What is an acceptable method for securing roof sheathing?

Using a combination of screws and nails to secure roof sheathing is recognized as the most effective method due to the distinct advantages each fastening method provides. Screws typically offer superior holding power and resistance to pull-out forces, which is particularly beneficial in applications where movement or vibration could occur. This can enhance the overall integrity of the roof system.

Nails, on the other hand, tend to be faster to install and can provide some flexibility, allowing for slight movement without breaking. This is important in accommodating natural expansion and contraction of building materials due to changes in temperature and humidity.

Combining these two methods ensures that the roof sheathing is firmly secured while benefiting from the strengths of each fastening method. This hybrid approach adheres to construction best practices, ensuring the sheathing can withstand various stresses and loads over its lifespan.

The other methods are less optimal. Using screws only may involve a longer installation process, and while they are strong, they may not allow as much flexibility. Using nails only could increase the risk of loosening over time under certain conditions. Relying solely on adhesive could compromise the structural integrity if the adhesive breaks down over time or is insufficient on its own without mechanical fasteners. Therefore, the combined approach provides a robust solution for roofing applications
