What is the maximum width for boards used in solid roof sheathing?

The maximum width for boards used in solid roof sheathing is 1 x 6. This specification is based on building codes and regulations which dictate that for structural integrity and proper support, sheathing boards should not exceed a certain width. Sheathing is critical for the roof's stability, insulation, and to provide a proper surface for the roofing material.

When boards are wider, they can lead to issues such as warping or insufficient loading support, as well as challenges in proper installation. Using boards wider than 1 x 6 could compromise the roof’s strength and the overall integrity of the structure, which is why it is essential to adhere to the prescribed maximum width for solid roof sheathing.
