Barrel tiles, also known as mission tiles or Spanish tiles, are a type of roofing tile that have a distinctive curved shape, resembling a half-cylinder or a barrel cut in half lengthwise. They are commonly used in Mediterranean, Spanish, and Southwestern-style architecture and offer both functional and aesthetic benefits. Here’s an in-depth look at barrel tiles:
 
Characteristics of Barrel Tiles
 
Shape and Design: Barrel tiles have a semi-cylindrical shape, which allows them to interlock when installed on a roof. They come in two main types: convex (cap) tiles and concave (pan) tiles. The cap tiles are laid in an alternating pattern over the pan tiles to create a watertight seal.
Material: Traditionally, barrel tiles are made from clay, but they can also be made from concrete or other composite materials. Clay barrel tiles are often preferred for their natural appearance and durability.
Color: While natural clay barrel tiles have a characteristic terracotta color, they are available in a wide range of colors and finishes, including glazed and unglazed options.
Size: Barrel tiles come in various sizes to accommodate different architectural styles and roofing needs.
