Existing archaeological discoveries indicate that the earliest ceramic tiles in the world appeared in Greece circa late 3,000 BC, but only in simple forms. Accelerator Mass Spectrometry (AMS) radiocarbon dating results show that the absolute age of tiles unearthed from the relic site of Qiaocun date back to 2400–2200 BC, proving these as the earliest composite tiles.
In the Western Zhou Dynasty (1046–771 BC), terracotta tile manufacturing was significantly developed in central Shaanxi Province, forming the Longshan Western Zhou culture, which further spread to the rest of Asia including South Korea, Japan, the Russian Far East and Southeast Asia.
To avoid the limitations of previous studies, the research team recruited experts in the fields of archaeology, architecture, relic protection and computer simulation to conduct cross-disciplinary research, overcoming difficulties such as the small sample size and the fragility of the samples.

I’m pretty sure that voids the lifetime warranty.
They fail to show how these titles were fastened in place. I would be interested in knowing that.
I worked in a Chinese village called “Shuifu” in the Yunnan Province in the winter of 1976-1977. The Chinese were building a new natural-gas fed fertilizer plant there. I was in charge of starting the power plant attached to the fertilizer plant.
The village had its very own “tile factory” which was nothing more than a spot by a clay bank, some wire saws to cut the clay, a rubber mold to hand-form the semicircular tile, and a crude wood-fired kiln. Most houses in the village were single-room, made from rammed earth, had open windows (no glass), and had thatched roofs. The “Rich” people had tiled roofs.
I’m sure what I observed was more primitive than the Western Zhou Dynasty (1046–771 BC) terracotta tile manufacturing described in this article.

Don't know how these are done, but since the tiles are heavy, I've seen where they just put a block at the bottom of the row to keep them from sliding down.
I believe wooden pegs into the substructure were used, later nails. Probably some kind of pitch as well. I believe they required maintenance.
“Cuban” tiles were formed over the thigh, then installed using cement. One row was upside-down, the next row right-side up.
Hmm, interesting. There may have been little protrusions on the bottom sides, or perhaps holes and they were stitched in place.
The fastest way to solve national poverty is to redefine it. :^)

I think they fit together like a jigsaw puzzle.............
