That should not happen in a house that's built properly. That said, I don't think it's unusual in lower end production houses.

Most likely, truss uplift.

There are a host of preventive techniques and materials that could have minimized this problem from scratch, but not all builders bother with them.

agreed with worthy, truss uplift. Our builder left our trusses in the lowest part of the yard (wet!) before installing them. The only lifted point is right in the middle of the truss.

So not something to scream over. Your warranty may or may not cover a caulk and repaint.

OP.....is this a track builder? They build as cheap as possible they can get away with,......

Very common, they should have used STC/STCT/DTC Roof Truss Clips

Next thing, you'll be telling us that it's not duck tape, not beem and that a 2x4 is not really 2x4. Jeesh! (Or is that sheesh?)

I love you Virgil!

Good luck, I tried and got nowhere...

Also looks like they used grout at the top between tile and ceiling, where it should have been caulked. I see other places with grout, that should have been caulk too.

Generally where is this project located?

Here is the truss uplift performance guideline of the mandatory warranty programme I am required to meet:

It is not unusual for some drywall cracks and nail pops to occur during the first year after move-in. These can be a consequence of settling or movement in the framing and finishes as they adjust to the conditioned environment inside the home. You may also see seasonal movement in interior trim as it responds to changing relative humidity in summer and winter months.

Where dissimilar materials meet (e.g., a tile backsplash and granite counter, a tile wall and a drywall ceiling, etc.) it is usually better to use an elastic material like caulk than an inflexible material like grout.

Install crown moulding and fasten it only to the ceiling.

Yes.

Sonja:

Please read and comprehend the posts in front of yours. Your pictures seem to show classic truss uplift.

Can this be fixed please?

Short of major redoing of the framing, best to disguise it as mentioned above. And be sure of adequate attic ventilation and insulation.

"Repairing existing truss uplift damage focuses on concealing the movement cosmetically without restricting the truss, which is crucial to avoid transferring structural stress to the interior walls. A simple application of rigid joint compound or spackle over the gap will typically fail, cracking again during the next seasonal uplift. For small, hairline cracks, a flexible, paintable acrylic caulk can be used to fill the seam.

The most common cosmetic solution involves installing crown molding or similar trim, such as quarter-round, around the ceiling perimeter. The molding must be fastened exclusively to the wall, not the ceiling or the truss. As the ceiling lifts, the molding slides up the wall, concealing the gap behind the trim profile.

If trim is installed this way, it is helpful to paint the wall surface directly behind the top edge of the molding before installation. This prevents an unpainted wall stripe from being exposed when the truss reaches peak uplift and the molding slides down. Avoid re-securing the separated ceiling drywall closer to the wall, as this re-establishes the rigid connection to the moving truss, guaranteeing the problem will return."
