Which materials can be part of the components for nailable decks?

The correct choice indicates that metal flashing pieces can be included in the components used for nailable decks. Nailable decks are typically constructed to accommodate various roofing materials and provide a solid base for them. Metal flashings are essential in roofing systems because they provide critical transitions and terminations at edges, penetrations, and other areas where the roofing material must be sealed and waterproofed.

Flashings are designed to direct water away from vulnerable areas and help prevent leaks. Their compatibility with the nailable deck makes them a vital component in the overall integrity of the roofing assembly.

Other choices do not directly pertain to the nailable deck components as effectively as metal flashings. For instance, while insulation boards and plywood are common materials in roofing systems, they do not serve the same structural and protective functions as metal flashings when it comes to sealing edges. Vented sheathing is specific to ventilation rather than the nailing surface, and materials like EPDM rubber and bitumen pertain more to the roofing membrane rather than the structural deck itself.
