What is roof decking?

Roof decking is the base layer of a roof that provides support for the roof covering materials. It is typically made from plywood or oriented strand board (OSB) and is installed over the roof trusses or rafters.

Roof decking plays a crucial role in the structural integrity of a roof, as it helps distribute the weight of the roof covering materials, snow, and other loads evenly across the roof framing. It also helps prevent water penetration and provides a flat, smooth surface for the roof covering materials to be installed on.

There are different types of roof decking materials available, including plywood, OSB, and wood planks. The choice of decking material will depend on factors such as the local climate, roof design, and budget.

Proper installation and maintenance of roof decking are essential for ensuring the longevity and performance of a roof. Inspecting the decking for any signs of damage, such as rot or water intrusion, is important to prevent further issues with the roof. Regular maintenance and repairs can help extend the life of the roof decking and ensure the overall integrity of the roof structure.
