See for yourself.

A leaking flat roof poses a serious problem for the owner, because the penetrating moisture damages the entire roof structure in the long term and can lead to increased operating costs, incalculable restructuring costs and even total failure of the building. Professional inventory & cataloguing helps to always keep an eye on change and to be prepared for the worst case scenario.
