and wash daily for a while if you do.

However some roses do have puckery leaves, or puckery new leaves, or the leaves may have had some damage when they were emerging before they arrived at your home. If you don't see any pests, have patience and see how they do in the next couple of months.

Remember to protect baby roses from extreme heat.

Good advice from hoovb. Powdery mildew disease and aphids can both cause distorted leaves that persist after the problem is eliminated.

I agree good advice from hoovb to look for reasons why the leaves don't look "normal". My Peace rose in the garden will often have puckered leaves but blooms normally. It is the only one in the garden that does this. Again as hoovb said, it could be the nature of the plant.
A comment about growing roses in the pots: I have done this for the past couple of years. When I receive the "own root" roses from the growers, I pot them from their shipping container into a pot that is at lease twice the size of the shipped pot or larger. They usually come in a one gallon size so I put them into a three to five gallon pot. I fertilze with a liquid fertilizer on a regular interval with a reduce concentration mix at first then change the rate as they grow. I follow the same spraying rotation for insecticides and fungicides as the rest of the roses in my garden. I prune as necessary so new growth is encouraged. I place the newly potted roses in a moderate shaded area at first and transition them into the sun/shade area where they will be growing when planted in the garden. I try to plant these "newbies" into the garden sometime during the mid to late summer so they have a chance to adapt to the ground for wintering.

Identify any "dead end" growth and prune these back gently to encourage new growth.

I was told once that own root roses have very limited blooming in the first year beacuse they are new, but as the get older they bloom more and more each year, and I have found this to be true. Good luck.

Wow thanks for all the great advice. Ill check them and report back.
