What are the precautions to pay when choosing roof tiles?

Many people choose roof tiles because of their beautiful appearance and durability, but there are also many manufacturers of roof tiles in the market. Therefore, when choosing, it is important to pay attention to many issues. Below is a summary of the following points, hoping to be helpful to everyone.
1. Weathering resistance of roof tiles
Tiles are located outdoors and can withstand long-term exposure to sunlight and rain. Therefore, it is important to pay attention to weather resistance, waterproof, corrosion-resistant, and high-strength. In addition, friends from the north also need to consider frost resistance when choosing. The tile surface may peel and fracture due to low temperature, so try to choose roof tiles with higher density.
2. The shape of roof tiles
Nowadays, roof tiles also come in many shapes, with common ones being not only wavy, but also flat and square scales. The roof effect created by different shapes will also vary, for example, the staggered corrugated roof tiles will present a sense of undulation and better aesthetics.
3. Dimensions of roof tiles
Generally, the size error of a single tile should be controlled within 2mm. If the size error of the roof tiles is large, large gaps and even warping may occur after paving. So when purchasing, the size of the roof tiles must be well controlled to ensure that there are no gaps in the overlap during construction.
4. Color of roof tiles
It is best to choose a color with uniform and soft matte tones, and the roof tiles in the same area must ensure color consistency. There should be no spots or tiles with different shades of color, otherwise it will reduce the overall aesthetics.
