We've just had a leak fixed in the roof above the eaves in an attic room in our 1930s semi. The previous owner was quite elderly and we suspect that leak may have been there for a while.
There's an unpleasant sharp smell in the eaves that I assume is due to damp/mould.
Having a look around I found some patches of a white powdery substance as shown in the photo. These aren't in the areas that had become visibly damp as a result of the leak.
I'm worried this could be mould, but looking at it I'm not 100% so sure. It has a slightly crystalline quality so it might be something that's dissolved and precipitated out. Or it might be mould.
Can anyone familiar with these things identify it?
