What type of material is considered non-nailable?

• A. Wood
• B. Concrete
• C. Plywood
• D. OSB

Answer: (B)

Concrete is considered non-nailable because it does not have the requisite structural properties to accommodate nails effectively. Instead, concrete surfaces typically require fasteners designed for masonry, such as screws or anchors, which can penetrate the solid mass of the concrete. Wood, plywood, and oriented strand board (OSB) are all nailable materials. They are designed to allow for the insertion of nails, which can hold roofing and other materials securely in place. These materials feature the necessary fibrous structure to support the mechanical fastening through nails, making them ideal for typical roofing applications.
