Before delving into the transformations, let's briefly understand what dormers are. Dormers are roof structures that project vertically from a sloping roof, typically containing windows and sometimes used as additional living space. They can significantly alter the appearance of a home, making it crucial to choose the right style and design.

Gable dormers have a triangular shape, similar to a gable roof. They are often used to add height and interest to a home's roof line. In the before picture, the home has a simple, flat roof, lacking any architectural detail. After adding a gable dormer, the home's silhouette is more dynamic, with the dormer's triangular shape creating a focal point.

Shed dormers have a flat roof that slopes down from the main roof. They are a more subtle addition but can still significantly improve a home's appearance. In the before picture, the home has a monotonous roofline. After adding a shed dormer, the roof line is broken up, creating visual interest and adding character to the home.

Blending Architectural Styles with Dormers

In this before and after example, the homeowners wanted to blend their home's Craftsman style with some modern elements. By adding a shed dormer with large windows, they were able to create a striking contrast with the home's original gable roof, while still maintaining the Craftsman style's charm.
