Is the resurgence of the top floor vents a responsibility?

The property has no responsibility. The damp top floor indicates that the building quality is not good, but the product quality of the real estate agent is not good. Property is just a service company that serves the owners. The roof is wet, and the property can help you coordinate the maintenance staff to repair it for you. The cost has nothing to do with the property, so the wet property on the roof is not responsible. Property was introduced from Hong Kong to coastal areas and inland areas, meaning property, assets, real estate, real estate, industry and so on.
