The answer to 'roof decking or roof decking' is that roof decking and roof sheathing are two different, but related, components of a roof system. Roof decking, also known as roof sheathing, is the structural layer that supports the roofing material and provides a surface for the roofing to be installed on. It is typically made of plywood, oriented strand board (OSB), or sometimes solid wood boards.
The main benefits of roof decking are that it provides a stable, rigid surface for the roofing material, helps distribute the weight of the roof, and can add to the overall structural integrity of the home. Roof decking is an essential component of a roof system and should be installed properly to ensure the roof's longevity and performance.
