Where should roof sheathing be stored on the roof prior to installation?

Storing roof sheathing over a load-bearing wall is the best practice because it ensures that the weight of the materials is supported by the structural framework designed to carry such loads. Load-bearing walls are specifically engineered to handle additional weight, reducing the risk of any strain or damage to the roof structure during installation.

This method of storage also helps maintain safety on the job site. By placing the sheathing in a location that has adequate support, it minimizes the chance of shifting or collapsing, which can pose hazards to workers. Additionally, storing materials strategically over load-bearing walls can facilitate easier access and transport during the installation process, increasing overall efficiency.

The other choices, such as placing materials at the ridge or in specific percentages of the roof, could potentially lead to imbalance and structural issues, as these areas might not provide the necessary support required for the weight of the sheathing.
