A lot of the older homes we work on have shed dormers. The purpose of these dormers was more practical in nature in that they added floor area to the second floor of a 1-1/2 story home. Done correctly, they can offer a nice architectural element to the outside of a home as well. Shed dormers are different than gable dormers in that they are much wider and are defined by a single-slope roof. Because they are wider than gable dormers, shed dormers provide more headroom and more space in the upper floor. Shed dormers also tend to go away, whereas gable dormers are often used as more of a focal point.
