The home's roof insulates the property and prevents inclement weather from damaging your belongings. For older structures, one of the most common roof repair issues is dry rot. This occurs when the wooden supports that hold the roof together start to decay, and in severe cases, it can cause the structure to sag or collapse. Below is more information about this problem to help you spot and prevent it.

How Does It Develop?

The beams and rafters that make up your roofing system are prone to dry rot because they are made of wood. This type of deterioration is often caused by the fungus Serpula lacrymans. This growth often remains dormant in the timber until there is enough moisture present for it to grow and spread. While this is similar to mold, it doesn't require much water to trigger growth, which is why the damage it causes is referred to as dry rot. Once the fungus settles into the wood, it breaks down the cellulose fibers that hold the beams together. Eventually, this softens and weakens the wood, increasing the risk of cracks. 

What Are the Signs of Dry Rot?

Dry rot does not occur suddenly, which means it can take a long time for you to notice problems developing. One way to test for this issue is to take a long-handled tool to the attic and prod the wood. If it feels soft or spongy, or pieces start to fall off when you poke it, the fungus may be destroying the beams.

Also, pay attention to any white, gray, or light brown growth on bare wood, as these are common colors of the fungus. Aside from exterior growth, the beams may also appear dry or have visible cracks. This indicates that the issue is progressing to advanced stages, which compromises the safety of the home. Finally, see how the attic smells. If you notice a musty odor in the area, this is a common sign of fungal growth, and a roofing contractor should inspect the structure.

What Are Your Options?

While dry rot is preventable with proper maintenance, roof repairs usually cannot save the structure once it progresses. For example, by insulation the attic properly and patching holes in the roof promptly, you can prevent moisture from feeding the fungus that causes dry rot. If a roofing contractor determines that your beams are compromised, they may recommend investing in a roof replacement to protect the home and prevent future issues.
