If your HDB flat is still under the Defect Liability Period, you don’t have to worry because HDB will pay for any ceiling leaks or water seepage repairs. In fact, HDB offers warranties on ceiling leaks and water seepage of three years and five years, respectively, covering you for three and five years after purchase. However, if water seepage occurs through the roof or walls of your HDB flat after it is no longer under warranty, you may file a complaint with your town council.
