Roof Constructions circa 1600

In vernacular architecture around the end of the sixteenth century, roof framings were composed of stacked trusses, where the bottom one consists of a superimposed tiebeam, resting on curved rafters with on top a king post or an A-frame. The pitch of the roof held a consistent 58 degrees, based on what was called the "spanroede:". Contemporary carpenters empirically witnessed that this inclination was most effective in keeping rainwater out and resisting the heavy coastal winds. Based on this information and because the width of the floorplan was known, the height of the roof could be derived creating the model. Source: Orsel, E., 2020. De ordinaire kap, Leiden, p.135-137.
