Stopping condensation in a metal/tin shelter?

So having successfully now converted the "glorified shelter" into decent looking stables we now have another problem.
We have a constant drip from condensation running along the roof inside.

The stables roofing is corrugated tin sheet with wooden beams underneath, we have filled in any leaks and covered the roof in Bitumen(tar) to seal it off. The roofing is sloped downhill but the condensation inside is dripping directly into the stables, and we are wanting to keep the stables pretty bone dry if possible.

Anybody got any ideas?
We have thought of putting polypropylene sheets in the space between the beams and the roofing itself and any drips will run down the plastic and outside to the guttering... but there must be an easier way? Other must have had this issue?
 
An internal lining layer of sterling board will solve the condensation issue. Onduline roofing suffers the same problem if not lined, which is due to the temperature gradient.

The pics show my field shelter under construction, with its lined roof. A lining can be added as a retrofit option.



 
Thanks very much guys! So the key is to either line with something or to replace with poly.... which I don't want to do unless I win the lottery!! Mortgages are painful things I've found out!
Any other ideas are welcome!! Thanks for the pictures tiddlypom!
 
Lots of ventilation then: remove as much vertical cladding as is practical, yes it will be cold, and you will probably need to rug even the hairy ones. However, it is healthier. Horses should not be kept in a damp atmosphere, and of course they will be producing warm wet air continuously. Cattle sheds often have vertical slatted boarding [Yorkshire boarding], and high roofs, which help eliminate the very real risk of pneumonia in sheep and cattle.

Thanks very much for these! Ventilation isn't bad as one of the stables has an additional door that opens into the field and the roofs aren't "shut" as such they have a gap between the roof and the sides. - Also hoping not to be stabling "a lot" once he moves, would prefer him to be living out 24/7 naturally and having the option to come in :)
I wonder.... is there such as thing like loft insulation? That could be used on the inside of the tin sheets in a stable?

I think perhaps any insulation will absorb the wet and go soggy then mouldy. If it doesn't absorb it then the condensation will continue to form and drip.
 
You mean you have panels that look like this (but more overlapping) in cross-section?

And they drip down where the !s are?
Might be worth looking at something to channel the drips to the side - local handyman job?
 
Insulating is the only answer in the long run its a well known problem with a lot of sheeting on roofs on the farm we use spray on foam to help cut it down . I hate to tell you this though having put black bitumen on will have made it worse. The only form of roofing sheet that suffers very little from condensation is fibre cement.
Contrary to what others suggest insulation does work because it cuts out the exposure to the cold metal sheeting of the damp air it wont go soggy .If you want a really cheap way wire netting with a layer of straw was the old way of doing it.
 
Rigid insulation board would form a barrier and is light thus easy to fix, but if in reach of horses might get eaten! Face it with a thin sheet of ply?

Not cheap cheap but quite easy to do. (Celotex a decent brand, about £21 an 8x4 1" sheet,
