A roofing system includes a plurality of insulation boards adapted for overlying a roof deck to form a layer of insulation, and a plurality of cover boards adapted for overlying the layer of insulation. Each insulation board includes a foam material that includes polyisocyanurate or polyurethane, the foam material having a first density. Each cover board includes a material including polyisocyanurate or polyurethane, the material having a second density greater than the first. The roofing system may further include a waterproofing membrane adapted for overlying the cover boards. The insulation boards and cover boards may include facers on top or bottom surfaces.
