Man, theres always trouble makers! I only ever had one that had that bad habit and she always seemed to choose the stormy nights to do it. If you get a push broom you can get them down and carry them to the barn on the bristle end of the broom.
If it were me, I would watch them and sell the offender on craigslist. Usually the SSH is supposedly a flighty bird but look for which one flies up first. so the options are, you sell the one you observe flying up there first, or you let them stay up there and if a raccoon or possum finds them, they are eaten or you sell both of them. Or you sit under the tree on a garden chair at sundown with a broom and scare them away from that tree by smacking the low branches with the broom and tell them "go to bed!" and you can herd them towards the coop with the broom held out to the side like an extension of your outstretched arm.
