The compatibility of plywood for solid sheet sheathing with roofing materials is indeed confirmed as being compatible with both shakes and shingles. Plywood sheathing provides a sturdy and stable base that is essential for the installation of various roofing materials. Its surface allows for proper adhesion and support, which is crucial in extending the lifespan and performance of the roof.

When using roofing materials such as asphalt shingles, plywood effectively contributes to a smooth and even substrate, promoting better weather resistance and durability. Similarly, when wooden shakes are applied, the plywood offers a solid backing that helps maintain structural integrity and prevents issues like warping or cracking of the shakes due to moisture absorption.

Both types of roofing materials benefit from this compatibility, ensuring that the installation process is efficient and that the finished roof provides optimal protection against the elements. Thus, plywood is versatile enough to be an effective substrate for both shakes and shingles.
