According to the basic rules of condominium ownership, the roof space of a building should be owned by all condominium owners. Therefore, the maintenance of public parts such as roof leakage is shared by the residents of the whole building. If the water leakage is caused by abnormal use reasons such as improper decoration or use by residents, then the residents can be required to maintain and compensate for the losses; After the warranty period, leakage caused by non-man-made damage shall be borne by the owners of the whole building. If the community has collected the maintenance fund, it will be paid from the fund.

Reminder: According to China's property law, "the owner has the right to possess, use, benefit and dispose of the exclusive part of his building. The owner's exercise of rights shall not endanger the safety of the building or damage the legitimate rights and interests of other owners. The owner shall enjoy the rights and undertake the obligations for the part other than the exclusive part of the building; Do not give up rights and fail to fulfill obligations. "

So the roof is a public part. Can you build a house? Think about it.
