Water – getting a lot of condensation in new shed

roofshedwater

I just got a new shed built with concrete blocks and a metal roof last month and thing is dripping with condensation from the roof. There is absolutely no insulation in the shed.

How would I get rid of this, insulate the metal roof with spray foam or the normal kind? Plaster the inside and outside of the shed?

Because the roof is metal it will get cold and when the (relatively) warm damp air inside the shed comes into contact with it, condensation forms.

You need to make sure that there is a thermal barrier between the inside surface of the roof and the outside surface.

So any of the things you suggest would do, but might cause ventilation problems (say). So a false ceiling would probably work best.
