Hi - I've been trying to determine the root cause of a ceiling crack for a customer. When the customer first called, they said there had been a crack in their vaulted ceiling, at the peak, almost since it was built 20 yrs ago. There were some other cracks on interior walls where the ceiling met the walls as well.
I went in and repaired it, assuming that using StraitFlex would take care of the peak, and that over the years the remainder of the cracks were due to settling, etc., because there were some issues with settling in the basement. I researched truss uplift, but was not sold that this was it.
Well, the work has been completed for 3 months, and now there is a crack on the ceiling that runs parellel to the peak, but not along the tape seam (it is about an inch below the edge of the tape). It appears that the sheetrock itself 'cracked' due to the tension near the interior wall. There are some hairline cracks that have appeared on the tape joint where the vaulted ceiling meets the interior wall. I haven't been in the attic to determine exactly how the addition was framed, but that I think should be my next move. I will verify framing if possible, what type of inso, etc. so we know exactly how the room was built before proceeding.
There are no cracks along the exterior walls. My assumption is that it is stick framed, but it could be a scissor truss. I can't figure out why the sheetrock would crack as it did. We have had some extremely hot days in the last month, and with the vault, I would think that humidity and the heat are wreaking havoc on the framing. Cold interior and extremely hot exterior - is it possible that even stick framed , ie 2x10 or 2x12, would see similar expansion issues as in truss uplift?
Anyone else seen this? I've researched truss uplift, but don't know for sure if that is what we are seeing.
Thanks in advance for any advice.
