How long is the shelf life of the building roof after water leakage treatment?

The warranty period of roof waterproof layer is 5 years.

For commercial housing, the warranty period of the roof waterproof layer is 5 years, so if the top floor of the purchased building leaks during the waterproof warranty period, it is the responsibility of the developer. Developers are obliged to maintain for free, and must contact the developers as soon as possible, asking them to maintain immediately, so as to prevent the developers from delaying beyond the warranty period and causing maintenance costs.

For commercial housing, if the roof leaks due to man-made damage, even during the warranty period, developers are not obliged to give free maintenance, even if they are willing to pay, developers often will not give maintenance. In this case, we can only find the destroyer to provide maintenance services, or the property provides maintenance, so that the destroyer can bear the maintenance costs. Specific maintenance services and costs can be discussed and decided with the saboteur.
