Within ZIMMERER-Software, the following roof types are considered "complex roofs":
rectangular or odd-angled footprints with an unlimited number of roofplanes, appendices und [Verfallgratung].

Complex roofs are entered by defining a footprint-contour and the desired slope angels (ZIMMERER will then automaticly determine all ridges, hips and valleys) or by combining predefined building blocks, or a combination of both methods.
