Roof almost ready to go on our outhouse/shed so looking to see what alternatives are out there instead of plain corrugated pvc coated sheeting.
The shed has been build with an eye to using it as a hair/treatment salon for the missus on the side and so has been built accordingly and I don't want to skimp on the roof now either.

Since you will have people wearing no clothes it will need to be warm. 200mm kingspan minimum.

Will it be continuously or occasionally heated?

Do you have a particular weight limit?

What do you have in place so far? Are the rafters sheeted, and on inside, outside or both?

You could roof it in a Tile something like Tegral. Not too heavy and looks very well. You need to decide what your going to do before the Roof Timbers go on. As the Dimensions and spacing's may change to suit the top layer.

Just have the roof trusses on. No laths yet or felt.

Pitch?

I had this gusclad stuff recommended to me for that type of structure.

My amateur opinion is that an externally insulated roof is easier to get right as the structural timbers are inside the conditioned space and there are fewer cold bridges, so I'm going for Gutex Ultratherm with a proclima Solitex Plus membrane for my own project which has a 31 degree pitch. Haven't made a final decision on the tiling though.
