The answer to 'roof decking worn out' is that the plywood or boards that make up the roof's surface have become damaged, worn, or rotted over time. This can lead to sagging, leaks, and even structural issues if left unaddressed. Common causes include weathering, water damage, and age-related deterioration.
Some key signs of worn-out roof decking include visible sagging or uneven areas, soft or spongy spots, and water stains or mold growth. If the decking is in poor condition, it's important to address it promptly to prevent further damage to the roof and home.
