Chemical Delignification damage is most commonly found in timber sections used as roof tile battens of buildings that are located in close proximity to the sea, or major roads that have heavy traffic. In our experience, terracotta tiled roofs are more prone to Chemical Delignification to the timbers due to the porosity of the terracotta tiles that puts the battens through a wetting and drying cycle.
Does this mean that your home is structurally unsound or defected if delignification is visible?
