A self-adhesive SBS vapor barrier 10 is also installed between the insulation layer and the profiled steel sheet. The waterproof layer uses PVC waterproof membrane or TPO waterproof membrane. The profiled steel sheet has a corrugated or wave-shaped structure. The anchoring base is inserted into the flexible roof at its center, with its lower part resting on the bottom surface of the profiled steel sheet (the bottom surface of the wave crest, which is not affected by the original building roof), and its upper part resting on the top surface of the waterproof layer, thereby anchoring the steel sheet.
