Hot Roof Vs Cold Roof

A cold roof is best when you re initially creating a flat roof and is cheaper than a warm roof but does provide an inferior thermal performance. In cold roofs the outside air is allowed to freely flow under the roof sheathing. Cold roof construction requires that a suitable ventilated air space exists above the insulation layer within which the air is constantly mobile being replenished by fresh incoming air whilst the air resident within the void space is being expelled via a natural vent action at another point.

In hot roofs the insulation is typically installed close to the roof sheathing but the main characteristic is the space under the sheathing is closed to fresh air flow.

A warm roof is much more straightforward to install and provides a superior thermal performance and is therefore more costly. So what kind of difference does this make. Namely the insulation layers. Thus your unventilated roof is indeed a hot roof.
