shed vapour varrier

    hello,
    i have just finished building my steel shed from box iron and box profile sheeting.
    i have finished the inside of the shed with 25mm insulation board (xtratherm) and 12mm plywood.
    i also put insulation on the roof.
    my problem is that vapour condensates between the steel roof ( which has anti drip backing ) then flows along the insulation until it meets a gap then flows out onto the floor.
    if i removed the steel roof sheets and then roll out a vapour barrier material and refit the roof, would this solve the problem?
    many thanks in advance!

    i take it you plied the roof first then insulated if then the roof cladding if so your vapour barrier should be after the ply then insulation then the finished roof
    hope this helps

    8 inch roof joists,then covered over with Daltex Ultra breathable roofing membrane,then battoned over,then cladded in "non drip" tile effect cladding.Just like a normal tile roof would be done.

    No water ingress,leaks or condensation.
