What is the typical spacing for wood shingles on spaced board sheathing?

The typical spacing for wood shingles on spaced board sheathing is a board size of 1 x 4 inches. This dimension allows for proper ventilation and drainage while ensuring adequate support for the shingles. Using 1 x 4s provides a suitable balance between structural integrity and aesthetic appearance.

Wood shingles require specific spacing to perform optimally, as this affects their lifespan and the overall integrity of the roofing. Boards that are too narrow might not provide sufficient support, while those that are too wide could lead to issues with moisture accumulation and inadequate ventilation beneath the shingles.

In various construction practices, the choice of wood board dimension is essential, and 1 x 4s have been established as the standard for this application due to their effectiveness in supporting the shingles while facilitating necessary airflow.
