Condensation in a flat roof is a common problem in cooler climates that can often be mistaken for a leak in the roof membrane.

We need to utilize strategies to prevent condensation, either by warming the condensing surface, by controlling vapor diffusion and air leakage, or by controlling interior relative humidity levels.
