What is the height of the ancient sloping roof?

The slope of the commonly used sloping roof generally adopts four points, or five points, or four and a half points, and the roof adopts the gable to the top as far as possible. For example, the roof has a double slope, the depth from front to back is12m, and the bisector is 6m. If the roof is divided into four parts, the building height from roof to roof can be set to 2.4 meters. This is a rough calculation, whether to make sandwiches, whether to be a chef, whether to make shapes, how to make them look good and other factors should also be considered. three
