Contact the property first to find out what causes the rain leakage. If it is because of the waterproof quality of the house, if it is within the warranty period of the house, the developer can be required to bear the maintenance responsibility.

Because the roof of the whole building belongs to all owners and all parts, not some owners. Roof leakage can be repaired by using the maintenance fund of the property according to the regulations. If the building is not deposited with the maintenance fund, all owners shall share the maintenance costs.
