Hello! I have a conservatory on the south-facing aspect of the house (catches most of the rain). I had cavity wall insulation installed a few months ago. I recently note a damp patch on the bedroom wall above the conservatory, and patches running down the conservatory wall which is adjoining the house - I think this this wall is a 'dry-wall' ironically (plasterboard over the house bricks). I've noticed that the height of the damp patch in the internal wall roughly corresponds to the level of the centre support of the conservatory roof. Do you think it could be due a defect of the conservatory roof lead flashing or another problem? Thanks!
