tin roof on garage has condesation inside can i fix it

I just think you are spending money for an inferior roof. When we built the stables I came to the conclusion that the bitumen roof's were just not built to last and could become brittle overtime.

Now with 2 horses and 25 chickens I have a lot of condensation at this time of year even with very good airflow. It is not really a problem except in the tackroom and I really should make a ceiling with OSB.

If I were you I would look at OSB or investigate thin insulating boards.

The assumption I am making is that the roof is sound and will last a number of years.

The OP hasn't given any indication that the roof is failed or leaking, (unless I missed it), it's just behaving like any other corrugated steel roof would if the garage gets warm and moist. If it doesn't need replacing then insulation is the answer. It may even be the plasticoated steel pressed sheets used in commercial roofs, they are cheap and readily available today, and are a viable solution for any out building/garage/stable etc given they are insulated if there is a need?

thankyou going to look into this further, will check out the insulation idea
thanks again

i was thinking if i first put the bitumen corrugated roof on, then put back the tin roof on top, would that not work? the bitumen work as a insulation underneath?

You'll have to watch the weight - if the roof was built to support a fairly light tin roof, adding the weight of bitumen sheets might be too much for your roof supports.

You might find ventilating the garage would help - small cheap fan, like a bathroom type, will help pull the moisture out.

I had the same problem as the OP. What I did was get a suspended ceiling constructed with insulation material. It works really well - very pleased with it. It cost me ~£650 for a large single garage about two years ago.

As per my post #6, where's the smug git emoticon???

But seriously. this is the only way in a warm room with a cold roof, :T:T

i have attached some pics, the tin roof is supported by metal beams, so i recken they could handle the bitumen roofing as well.
the garage at the moment is just used for storage, as i have to cover it all up with plastic sheeting as it gets wet, one of the pics shows the condensation inside on the roof.
