    If it vines by wrapping around stuff (and thus needs a trellis like structure to grow on), it should be fine. The other posters are having problems with English Ivy which adheres by digging aerial rootlets into structures (ie masonry, wood) to gain a foothold, and Virginia Creeper which adheres by having aerial rootlets with little pads that produce an adhesive cement like substance. The adhesive has to be continuously renewed by the plant and will eventually fall off the building after being killed. Manually removing Virginia Creeper before the adhesive has worn out will probably damage the siding or wall.

    English Ivy can be quite bad for a building where Virginia creeper is mostly annoying. That depends on the siding of course. Solid masonry or stucco, as long as its well pointed or in good shape is going to be fine. Vinyl, shingle, or anything with an air cavity (masonry vaneers tied to a wood wall) is a real gamble. You dont want little spaces that the vining plant grow up into. That's any kind of vining plant.

    There are some very positive upsides to vining plants if the wall is appropriate and the plant isn't English Ivy. A fully covered wall can considerably cooler on a hot day. Instead of the sun pounding into a solid brick wall, storing all that heat in the wall like a battery, a covered wall will have the plant both reflecting sunlight and cooling themselves down via transpiration. I remember reading a paper where the author compared the temperature of wall covered in ivy vs bare walls and the ivy walls were 15F cooler.
