Later designs such as the use of selectively permeable membranes are also not immune to the effects of roof vent loft condensation problems.

Although the use of the completely impermeable and the selectively porous roofing styles may cause roof condensation problems it is actually very important and somewhat indispensable. Condensation happens when moisture filled air contacts anything that is below the dew point temperature. Condensation on metal roofs can be a problem once the weather starts to get cold.
