Why Do UPVC Roofing Sheets Fade and Crack?

UPVC roofing sheets, also known as plastic roof tiles, are a popular option for roofing due to their durability and low maintenance. However, over time, these sheets may start to fade and develop cracks, leading to potential issues with water leakage and reduced aesthetic appeal.

There are a few different factors that can contribute to the fading and cracking of UPVC roofing sheets. One common cause is prolonged exposure to UV rays from the sun, which can break down the chemical composition of the plastic and cause it to become brittle. This can lead to the development of fine cracks and a loss of colour intensity. Additionally, extreme temperature fluctuations can also contribute to the deterioration of plastic roof tiles, as the expansion and contraction of the material can weaken its structure over time.

In some cases, improper installation or poor quality materials from UPVC roofing sheet suppliers can also play a role in the premature fading and cracking of the tiles. It’s important to choose a reputable and reliable roof tile manufacturer to ensure that the materials used are of high quality and installed correctly to minimise the risk of these issues occurring.

To prevent or address these issues, homeowners and building owners should consider regular maintenance and inspection of their UPVC roofing sheets, as well as investing in heavy duty corrugated plastic roofing sheets for added durability. With proper care and attention, the lifespan of these plastic roof tiles can be maximised, ensuring that they continue to provide effective protection for years to come.
