Abstract
Vents and vapor retarders incorporated into roofing systems to prevent moisture from condensing within the roof. The need for vents and vapor retarders in building envelopes depends on the climate of the place, the temperature and moisture conditions within the building, and the type of materials and systems used for the envelope. Most of this paper is concerned with condensation in cold weather, but the warm weather problem is also considered.
