Throat (roof)
The throat (also the throat , as well as Ichse , e.g. in Vienna) describes a line (edge) on the roof where two roof surfaces meet where there is an inside corner of the building, i.e. H. the corner has an angle of more than 180 ° on the inside.
The ridge , on the other hand, results from an outside corner, i.e. H. the corner has an angle of less than 180 ° on the inside of the building.
The roof surfaces, measured on the inside, also have a raised angle to each other of more than 180 °. But it is smaller than the angle of the walls in the plan.
In the case of wooden roof structures, a valley rafter can be located on the valley line. With traditional roofing with tiles , the roofer always covers the gutters and eaves first, while ridges and ridges are last.
