Not a lot of experience with catlin elms, but with the others I've worked with you'd just chop the root back in spring hard and it'll sprout new roots at the cut end.
If that is the entire root system "leader" for your tree, then you have no choice but to address it some way. If there are other roots coming off the trunk, then it's just one of many and even if it doesn't regrow you'll only be out an ugly root. Win win.The catlins don't have the vigor of the parvifolias so that concerns me.

There's nothing urgent in this root removal. Wait till spring, take the tree from its pot and you can examine it thoroughly and make a decision. Deciduous species respond very well to hard-pruning in spring.I.....think.... there are more roots. One more for sure on the other side of the trunk. Fairly big. I think.
Can't get in to see good with it planted.
The fucking heat is even attacking my Scots pine. And I keep it where shade hits it by 2PM.
Shit!
And I even mist it pretty good when it gets hot.
I just now moved it even farther from the afternoon. Goddam rack should be moved to the river!!!
I probably misstated "misting." It's actually pretty much overhead watering to cool the tree ..and..water it. In the mornings I water the soil at soil level.If a pine is having trouble with heat I think you are not watering properly. I have problems when trees are root bound because it is difficult for the water to penetrate into the root zone and there may be very little space left to hold water. In such situations where repot is not an option I soak the pots each week to make sure the whole thing is actually wet. Misting is very temporary. Proper watering is paramount.
