How to determine the quality of PVC roof tiles?

PVC roof tiles, as a common roofing material, are widely used in factories, car shelters, vegetable markets, passageways, and other building sites. However, there are numerous types of PVC roof tiles on the market, and their quality varies greatly. To ensure that you choose durable and safe building materials, today’s article will teach you three simple tips to help you select high-quality PVC roof tiles.

1. Observe the smoothness of the tile surface

Good PVC roof tiles have a smooth and shiny surface, without protrusions, spots, black spots, or impurities. The shape should have clear edges and uniform thickness. Poor-quality PVC roof tiles usually have a rough surface and may have irregular flaws, which not only affect the appearance but also may affect the waterproof performance of the roof.

2. Weigh the tile and listen to the sound

Good PVC roof tiles feel relatively light when held in hand. When tapping a PVC roof tile, good ones should produce a dull sound, while poor ones may make a crisp sound. By this method, you can preliminarily judge the density and material of the PVC tile, and choosing a lightweight and sturdy PVC tile helps ensure the stability and durability of the building structure.

3. Smell the odor

Use a fire source to ignite one corner of the PVC roof tile. Good PVC roof tiles will automatically go out after leaving the fire source, while poor PVC tiles may not go out immediately and may emit a pungent smell. This is because some inferior products may add flame-retardants to increase flexibility, but these additives do not meet fire safety requirements and may cause cracking of the product under sunlight.
