Flat roof design going wrong. Who is responsible for your flat roof design?

Who designed your flat roof? The Builders, Roofers, Architects, Structural Engineers, an agent? Confused? Any design shoud be detailed and have all the drawings and specifications so that the builder can build with confidence. Unfortunately, it appears that this is seldom the case. Most drawings or plans I find on site have just enough details to get the job through planning and building control; design details are just not there. This becomes very apparent when it comes to flat roofs and vapour control layers. A basic generic drawing is shown with some written details next to it. If you are lucky, the mention of a vapour barrier will be there but not what type. Roof insulation thickness is often there, and a supplier's brand name. Often different brands are used as they are cheaper than those specified. I think I know the answer, but I'm going to keep it for another video.
The biggest problem I'm finding with new flat roofs in London is, after two or three years, the decking is rotting from the inside out. Black mould, fungus and rotting timbers are all to be found once we open up the roof and do an inspection. This is found on large and small flat roofs; flat roofs that have been designed and overlooked by teams of engineers, architects and surveyors. I think we have a ticking timebomb on our hands; the more we insulate our houses and buildings the bigger the problem gets.
