Roof spread

[Beansbaked]

Hi sorry to be asking advice again so soon. Would roof spread cause hairline horizontal and diagonal cracks inside the house? I can’t see any outside but there are definitely new ones inside on the same wall in every upstairs room. This is also the same wall that has a 3 brick step crack at the top of the external wall. The radiators and windows are on the same wall if that is of any importance.

Should I arrange for a structural engineer to come and have a look?

Roof spread would cause masonry damage, yes. Exactly how it would manifest depends on how the structure was built. Step cracking, especially above windows is common in all houses of a certain age.
