An overhang is a rock wall or an artificial climbing wall with a slope of more than 90 °, which is steeper than vertical . In the case of particularly strong overhangs that almost or completely reach the horizontal , one speaks of a roof .

When climbing , overhangs and especially roofs pose particular challenges to both the technique and the constitution of the athlete. With increasing steepness, the strain on the arm and hand muscles increases, as a smaller proportion of the body weight can be carried by the feet, resting points for relaxing the muscles, especially no-hands rest, are rarely found in overhangs. Climbing techniques for overcoming overhangs include, for example, shifting the body's center of gravity as close as possible to the rock and building up the highest possible body tension . Some climbing techniques, such as the foothook, are used almost exclusively in overhangs and roofs. For a long time, roofs in alpine climbing were almost exclusively conquered using technical climbing . In modern sport climbing, on the other hand, heavily overhanging terrain is no longer a specialty, climbing halls often consist largely of overhangs and roofs.

A well-known example of heavily overhanging terrain in nature is the roof in the north wall of the western pinnacle , the upper end of which is about 40 meters horizontal from the base of the wall. Difficult climbing routes , which are characterized by overhang and roof climbing , are Separate Reality and La Rambla .
