Messung
Neigung = Hoehe / Horizontale × 100 (%). Satteldach Standard: 35-50°. Flachdach: 2-5°. Dachziegel brauchen min. 22°.
Mindestneigung
Tondachziegel: 22°. Metalldach: 3-7°. Flachdach: 2°.
⚡ CalcWolf Insight
Roof pitch affects more than materials — it impacts energy efficiency. Steeper roofs shed snow faster (important in northern climates), create larger attic spaces for insulation, and allow for better ventilation. Flat or low-slope roofs (under 3/12) require special membrane roofing systems instead of shingles.
