If uneven pressure is applied when walking on the roof tiles, especially when the pressure is concentrated in a small area of ​​the tile, the tiles can easily crack. Once the tiles are cracked, rainwater may penetrate into the roof through the damage, causing leaks.

Roman clay tiles and Chinese tiles are both mainly curved, which makes the two visually compatible. In addition, the clay tone of Roman tiles is close to the color of tiles in traditional Chinese buildings, which can be well integrated into the Chinese style.

Different building materials have different thermal expansion coefficients, and clay tiles have a relatively low thermal expansion coefficient. This means that it expands relatively little when heated, especially compared to metal materials or wood. However, despite this, clay tiles still expand and contract slightly under extreme temperature differences.

In 2024, the demand for sustainable and environmentally friendly materials continued to grow worldwide. Terrazzo stone, with its environmentally friendly characteristics, has become an ideal material in line with this trend.

In actual construction, the gap between tiles usually varies according to the type, shape and installation method of tiles, but in general, the gap between clay tiles should be kept between 3 and 5 mm. This gap range can provide sufficient ventilation without affecting the waterproof performance of the roof.
