What are cold roofs and warm roofs?

Home Questions and answers About cold roofs/warm roofs

In contrast to a warm roof, a cold roof has a ventilated channel between the roof covering and the thermal insulation (see roof structure).

A warm roof is a roof structure without a ventilated channel between the roof substructure and the roof covering.
