EPDM warm-deck flat roof · 2025
Kitchen extension flat roof
A new open-plan kitchen extension needed a flat roof that would never leak over the family’s brand-new island. We built a warm-deck with 120mm insulation, tapered firrings for a clean fall, and a single sheet of EPDM rubber dressed into a powder-coated aluminium trim.
