I have an idea for the roof that I am yet to try out.
Use the light corrugated plastic sheeting.
Apply a coat of polyurethane gradually across the sheet while gradually adhering a sheet of reflective aluminium. So as to inbed the ali. Cover the ali sheet with a second coat of polyurethane.
The finished sheet reflects sunlight and the aluminium sheet is protected inside the shed. And the roof is lightweight.

What do you reckon?

I suggest the Coghlans Emergency Blanket - aluminised polyester 1.3x2.1m
I bought years ago from BCF for about $10each.

Could using cooking foil?

I had a colourbond r/o/roff roof and used 10mm polystyrene foam adhered to it inside. I could feel the heat coming thru but it still made a big difference. I'll likely try 15 or 20mm next time.

Does the foilboard applied on the exterior have adequate longevity?

Cheers
