How often should the top floor be waterproof? Should the property be responsible? Anjuke

The top floor belongs to the public area, and the property management company is responsible for daily maintenance.

Waterproofing is not something that is done once every few years. If there is no leakage, the water in the top floor room will not be decorated.

Moreover, if the top floor leaks water, the maintenance cost will be shared by all the owners of the building in accordance with relevant regulations. Some owners can say that the top floor has nothing to do with him, but if your external wall leaks, it has nothing to do with other floors, but it is also shared by all owners to repair the seepage of this external wall. That is, apply for "residential special maintenance funds".
