Why do synthetic resin tile roofs drip water in winter? What are the solutions?

Some consumers have installed synthetic resin tiles at home and sometimes wonder: “Why does the synthetic resin tile roof sometimes drip water in winter due to the temperature difference between hot and cold outside?”

Because the indoor temperature is a bit higher than the outdoor temperature in winter, synthetic resin tiles sometimes drip water from the roof due to this temperature difference. Once cold air flow meets hot air flow on the synthetic resin tile roof, water droplets will be produced. This is a widespread physical phenomenon known as “condensation”.

Another point is that synthetic resin tiles are inherently dense and do not absorb water; therefore, water droplets condense more, leading to dripping.

In fact, there are two best ways to solve the problem of water dripping indoors:

The first type: Add an insulating layer. In this way, even if the outdoor temperature is low, there is no need to worry about water dripping indoors.

The second method: Lay a waterproof layer under the synthetic resin tiles to enhance indoor ventilation.
