Decking

Decking refers to the layer of boards installed over rafters or trusses to form the base of the roofing system. It provides a surface for underlayment and roofing materials. Common materials include plywood and OSB. Decking must be strong and moisture-resistant to prevent warping and structural damage. In coastal climates, proper decking installation is critical for resisting water penetration and maintaining roof integrity.
