What is a primary advantage of using spaced sheathing for roofing?

Using spaced sheathing for roofing offers several significant benefits, with the primary advantage being that it facilitates airflow for drying. This design involves leaving gaps between sheathing boards, which promotes ventilation in the roofing system. This airflow is essential for managing moisture that can accumulate beneath the roofing materials, reducing the risk of mold, rot, and other moisture-related issues. Proper ventilation helps keep the roofing structure dry and extends the lifespan of both the roofing materials and the roof itself.

While some may consider the potential for heavier roofing materials or reduced installation time as beneficial features, they do not directly address the primary concern of moisture management and its implications on the integrity of the roofing system. Similarly, while greater insulation is an important aspect of roofing, spaced sheathing mainly focuses on ventilation rather than providing insulation. Thus, the advantage of airflow and moisture control stands out as the most critical reason for utilizing spaced sheathing in roofing applications.
