I did a job on a one year old townhome yesterday. This was a new home warranty job.
The unit is in the center of a block of 5 units.
Cracks have developed at the joints between the partition walls and the ceiling at several locations. The owner tells me the cracks were there when they did the PDI and repairs were made. The cracks have re-appeared in the same places as before- they are bigger now.
I checked the attic and noted the Trusses are parallel with the side walls of the unit and perpendicular to the areas where the cracks are.
I suspect Truss uplift to be the cause. Am I in the right ball park or out in left field? What is the fix, if I am right?
