Your roof is a complex system made of several different components. One of these components is the sheathing. Roof sheathing acts as a foundation for shingles and other roofing materials. Because the sheathing is hidden beneath your roofing materials, it can be challenging to determine when the sheathing needs to be replaced.
Here are three signs that you can watch for when trying to determine when you need to invest in new roof sheathing for your home.
1. Water Damage in the Attic
The attic is a great place to start looking for signs of damage to your roof sheathing. Discoloration on the walls or ceilings in your attic can indicate that your roofing materials have been compromised. As moisture leaks through your roofing materials, it comes into contact with the sheathing. Sheathing can absorb this moisture over time. It's essential that you contact an experienced roofing contractor to replace your sheathing as soon as you spot evidence of water damage. Any delays could result in serious structural damage to your home.
2. Sagging Spots on the Roof
A visual inspection of your roof can reveal a lot of information about the condition of your roof sheathing. Wood rot is a problem that can plague sheathing when your roofing materials are compromised. Moisture that collects within the sheathing itself can cause the wood to become soft. This softening of the wood leaves sheathing unable to properly support the weight of your roofing materials.
If you see any sagging spots on your roof, you can bet that damaged sheathing is to blame. An experienced roofer can replace the sheathing that has been affected by wood rot to restore the integrity of your roof.
3. Mold Growth in Your Attic
Moisture that comes into contact with your roof sheathing has the potential to fuel mold growth in your attic. Mold thrives in dark, moist environments. A leaking roof can lead to saturated sheathing, which will almost always lead to mold growth.
Exposure to certain types of mold can be dangerous for your family. Once damaged sheathing has sparked mold growth, the mold will likely spread through your home's ceilings and walls. This mold spread can cause serious respiratory health issues in your home. A reputable roofing contractor will be able to replace any of your sheathing that has been exposed to moisture so that you can prevent mold growth inside your home.
