One of the most common types is the gable dormer, which features a triangular roof that mirrors the main roof's pitch. It's often used to create additional headroom in attic conversions.

Gable Dormer

Gable dormers are easily recognizable by their triangular roof shape, which matches the main roof's pitch. They typically span the entire width of the house, providing ample space and light.
