Imbrex and tegula

Overlapping roof tiles used in ancient Greek and Roman architecture

The imbrex and tegula were overlapping roof tiles used in ancient Greek and Roman architecture as a waterproof and durable roof covering. They were made predominantly of fired clay, but also sometimes of marble, bronze or gilt.
