I just had my first Wind Mit with Radiant Barrier hiding the sheathing.
In my opinion, to start opening the radiant barrier in an attempt to find the nail spacing and nail size would be considered intrusive inspecting. I declined to continue the inspection even though the client agreed “I” could open the barrier. I felt there was too much liability on my part to continue, plus I felt responsible to put the barrier back in place as I found it. That was impossible because I don’t carry a staple gun and it’s considerably more work.
What do you do if you encounter this situation?
