I have new house ready to go and planning on 5V 26 ga Galvalume.. Location = Upstate SC .
Roof sheathing is 1/2" OSB with Titanium over it which is most typical for this area . My roofer wants to use bubble warp over the titanium just to make sure that the button heads that hold down the titanium do not show through the flat part of the 5V 26 ga panels...
Just looking for quick opinion , bubble wrap on top of the titanium or not ? Thanks so much !!

Bubble wrap or no bubble wrap depends on air space. If he is putting the metal directly on top of the bubble wrap, that negates the radiant barrier effect.
It needs and air space to work optimally.
