Roofing professionals recommend installing vapor retarders on concrete roof decks to control the moisture contained in the concrete and reduce its migration into the roofing system.? The authors will discuss their research into the response of common vapor retarders to the moisture entrapped in the concrete deck.

1. Discuss that moisture is entrapped in concrete roof decks and it will migrate into the applied roofing system.
2. Determine the roll of a vapor retarder in controlling the moisture moving from the concrete roof deck into the roofing system.
3. Evaluate conditions suitable for installing various vapor retarder systems over concrete roof decks.
4. Discuss the author's current research into the performance of vapor retarders applied to concrete roof decks.
