climbers of any kind generaly dont get the root stock to dammage a house in that way . the thing with climbers is the dammage some of them can do to walls , slates etc .

This one won't hurt your walls - you must have installed some kind of support for it, as it winds itself around trellis or wires - and needs training and tying in, as well!

This vine has a relatively small and soft root system. I wouldn't worry about it pushing over the wall or heaving pavement, though it will grow better if it has some soil area to grow in.
