Is the roof upstairs leaking or the property?

Legal analysis: the property has the responsibility to assist in checking the cause of water leakage. If there are loopholes in the design of the house, it should be solved by the developer. If it is a quality problem, it should be solved by the construction unit. If the developer and the construction unit can't find it and have paid the property maintenance fund to the property, they can find a property company to solve it. Property companies should be fully responsible for repair and maintenance, help solve the problem of water leakage, and do a good job of waterproofing.

Legal basis: Civil Code of People's Republic of China (PRC).
