What is important to know

  • A dormer consists of a front wall with glazing, side cheeks and its own roof: either gable, with its ridge across the main one, or single-slope, rising gently upward. The dormer roof meets the slope along valleys.
  • The roof plan shows the front line, the cheeks, the dormer ridge and the valleys.
  • Dormers are placed on the slopes of the main part; on a hip roof only on the long slopes, not on the hip ends. A dormer that is too wide near an end is shifted inward.
  • The slope under the dormer is not cut out: the dormer is not yet visible from inside the attic.
