The production of roof tiles during the Roman Empire was a highly developed craft. Romans established factories, often located near significant building projects, to mass-produce these tiles. Artisans developed various techniques to create tiles with different patterns and glazes, allowing for personalization in construction. The color and finish of these tiles could vary, giving homeowners the ability to choose styles that complemented their tastes or the overall design of their estates. This ability to customize was particularly evident in luxurious villas, where different shades of tiles might adorn roofs, enhancing their aesthetic appeal.
