According to data from the National Storm Research Laboratory and several material testing agencies, high-quality clay tiles can withstand wind speeds of up to 120 miles per hour (about 193 kilometers per hour) after proper installation. This data is equivalent to the wind force level of a Category 3 hurricane.

It is not uncommon to see black stains on Roman clay tile roofs. These stains are usually formed due to the roof being exposed to the outside environment for a long time and being affected by a variety of natural factors. The main causes include mold, algae, air pollutants, etc.

● Starting at one end of the eaves, place the first tile on the waterproof membrane. ● Use a nail gun or hammer to secure the tiles to the wooden baseboard, fixing each tile at at least two points. ● Make sure the bottom edge of the tile is flush with the eaves, and use a level to check for straightness.

High-quality clay tiles can withstand a static weight of about 150-200 kilograms per square meter when laid reasonably. This load-bearing capacity is mainly used to resist natural loads such as snow accumulation and falling branches.

The water flow intensity of high-pressure water guns is very strong, especially when the water flow is directly aimed at the edges or gaps of tiles, which can easily cause tiles to crack or break. Especially when the wrong water pressure or nozzle angle is used, the surface of the tile may be eroded, weakening its protective layer.
