When is solid roof sheathing recommended for shakes and wood shingles?

Solid roof sheathing is recommended for shakes and wood shingles when the outside temperature is zero degrees Fahrenheit or colder due to the specific characteristics and requirements of these materials in cold weather. At these low temperatures, the potential for ice and moisture buildup increases, which can lead to complications like water infiltration and ice dam formation. Solid sheathing provides a solid, continuous surface that contributes to the structural integrity and helps minimize air leaks and moisture issues beneath the roofing material.

This solid surface also aids in the proper installation of shakes and shingles, which need to be securely fastened to ensure they perform optimally. Other weather conditions may also affect the performance of the roofing materials, but the crucial aspect during very cold temperatures is to provide a stable and secure base that protects against problems associated with fluctuating temperatures and increased moisture levels. Thus, ensuring that the sheathing is solid in extremely cold weather is essential for the long-term performance of shingles and shakes.
