Pitch is the angle at which the roof rises from its lowest to highest point. Most of architects accept in dry regions plan the roof design which has slope or pitch. The pitch depends on weather condition and the material used in the roof. In dry region or in plain area, the pitched/slopping roof is constructed for factory shed.  The 23 degree pitch timber truss looks like a triangle or combination of 2 small triangles having a common middle support.
