A dormer is a small structure built onto the sloped portion of a roof (as opposed to a cupola which is built on the ridge.) Therefore, a dormer will only have walls on three sides, and it's roof will be integrated into the main building roof rather than independent. Dormers can be further described by the type of roof that they have:
Shed Dormer (or Dog Dormer) - the simplest type of dormer has a roof which slopes in the same direction as the main building, but at a shallower angle. Has two triangular side walls and an eave on the facing wall.
Gable Dormer - the most common type of dormer, has a gable on the facing wall and eaves on the side walls. The dormer roofs slope perpendicular to the main roof, so create valleys at the joint.
Hip Dormer - is a dormer with a hip roof. Eaves on all three sides of the dormer and valleys where they meet the main roof.Reminder: Tune in to Twitter today at 1:00pm ET for #GreenbuildChat with +reThinkWood
*Each Wednesday our structural engineer, Rik Vandermeulen, discusses a new term associated with glulam manufacturing. He will do this until we run out of words. If there is a timber or glulam term that you have heard of and want to know more about, let us know in the comments.
