I'm re-framing a portion of a wall on my aged, many-times added-onto single-story house to put in a modern 6X5 window instead of several single-pane oldies. Now bear with me: this wall (of a small sunroom) is perpendicular to the joists and rafters on this section of roof, and three feet inside is another wall that's sided and insulated like an exterior wall. The inside wall is right where the joists end (nailed to the rafters) and then the rafters continue out to rest on the plate that tops this exterior wall that I'm going to be working on.
Question: is this a load-bearing wall? The framing doesn't clarify much; two doubled 2X4s support a ten-foot 4X4 header all the way across; the interior wall (under the joists) has a single 2X4 between a sliding glass door and a window for that same span (yikes).
SWMBO wants to get rid of the inner wall. Seems like you couldn't safely just let the joists cling to the rafters unsupported, but there isn't much there now except that 2X4 holding up a header... obviously I'm not an engineer or a framer.
Is the wall under the joists or the wall under the end of the rafters usually the load-bearing wall?
