Hello
I have a question about who is responsible for the costs. I started building my house in September 2016 and successfully completed it in October 2017. The house is single-story. My problem is that I have very large cracks between the walls and ceiling on the upper floor. They are almost 2 cm (0.8 inches) wide. The upper floor does not have a concrete ceiling; it only has drywall. Last summer, I installed OSB boards on the attic floor and screwed them onto the roof beams. According to the construction company, I should only leave space for ventilation at the sides and the gable. I followed these instructions. However, the site manager now tells me that the cracks were caused because the OSB boards expanded and, since they are screwed in, pushed the entire roof structure upward. Fixing this would cost me about 1000 euros.
About a week ago, I removed all the screws from the boards on the attic floor. The site manager said the roof structure would lower again, but so far nothing has happened. The cracks are at the top of every room. I screwed the OSB boards onto the attic floor in July of last year, and the cracks appeared in November.
Is it really possible that the OSB boards could push the entire roof structure upward by almost 2 cm (0.8 inches)? I would be very grateful for any advice, as I don’t really understand this issue.
P.S. If pictures are needed, I can provide them without any problem.
Thanks in advance.
Best regards

... because the OSB boards expanded and, since they are screwed in place, lifted the entire roof frame upwards ...That was the original post, and I based my argument on this statement. If this fact is not correct, then the entire discussion here is just speculation. The question was whether the OSB boards can lift the roof frame, and my clear answer is no.

The question was whether the OSB boards can lift the roof structure, and my clear answer is no. Sorry for the late reply, normally I receive an email notification when someone responds. You are right, that is the main question. I spoke with the site manager again yesterday; he said he would fix it for 700 euros because the OSB boards are to blame... and, as I said, the entire roof structure is being lifted... He and his employees or colleagues are the only ones who see it that way... I will probably need an expert... because two weeks ago he said that if I loosen all the screws above, it will settle back down by itself, but now he says that might not necessarily be the case. I really think this is just guessing what might be going on, it seems that way to me... :-(
