Pete did mention polycarbonate MB ….the sheet comes in many thicknesses from 6 mm to 32 mm and have multi wall profile for his roof 16 mm twin wall would do it or 20 mm triple wall is what I would use , in the event of hail that we get over here ( at present ) golf ball size may dent the sheet but zero chance of penetrating the sheet , the profile is like looking at a mouth Organ reeds some look like pyramids ….the standards here are 28 mm for polycarbonate there is one other product that’s 70 mm thick .
