Today, I accidentally saw a customer’s question: what is the reason for the leakage of water when the old house is renovated and installed with resin tile? Today I will show you this secret. If the previous synthetic resin tile roof is not waterproof, it is easy to cause leakage. Just move the leaking part to 2-3cm deep and clean it. You can use asphalt to pour it. Now there are finished asphalt coatings. When the weather is sunny, it will not leak.
There are two cases of leakage at home: one is improper installation of resin tile on the roof, and the other is leakage of waterproof layer. First of all, to find out the leakage of the roof, mainly from the top to the bottom of the roof. First, check whether there are cracks on the roof, whether the original waterproof layer is aging, and whether there are bubbles on the original SBS waterproof roll material on the roof. If there are bubbles, it will prove that the water has entered the bottom of the waterproof layer, so it will leak. There are also drainage ditches on the roof. If there is a waterproof layer, it will be more troublesome. The waterproof layer around the area must be removed and waterproofed again. Pay attention to strengthening the joint with the original waterproof layer. There are many ways to prevent leakage, or find some professional waterproofing companies to solve this problem.
In the previous article, I said that sometimes the roof will drip in winter due to the cold and hot outside. Since someone asked me, I will explain it to you today. Because the indoor temperature is high in winter and the outdoor temperature is low, the resin tile will sometimes drip on the roof. When cold and hot air meets on the synthetic resin tile roof, water droplets will be produced, which is a very common physical “condensation” phenomenon. But synthetic resin tile does not absorb water, so more water droplets will condense and drip.
In fact, the best way to solve the indoor dripping is to make a thermal insulation layer for our house, so that we will not be afraid of indoor dripping in winter. You can also lay a waterproof layer under the synthetic resin tile, or strengthen indoor ventilation.
