This topic was somewhat covered in my other thread about a new shop, but I wanted some more opinions.

While I have helped build a couple barns none of them have had metal roofs

I was wondering which is preferred, I know that you would need double the trusses (2' OC instead of 4') and then sheet it but then threre is no risck of condesation (indoor rain as some call it) I don't know how bad the condensation problem can be since I have never used a barn with metal roof.

Which would you go with: metal or shingles??
