A Hogback roof tile is a type of clay roof tile characterized by its unique shape, featuring a curved, saddle-like profile with a rounded top and a flat or slightly concave bottom. The tile's curved shape resembles a hog's back, hence the name "Hogback".

 

This distinctive design allows the tile to lie flat on the roof, but also provides a slight curvature that allows water to run off easily, making it an effective and durable roofing material. Hogback tiles are often used in traditional and historical building styles, and are prized for their rustic, charming appearance.
