The roof should incorporate insulation and usually a vapour control layer to protect from interstitial condensation.
Large amount of water vapour can evaporate from reinforced concrete or a wet screed.
The simplest way to construct a roof terrace is by utilising a concrete slab.
Once the waterproofing membrane is laid drying out of the structural slab will mostly take.
For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers.
A concrete roof is exactly what it sounds like.
Exact specifications vary but most concrete roofs are several inches thick.
Design and detail together with proper preparation of the substrate are key elements to successful roofing.

This is one of the common causes of flat roof waterproofing failure.

A concrete slab flat roof is normally made up of a structural layer of concrete finished with a smooth screed onto which a water proof layer such as a membrane is laid.
Being trapped between the reinforced concrete roof structure and membrane.
Because typical concrete is porous it needs to be treated with an additive such as xypex which makes the concrete waterproof.
Even though a treated concrete slab is waterproof standing water on a roof terrace should be avoided and so all roof terrace slabs should.
