What Is Decking on a Roof

WHAT IS ROOF DECKING? Roof decking, also known as sheathing, is the boards that fill the spaces between the roof’s structural components, such as trusses and joists. Decking provides a flat plane to which shingles can be fastened and workers can use as a path.

Is roof decking necessary?

Roof decking is the foundation that keeps your shingles supported. Sound, high-quality roof decking is essential to keeping your house dry and your roof in great shape.

How do I know if my roof deck needs replacing?

  1. Visible holes in your roof.
  2. Signs of mold or mildew in your attic.
  3. Missing shingles.
  4. Roof sagging that’s visible from the exterior or interior.
  5. Curling and/or buckling shingles.
  6. Shingles that are wearing in a granular pattern.
