The lignin is a natural glue within timber that binds its cells together. When the lignin is destroyed this is known as chemical delignification. If this happens the timber structure will gradually weaken and eventually fail. The roof battens are normally first to be infected/ damaged which may cause tiled roofs to collapse over time. If you encounter chemical delignification in your roof space, please be aware that it is very dangerous to walk on the roof exterior as this is known as a Structural Pest.
