A plank deck in roofing refers to a flat wood deck constructed from individual planks. This type of deck serves as a solid base for roofing materials and provides structural support for the entire roof system. The planks are typically laid down horizontally and are fastened together to create a continuous surface, which is crucial for the installation of various roofing components.

Using a wooden plank deck can offer advantages such as ease of installation and the ability to work with various roofing materials, making it a common choice in residential roofing applications. This choice provides a robust framework for both sloped and flat roofs, allowing for the proper installation of insulation, underlayment, and shingles or other roof coverings.

While other options refer to different roofing materials or components that may be used in combination with the plank deck, they do not accurately define what a plank deck itself is. The distinction is important for understanding the various elements involved in roofing construction and how they interact within the overall roofing system.
