Best barn roofing material....?

[popeye151]

Anyone got any opinions or advice? I'm gonna be building a 60x30ft barn and can't quite decide.

Don't like box profile as the fixings go in the 'valley'. Seems like your putting a hole in the worst possible place, then relying on the rubber washer to keep water out.

I like corrugated tin but there's issues with condensation. Has anyone used the non-drip backing stuff? Is it a load of rubbish?

Fibre cement. Not ever used this. Seems like the most common material and has no condensation issues. But I've heard it's fiddly fitting it as you have to cut off the corner that over laps () and they come in shorter lengths.

Any thoughts. I'm swinging for corrugated tin.

if you don't like the idea of fibre cement, it has to be box profile, as you can get the sheets long enough to reach the ridge without joins, but if the shed is for animals, has to be fibre cement.

60x30 fibre cement, two good blokes would have that on by lunch time!

It's going to have a bit of everything. We got a few cows, so one bay will be for them. The rest will be machinery, workshop, lambing etc

Fibre cement is by far the best option for what you are planning to use it for, the mitre cuts are simple once you’ve got your head round it.

I prefer metal as you always have the fragile roof hazard with fiber cement.

I think condensation would happen with any metal roof - but it only happens in specific weather conditions. It's not an issue if you have metal purlins and decent ventilation.

Think we used corrugated for the last shed roof but that's only because it was a shorter run and was more readily available than anything else.
