Entire Roof Deck Coverage

GAF-Elk's Leak Barriers Sweepstakes
Q: Can leak barriers be used for entire roof deck coverage?

Full deck coverage is a great option where concerns about storms or severe weather damage are heightened. However, special considerations must be made in these instances. A design professional must address the potential for moisture entrapment, excessive moisture build up, and condensation. In designing a proper moisture control system, many factors, including building use and moisture sources, as well as expected inside and outside temperatures, and relative humidities must be taken into consideration. Moisture control solutions may include, but are not limited to use of: a continuous vapor barrier in the ceiling; soffit, fascia, and ridge vents; gable vents; and power vents.
