I need to replace a window fitted in 1970's that has the joists of a flat roof sitting on top of the frame. A surveyor is telling me that if it was OK in the 1970's (I don't know that it was), then it's OK to replace on the same basis. I'm unconvinced so took counsel from a window fitter who seemed alarmed at this, saying it was unsafe and doesn't meet current standards.
Can anyone bring this debate to a conclusion, preferably by pointing to specific regs?
