What is Dry Rot?

Dry rot is a type of wood decay that is caused by fungi in certain areas of the roof where there is too much moisture content. Dry rot thrives when there are certain enabling conditions such as moisture, warmth, and wood. The fungus can lay bare for long on a roof as it is airborne. It multiplies at a very fast rate and could cause greater damage to the whole roof if not urgently treated. 

Unlike wood rot which is caused by moisture alone, dry rot can be caused by small amounts of moisture. As the fungi start growing, their spores start attacking the wood fiber, splitting it until the wood is soft.
