When it comes to roof health, the first thing that may come to mind is your shingles. However, it doesn’t stop there. Below your shingles is a structural component known as roof decking or sheathing. It is the foundation of your roofing system that connects the roof to your house. The roof decking lays on top of the structural trusses to cover the rafters and support the weight of your roof shingles.

Repair Rotted Roof Decking

The decking may not be visible, but it’s one of the most crucial components of your roof. If it suffers rot, simple repairs may not be enough.

How Can Roof Decking Get Damaged?

Roof decking is generally made from plywood or plywood composite known as oriented strand board (OSB). Since it’s made from wood, roof decking is susceptible to rot and water damage, especially if it’s constantly exposed to sustained or excess moisture.

Water can seep into your roof in different ways. During the winter season, poor attic ventilation can cause ice dams and allow water to slowly make its way into your roofing system and cause rot to develop on the decking. Clogged roof gutters and downspouts are also unable to direct water away from your property and contribute to the water buildup.

Leaks are among the most common signs of damaged roof decking. Leaks can lead to ceiling spots, stains on interior walls, or peeling wallpaper. If left unaddressed, mold and mildew can develop and cause health issues. A sagging roof is also another sign of roof decking rot. Once the water has penetrated your roof, soaked decking can warp and make your ceiling or roofline look bowed or wavy.

Should You Repair or Replace Rotted Roof Decking?

If you think your roof decking has rot damage, you need to call a professional roofing company for an inspection. If they find signs of rot, they’ll recommend replacing the entire decking since simple repairs may no longer cut it. A roof decking that isn’t replaced promptly can lead to more costly repairs and mold issues.

While a roof replacement may seem like a costly undertaking, it’s a smart investment. Replacing your damaged, rotted roof with a brand new one prevents further damage and ensures that your home’s structural integrity is free from moisture issues such as waterlogged framing or joists.
