Reply to comment by [deleted] in How to fix truss lift cracks? by flaccid_porcupine

Thank you for the reply! My understanding is this should/could have been addressed at the construction phase, like you say. My builder is out of the question for any resolution, as they are getting hit with some lawsuits by us and neighbours (surprise, surprise...).

Do you think it would be possible to help address this by getting up into the attic and screwing the trusses down to the top of the wall? I'm unsure, as it all wants to move and will want to continue to do so... it might not appreciate being restrained and that could manifest something worse

The 1/4" gap above our tiled shower wall is a real eyesore that even crown moulding won't fix (shower area = wet)

I have truss lift at my home as well. From what I've researched, nailing or screwing the trusses to the walls runs the risk of the entire wall being pulled up from the bottom plate or breaking/splitting the wood.

A couple of years ago, I had enough of it, went into the attic and located the nails were the drywall was fastened to the trusses in relation to the corners of rooms that had broken drywall seams. I used an oscillating tool to cut only those perimeter nails where the lift was happening. My ceiling drywall was installed before the walls so there no worry of it falling or sagging.

I'm a DIY'er for sure, so don't take this as gospel for your home, but thus far I've had no issues since.

I've heard about cutting those screws to "float" the drywall. That's something we've considered doing for the worst locations.
