Which of the following is NOT a purpose of a roof deck?

Structural support
Provide waterproofing and moisture control
Aesthetic enhancement
Protection against fire

The correct answer is: Provide waterproofing and moisture control

The option regarding providing waterproofing and moisture control is primarily a function of roofing membranes, underlayment, and other materials applied above the roof deck, rather than the deck itself. The roof deck is designed mainly to provide a strong, stable structure that supports the roofing system, including the weight of roofing materials, snow, rain, and any foot traffic during maintenance. Structural support is essential because it holds the entire roofing system in place and ensures it is resilient against various loads. Aesthetic enhancement relates to how the roof’s overall look can complement a building’s architecture, which may be achieved through the design and materials used on the roof deck and coverings. Protection against fire is also an important consideration in roof design, as certain materials can offer better fire resistance. Thus, while waterproofing and moisture control are critical for the function and longevity of the roofing system, they are not objectives that can be attributed to the roof deck itself.
