Hello everyone,

on our garden shed (not insulated) we have a single-pitch roof made of OSB boards, with a layer of roofing felt on top as rain protection.
Now trapezoidal sheets are to be laid there as the final roof.

Can I screw these sheets directly onto the wooden sheathing/roofing felt, or is ventilation needed?
Yes, condensation would certainly dry out better with ventilation, but the roof should actually be quite well protected by the roofing felt.

I have read around on the internet,
but I haven't really gotten any clearer from it...

Has anyone of you done it like this before?
What ideas are there on this?

Thanks for your help!
