We have new cracks in our ceiling coming out from where the chimney is in the bedroom, there are also hairline cracks in the top of the wall near to this. We did have a loose tile on the roof which was fixed November time last year, so possibly could of been that? I am concerned that there is movement in the chimney? two of the brackets which were located on the corners of the chimney have blown off of the roof. I want to decorate the bedroom, but need to address the ceiling/chimney first any help would be appreciated please. Thank you
