Warm roofs and cold roofs: the main difference
The position of the insulation is the main distinction. A warm roof places insulation above the structural deck. A cold roof usually has insulation below the deck, with ventilation and moisture control needing careful attention.
Choosing a suitable roof construction
Neither approach should be selected from a label alone. Existing roof levels, door thresholds, drainage, the supporting structure and the use of the rooms below all affect the design. A warm roof can raise the finished roof level, so junctions and access points must be checked before work starts.
Replacing an existing flat roof
A roof assessment should consider the deck condition, insulation, moisture, waterproofing and roof-edge details together. The specification should suit the particular building and any applicable approval requirements.
