Hi Gary, By creating a warm roof to building regs Part L 1b, spec would be felt over concrete (to create a vapour barrier) overlay 150mm rigid insulation (kingsapn tr27 or equivalent to give Uvalue .015 wmk/3) bonded down. Then a waterproofing system i'd recommend EPDM with a 20yr guarantee fitted by someone that knows what they are doing \Rgds \Mick- Approved Rubber Roofing Contractors Ltd
