The Science Behind Noisy Plastic Roof Tiles

Plastic roof tiles have become a popular choice for many homeowners due to their lightweight, cost-effective, and durable nature. However, there is one complaint that is often associated with these tiles – the annoying squeaking and creaking noises they produce. Many people wonder why these plastic roof tiles make such sounds, especially during hot weather.

The main reason for this noisy phenomenon is the expansion and contraction of the plastic material in response to temperature changes. When exposed to direct sunlight and heat, the plastic roof tiles expand, and as they cool down, they contract. This constant movement can cause the tiles to rub against each other or against the roof’s structure, resulting in the undesired noises.

To address this issue, there are a few solutions that homeowners can consider. Fitting roof tile vents can help to regulate the temperature and reduce the expansion and contraction of the tiles. Additionally, installing heat insulation roof sheets underneath the tiles can provide a buffer against extreme temperature changes, thereby minimising the movement of the plastic material.

Another effective solution is to opt for a PVC roofing system that is specifically designed to reduce noise from thermal expansion. PVC tiles are engineered with materials that offer better flexibility and resistance to temperature changes, ultimately minimising the occurrence of squeaking and creaking.

In conclusion, while plastic roof tiles can be an attractive and practical choice for roofing, the noise they produce can be a downside. However, by understanding the science behind this issue and implementing the appropriate solutions, homeowners can enjoy the benefits of plastic roof tiles without the annoying noises.
