Wood shakes should only be used on which type of sheathing?

Wood shakes are a traditional roofing material known for their durability and aesthetic appeal. To maximize their performance and longevity, they should be installed on solid or spaced sheathing. Solid sheathing offers a continuous, stable surface that helps to provide adequate support for the shakes and allows for proper ventilation beneath the roofing system.

Spaced sheathing, which consists of individual boards spaced apart, also permits air circulation, helping in moisture control and reducing the likelihood of rot or mold developing under the roofing material. This ventilation is crucial for wood shakes, as wood can be susceptible to degradation if trapped moisture is unable to escape.

Other types of sheathing, such as composite, plywood, or open sheathing, may not provide the same benefits or support needed for wooden shakes. Composite sheathing might not offer the same natural venting properties, while plywood can be prone to swelling or water damage without appropriate air flow. Open sheathing, which lacks solid support, can lead to inadequate performance of wood shakes, compromising the roof’s overall integrity and resistance to weather elements. Therefore, using wood shakes on solid or spaced sheathing ensures optimal functionality and longevity of the roof.
