My bathroom roof is leaking

Hehe, as long as there is a leak on the ceiling of your bathroom, you can only find upstairs! It has nothing to do with the property! Because the bathroom developer has done waterproofing, but also done a closed water experiment, you have to accept before you can decorate, you will be connected to the water pipe when you decorate, the first developer did the waterproofing destroyed, so you still have to do the second waterproof, more responsible property will also be called downstairs to see.

You look at whether the water seepage point is long-term water seepage or water seepage after using the toilet or after the floor drain, long-term water seepage is the water supply pipe leakage, not long-term water seepage, that is, the floor drain of the sewer or the toilet is not installed well, in this case you can find the upstairs residents to solve, the responsibility is not you, it is estimated that the waterproof layer of the bathroom of the upstairs residents was not done at that time.

If there is a water pipe buried in the floor slab, there will be this suspicion, even if there is a water pipe, there is a warranty problem, indoor water pipe, the developer gives a warranty period: 3-5 years. For repairs outside the warranty period, you have to pay for them (in this case, it should be the owner of the upper floor).

You can check and contact your upstairs resident if it's a water leak. If it is a problem with the quality of the project, you need to contact the property and the developer to coordinate and deal with it.

If the upstairs waterproofing leaks at all, it may be that the pipes in the floor slab have been planed and leaked, and this is not a public part of the pipeline property, and it should be the owner of the upstairs who is responsible for repairing it.
