Ask a Tradesman
How would you recognise if a house wall had serious structural damage caused by subsidence and needed underpinning, or if a crack was just a crack and had to be filed and a helibar put in place. I am asking because I have an outside wall that has a crack 4 mm wide on the inside and a bit wider on the outside, that appeared to widen after a new roof was built?
you would need to get a structrural survayor to check. you say youve just had a new roof built this may have added extra weight which could be causing the issues you are having
