I've attached a picture (not the best), but you can see the board I'm referring to peeking out of the insulation. The joists run left to right in relation to the point of view of this picture and this board is attached to the top of the joists and runs perpendicular.
Is that board peeking through structural? I'm asking because it runs over top of my attic opening and I wondered if I could just cut it off between the two joists.
There's also a barely visible board that goes up at an angle in front of the attic vent (you can kind of see the shadow of it in front of the attic vent. What is that one and is it structural?
