The roof decking or sheathing functions as a foundation for the layers of underlay and the shingles on your roof. It also connects the roof to your home’s frame. While this part of your roof isn’t visible, it’s essential to the structure of your home.

What Is the Purpose of a Roof Decking?
The weight of asphalt shingles plus the layers of tar or felt paper between them and the decking can add stress to the roof’s structure. Decking provides support for all the weight on a roofing system. During a storm, it can help your roof withstand damage from fallen debris and weather extremes. Flame retardants are often applied to plywood decking for added protection against fire. Moreover, quality decking can also provide added protection against leaks.
What Happens When You Have a Rotted Decking?
Rotted decking can compromise the structural integrity of your roof. A damaged decking doesn’t provide as much support as a healthy wood. It can’t also safely grip the nails in the roof to keep the system intact. Moisture causes rotting, which makes the wood more likely to absorb moisture. This problem will eventually result in water damage to your attic, ceilings, and walls. You can avoid this issue by getting regular inspections from a professional roofing contractor.
Should You Also Replace Your Decking When Getting a New Roof?
Your roofer can check the condition of your decking either from your attic or once they have removed the old shingles. They will inspect the component for rot and flexing of the boards or when the decking bends when walked on. If any of these issues are present, the decking would need to be replaced.
