I am hoping someone can answer why I have multiple trusses nailed into the top plate of a small interior wall in my home. In the first image, I have highlighted in red where the trusses actually touch, and are nailed into the top plate of the interior wall. I was under the impression that trusses should not even touch the interior wall. Can someone please explain? I do no believe this wall is load bearing, as the adjacent trusses in the living room would also need to be supported if support were needed.
In the second image, it is hard to see. But That is a picture in the attic of one of the trusses nailed into the top plate.
