Safety nets for securing roof tiles on church towers, old factory buildings or barns. Somentimes a crumbling roof cannot be repaired immediately. Nevertheless, the owner of a property is responsible for safe traffic routes and work areas. In such cases, safety nets are a temporary solution. The netting gets simply tensed over the affected roof or in front of the affected facade. So the crumbling bricks will be held directly or they will be guided on their way to the ground.
