Can I ask the property to stop water supply if the roof leaks upstairs and the water leaks downstairs?

Legal analysis: this can be solved by the property management company, which should be fully responsible for repair, maintenance and help you solve the water leakage problem and make it waterproof. The responsibility of the upstairs owner is inevitable, and it is best to solve the responsibility caused by water leakage upstairs through consultation. If negotiation fails, it can only be settled through litigation. The property company has no responsibility. The reason is that there is only a property service contract relationship between the property management company and the owner. If it involves maintenance responsibility, it only involves the maintenance responsibility of public property and facilities. As for the proprietary part of the owner, unless otherwise agreed with the owner, the property management company will not be responsible. This issue is related to neighboring rights and the protection of property rights in legal provisions.

Legal basis: Article 296 of the General Principles of Civil Law of People's Republic of China (PRC), according to which the owner of real estate uses the adjacent real estate for water use, drainage, passage and pipeline laying. We should try our best to avoid causing damage to neighboring real estate owners.
