You'd be surprised. Better to be safe than sorry in my estimation and the last thing you want is something getting up there and dying too.
I am going to put an exposed fastener metal roof on my shop.
I intend to do this over cross-battens.
I have seen some suggestions that this should be detailed to include insect screening similar to a rainscreen application under siding.
However, I am wondering if it really makes sense to include this detail. The panels must get extraordinarily hot in the summer and I imagine this would be a very hostile environment for insects (such as wasps).
I would appreciate any comments on this.
