To allow for better air circulation in the unit. Due to the heat generated on the roof. I think.
isnt the roof designed and isulated against heat and water seepage?

I don't really know for sure, it's just a logical guess. Roof insulation may be there. But the top floor units are subjected to the direct heat of the sun. Ambient air temperature will be higher as compared to lower floors. Water proofing may be there too, but leaks can still happen.
They finished building your flat and realized got extra leftover cement so they made the roof higher
if the roof leak, the water will take longer to travel to the floor
how does cooling work on higher ceiling?
hot air rise, cool air sink?
warmer air rise to the ceiling and still trap inside the unit for sure.
anybody can explain the science behind this risng and sinking.
i saw my friend unit and ask one of the main contractor worker.they also do not know the logic behind.
understand that hawker center have very high ceiling.but they do also have opening on the extreme top to vent off the warmer air.
it is an elevation treatment in term of design lah, if all looks equal then no punch, must make top most higher a bit as a fullstop la, this is not only HDB, any building takes on this principle
