Why do synthetic resin shingles make squeaking sounds? What should we do?

Synthetic resin shingles are increasingly being used in building roofs due to their lightweight, durability, and aesthetic appeal. However, during installation and usage, many users will notice that the roof sometimes makes strange noises. This phenomenon is actually caused by the thermal expansion and contraction characteristics of synthetic resin shingles and is a normal situation.

The thermal expansion and contraction of objects is a natural principle, and this phenomenon exists in most building materials, including synthetic resin shingles. When the temperature changes sharply, the volume of synthetic resin shingles expands or contracts, causing friction or misalignment between the shingles and the fixed structure, which results in unusual noises.

During installation, if the fixation is too tight or too loose, it will affect the free expansion and contraction of synthetic resin shingles. Tight fixation will hinder the expansion of the shingles, while loose fixation may cause loosening during contraction. Moreover, in areas with large temperature differences between day and night, synthetic resin shingles undergo multiple thermal expansions and contractions within a day, making them more prone to strange noises.

To reduce and alleviate abnormal noises, a reasonable installation method can be adopted, leaving some expansion space and using screws with rubber gaskets. Before installation, place the synthetic resin tiles outdoors for a period to allow them to acclimate to the ambient temperature. In addition, regular inspection and maintenance of the fixation status, as well as cleaning the debris on the tile surface, can also help reduce abnormal noises.
