I appear to have a crack on my drywall where it meets the ceiling in my bedroom.
The crack is spreading a bit. I went in the attic and noticed that this rafter beam is cracked and might be causing the ceiling in my room to lift? I'm not 100% sure what's going on here.
But on my other side of the home I'm developing a crack running down my ceiling. On this side of my home I noticed a few truss mending plates have come undone against the rafter.
I'm in Sacramento so we suffered a 5 year severe drought only to be completely drenched this past winter. Now that we're in the middle of Summer were experiencing a ton of heat and our clay soil is cracking all over our yard.
Wondering what's the best approach to repairs at this stage. Do I have foundation issues? Or is it just some wood expansion and shrinkage that's pulling my drywall apart. Do I patch the drywall or call a foundation expert?
This time of year last year I do have some door frames that go out of square leading to minor adjustments and it's been this way for the last two years I have lived here.
More pictures Edit: These are extra pictures, as you can see in the picture 1, ignore the temporary patch job, but the wall and the ceiling have a split and it crossed that piece of drywall, behind the wire for the lamp I put up is a gap about 1/2" wide. You could literally push up on that ceiling piece with your hand and it'll go up.
Picture 2. On the opposite side of the house, in the living room is that straight line crack that is crawling down from the ceiling.
The final picture is just a different part of the house where there are signs of bad drywall patch jobs that were done before we moved in that are starting to show more, like drywall tape that seems to be cracking.
