I know that most varigation in roses is due to a virus. I'd love to have one red and white striped shrub rose that keeps its varigation year after year. But they have all come back plain red. I now have several red only roses that I rather not have. Is this a common fault for all is it just my climate?

I don't actually know, but I'd guess the climate was the problem if you live where it gets cold enough in the winter to kill back branches.
I had a row of beautiful yellow roses that were grafted onto a different root stock. One year they froze down to the ground and when they came back in the spring they were all red.

Very temperate here. I just wonder if most striped roses do this.

Are you sure what you are getting isn't actually the rootstock?
If the right conditions are present, the rootstock part will begin to grow out canes, and if on what is called Dr. Huey rootstock, the flowers will be red, and look like wild roses.
These rootstocks are very very robust and will kill the grafted plant very quickly.
To know, you follow a cane down to the ground, and dig away soil if necessary, and see if that cane (or canes) is/are growing out of the rootstock part. If so, dig the whole thing up and pitch it. Lesson learned.
Then on future roses, you must know how deep to plant the grafted bud part. In super cold climates you must cover it to prevent winter death. In warmer climates, you have it just above soil level.
When under the earth, the rootstocks will tend to grow more canes.
You can cut them away, doing so right away, and cut at where it comes out of the root.
They look different from the other parts of the upper grafted rose too if you look really carefully. The leaves will be different, smaller often, and they will shoot out long long canes very quickly (your first clue!).

No, it is clearly the scion coming from well above the graft. The roses have the same large size and cabbage form as the varigated blooms the year before. The white simply disappears.

Surprise- I deadheaded the first flush of bloom and the next flush have come out varigated. I put it in as my new avatar.

What a beautiful rose. Reminds me of peppermint candy!
