Hi everyone,

Am currently doing reno to my unit which is at the highest floor. Wife and I really like the high ceiling, however, the roof is just above us.

We know this as the contractors opened up the false ceiling and revealed that the roof of the building is right above. We also realised that the metal roof does not have any insulation. It is just a bare metal roofing.

There is a gap of air between the metal roof and our home's false ceiling.

Just want to ask those with this experience whether there is a need for us to do heat insulation on the roof? Or is the air gap between the metal roof and our false ceiling sufficient?

If yes, do you know of any reliable specialist that is able to do this kind of work?

In addition, we would be installing ceiling exhaust fans in 2 toilets. My contractor says it suffices for the air to be blown into the roof, and that there is no need to have the ventilated air blown outside the building. Is this acceptable especially in the long run? Am wondering where the ventilated air with moisture from the toilets is going to go when its in the roof?

Thanks much!

Used to stay at the top floor of a condo. I don't feel the heat but had an issue (which was resolved) with the management over the waterproofing of the roof coz my false ceiling had a yellow patch.

Hi joshdes,

Did you know if the roof had any insulation under it? Or was it bare metal like mine? Thanks!

If I remember it right, no insulation coz the workers injected some chemical into the concrete.
