Roof leakage belongs to the housing quality problem, and the developer shall bear the maintenance responsibility during the warranty period. First of all, it is necessary to determine whether the cause of roof leakage is a quality problem in construction or caused by improper decoration or use by the owner. If your roof leakage belongs to the quality problem of commercial housing, the developer should be responsible for free maintenance during the warranty period; If your roof has passed the warranty period, but the roof belongs to * * * facilities, it should be repaired by the property management company with the maintenance fund; If it is identified that the roof leakage is caused by the residents, the maintenance responsibility should be borne by themselves.

"Housing maintenance fund" refers to the maintenance fund for public parts and facilities of residential buildings. The principal is jointly raised by the selling unit and the purchasing unit, and the ownership belongs to the payer. Interest is used for the maintenance and conservation of public parts and facilities of residential buildings. When the interest is insufficient, it shall be shared by the property owner. According to the law, * * * refers to the main load-bearing structural parts of the house (including foundation, internal and external load-bearing walls, columns, beams, floors, roofs, etc.). ), outdoor walls, hallways, stairwells, corridors, etc.

The water leakage in your house belongs to your own scope, not to the public area, so you can't use this public money. Now that the five-year warranty period has passed, I suggest you negotiate with the developer yourself, otherwise you will pay for the maintenance yourself.
