Replacing Flat roof, told insulation upgrade needed
Discussion
Had a quote to replace a flat roof and was told that it needs to have 130mm of insulation added. As this is effectively just replacing what is already there can someone explain why the insulation is needed.
I understand adding insulation is good but it appears the flat roof cannot be replaced without doing the insulation work and I would like to understand what is driving this.
Any help appreciated.

The roof is a large flat roof covering a loft conversion in a bungalow, from what has been said replacing the whole thing is classed as a renovation and not a repair which means the structure has to be brought up to the latest building regs for insulation.
During the initial conversion probably late 70's the council restricted the flat roof height to be no higher than the peak of the pitched roof so adding the extra insulation would breach this limitation. Apparently the council are okay with breaking the height limit to get the insulation in there.
As it turns out the leak that prompted the replacement quote was actually a loose flashing on the chimney which was fixed for £80 and he even fixed the front wall which someone had knocked over, top bloke.
Thanks to ph for answering the query :-)
