Hi,
The existing flat roof which was build in 2001 has got plan (attached) saying "warm deck flat roof". Does it mean its warm roof (which has insulation on top now a days)?
When looking from inside through a hole in plasterboard its got thermocol insulation boards (very thin).
The plan is ...
Ply on top of joist
1) vapour barrier
2) Insulationboard
3) OSB boards
4) EPDM rubber
The reason is that I need to know if I need to raise height or not for installing new warm roof (if its not already a warm roof).
Thanks
