Abstract: The disclosure relates to a roofing system for a flat roof or a flat inclined roof of a building with a thermal and/or acoustic insulation, consisting of a structural support, a deck, optionally a vapour control layer, a waterproof membrane and at least one insulation element being a bonded mineral fibre product made of mineral fibres, preferably stone wool fibres, and a cured aqueous binder, whereby the cured aqueous binder prior to curing comprises a component (i) in form of one or more oxidized lignins, a component (ii) in form of one or more cross-linkers, a component (iii) in form of one or more plasticizers, and whereby the insulation element has a bulk density between 70 kg/m3 and 250 kg/m 3.
