The only reason you have condensation is lack of ventilation !! You have to make sure there is some type of air movement in the shed, old skool method was drilling some holes through some brick on the bottom of the shed and some small ventilation gaps at the top in the shed, this provides some very light airflow and clears the condensation.
I made our barn roof from it and it's amazing. On boiling hot days it feels lovely and cool and never a drop of condensation in winter. Good soundproofing and very strong to walk across whilst also light enough to man handle.
