1. What is the primary purpose of installing a vapor barrier within a roofing
assembly on a commercial building project?
, A. To increase the structural load capacity of the roof deck
B. To prevent moisture migration into the insulation and building interior
C. To improve the fire resistance rating of the entire roof system
D. To provide additional wind uplift resistance for membrane attachment
Correct Answer: B
Explanation:
Choice A: Vapor barriers do not enhance structural load capacity; they serve
moisture control functions.
Choice B: Vapor barriers prevent warm, moist interior air from migrating
upward into insulation where condensation can occur.
Choice C: Fire ratings are achieved through specific assembly components
and testing, not vapor barriers.
Choice D: Wind uplift resistance is provided by attachment methods and
fasteners, not vapor barriers.
