I suggest you use a light weight roofing material, like Suntuff Polycarbonate panels, which are sold at Bunnings. Much lighter than metal, can be cut with jig saws, and also comes with a 15 year warranty. Suppose to be hail resistant. I have these on my roll off roof, and it is very light to move. You can easily insulate under the panels with thin foam panels, or aluminium bath type insulation. I used foil batts.
In a design like you propose, you will need some sort of counter balance (other than just a rope) to keep the panel structure from slamming down once it reaches tipping point. Maybe a gas strut would work.
Also consider the ridge cap sealing. You can buy corrugated plastic foam pieces that can seal the corrugations against wind and water being pushed in at the ridge. I used these on my roof peak, again Bunnings has them.
Good luck
