A roof-boarding hip end (Dutch “haaieind”) is the end of the planed tongue-and-groove roof boards that is fixed to the hip rafters, or to any filler pieces. It is a trade term from roof construction.
Characteristics
The hip end occurs on sloping roof planes that meet a hip rafter at an angle, such as on a hipped roof or a half-hipped (jerkinhead) roof. Because the roof plane runs diagonally toward the hip rafter, the tongue-and-groove boards must be cut tapered, that is at an angle, at that point. The angled end of those boards is then fixed to the hip rafter. Where a single board comes out too narrow, it can be fixed to a filler piece instead of directly to the rafter.
Applications
The term matters when laying roof boarding on roofs that have hip rafters. The carpenter cuts the boards at an angle so they meet the hip rafter neatly and form a closed roof plane. A carefully executed hip end gives a tight join along the hip rafter and a sound base for the roof covering that follows.
