What are the causes of water leakage on the top floor?

1, the roof of the house leaks easily after a long time. This is because the previous waterproof protection has lost its function because of the long time of the house, so the rain will leak out from the cracks in the wall. Especially the leakage of old houses will become more and more serious. If left untreated, it will rain heavily outside and light rain inside.

2. Some residents will set up vegetable gardens and flower stands on the top floor, but when designing these, they didn't do a good job of waterproof isolation, so water poured in through the floor will make the lower floor leak, and some even got a pool on the roof. If this is not waterproof, the erosion of the subfloor will be very serious.

3. If the roof of the new house leaks, it may be the quality problem of the project, because the building materials are cut corners, or the waterproof project may not meet the standard. In this case, there must be other quality problems besides water leakage, which will be more troublesome to solve.
