Roofs and roof terraces are the parts of a building that are most exposed to the weather and other atmospheric influences. Even minor cracks in the roof covering can result in water ingress, which can endanger the structure of the building over time. Standing water and moisture also encourage the growth of microorganisms, such as lichens, and the spread of mould. This has a negative impact on the building’s lifespan and living comfort. For this reason, effective waterproofing and protection of roofs is essential.
