A) Enhance thermal insulation
B) Prevent air leakage
C) Reduce condensation within the roofing assembly
D) Act as a secondary waterproofing layer

Answer: C) Reduce condensation within the roofing assembly
Explanation: A vapor retarder is designed to minimize the movement of moisture vapor into roofing systems, which can help prevent condensation and related damage.

2. Which of the following is a common issue caused by improper insulation board installation?

A) Thermal expansion of the membrane
B) Moisture infiltration
C) Ponding water
D) Membrane punctures
