In my opinion – the best is PVC single ply roofing membrane (IB, Soprema, Fibertite). IB is the only one to my knowledge that has Residential material warranty (lifetime).
Stay away from rubber / tar / bitumen … Also I’d not do TPO ..
Method – I’d say mechanically attached over 1-3" of rigid insulation.
Hope this helps – let me know if you have other questions. Leo
