The answer to 'what causes roof decking' is roof decking, also known as sheathing, is the structural foundation of a roof that supports the roofing materials like shingles, tiles, or metal. Roof decking is typically made of plywood, oriented strand board (OSB), or solid wood boards that are nailed or screwed to the roof trusses or rafters. Proper installation and maintenance of the roof decking is essential for the overall integrity and longevity of the roof system.
Common causes of roof decking issues include water damage from leaks, rot from prolonged exposure to moisture, warping or cupping due to temperature changes, and structural damage from heavy loads like snow or debris. Identifying and addressing these problems early can help prevent more extensive and costly roof repairs down the line.
