Since its clearly wilting because of a loss of roots, you better get out there and cut it way back to about a foot tall or less. Water it several times a week and it should settle in and start to bloom next year. I suspect what you have is 'Dorothy Perkins', one of the most commonly found roses in overgrown or abandoned gardens. It will survive where no other rose would.

Good luck!

Yeah, I was concerned about that as well. My other has way deeper roots, and thicker to boot, than that. I was actualyl afraid we'd pulled it away from it's roots but when I looked, that was it!

Thanks! I knew I needed to cut back the really long one. So, I should cut it down agressively?

Cut it back hard leaving no more than 8 - 12" of cane. The smaller shoots could be cut back to 4 or 5 inches. The idea is to reduce the amount of foliage but 1/2 to 2/3. The plant needs to be able to relieve the stress on the root system while it recovers, and a lot of new foliage requires a LOT of water.

Ok, gotcha! I was thinking the other way around, that it needed foliage to get sun, so I tried to preserve it. I was too cold and possibly rainy tonight, so I will do it tomorrow early morning instead. I watered it right after the pictures and before dark, it was perking up, I think. But I'll trim it tomorrow.

So I shouldn't expect blooms til next year? If it's a climber, would it help if I try to train the canes inward? I don't like the look of trellises, so I am going antiqueing looking for a nice old gate/fence or something for it to have, but it may take a while to find what I want. I guess it won't be priority this year regardless, since it's being so heavily pruned.

Ok, I trimmed it down to about 10 inches this morning. It was looking much more perky anyway, but I did it regardless. Then a huge rain came, I wasn't expecting that. I hope it's ok. I also tried starting sme of the pieces I cut. Is there a trick to that? I've never gotten it to work. My granny tells me I need to stick them down into the ground til it hits a joint and to keep them well-watered and that they should start to root in about a week or so. Is that right?

Those canes might not be old enough to root the old fashioned way. If you have a patch of really sandy soil, the rooting would be better there than in a soil with a higher clay or humus content.

The rains we're going to have next week should be very good for the two you've got started.
You've got enough root for most of the old timey ones to establish; just don't let them get dehydrated when temps go over 70 (Shade with a chair or broken off leafed out tree limbs (One good use for privet hedge).
