I am a resident of the top floor, and the roof is being overhauled (repaired) because of rain and snow leakage. Who will bear all the expenses?

Now the property is generally contracted by individuals, but it depends on the actual ability and efficiency of the company. Generally, the problem of floor and wall leakage is solved by property and developers through consultation. If it can't be solved, it's the owner, and there are various expenses. The best way is for the owners' representatives to go door-to-door and ask the property to give a statement. In the Property Management Law, these expenses are borne by the developer, and the property shall not share all kinds of maintenance expenses of public facilities with the owner. In addition, it means that you only bought the usable floor area, not the floor. If you buy the first floor according to this statement, it means that everything upstairs belongs to the first floor owner? In other words, if the owner needs to pay the fee, the owner's representative needs to negotiate with the property to pay the fee uniformly. Who can prove who paid and who didn't? The only thing you can trust now is yourself.
