A dormer is a roofed structure that extends beyond the roof and includes a window. It’s a typical feature in a variety of home styles, from Cape Cods and craftsman bungalows to Tudors and colonials. A dormer is also a common addition for renovation projects, particularly when the goal is to create more usable space in a half-story or attic. And in a new construction home, a dormer can be a way to acknowledge the home is a contemporary interpretation of a particular architectural style or simply a way of adding character. In short, a dormer is a small design detail that can have a big impact.

Dormers are named according to the shape of their roofs, so a gabled dormer has a triangular roof with two sides that meet at a peak. We’ll explain a bit more about the most popular dormer styles in this section, plus give some ideas about selecting the right windows for each style.

Gabled roof dormers are classic on Cape Cods where double-hung windows are typical. Of course, lots of different home styles include gabled dormers, and lots of different types of windows can work here. So, consider starting with this question: Am I going for a symmetrical or asymmetrical façade?
While symmetry is certainly characteristic of a Cape Cod, asymmetry is characteristic of a Tudor — another home style that typically features gabled dormers. If your home’s exterior style is more symmetrical, consider matching your dormer window to your first-floor windows. If it’s asymmetrical, you could go for a statement window in the dormer and maybe even choose an interesting shape.
