A warm roof is simply a roof with insulation that has been laid on top of the roofing deck, a vapour barrier always accompanies the insulation to prevent the moisture within a building penetrating the insulation
This means it completely eliminates the roof getting condensation problems in the future. It is a requirement of building control to have a warm roof installed wherever possible to the preferred depth of 120mm.
In some cases this simply isn’t possible and this will have to be reduced but this will lower the U value of a building.
Every flat roof we install will come with new insulation which will increase the
roof height, this also means new fascias will need to be installed to accommodate the increase in height.
