We bought a house recently, we focus on almost everything. Do the all searches and surveys. The one thing is that we didn’t check is the roof.

So I went there now for a recon and I think it is not so bad, but what bring my attention is a white thing on some roof beams.

I notice also that on the both sides an old beam has been support by additional beam which looks quite new. Should that new beam be painted by something to protect it ? Because it is not.

Please have look for more pictures of the white thing

Hi Obelus

That looks like the timbers are, or have been wet, and have started to rot.
Although the new beam would indicate repairs may have been made, I would suggest that the roof be examined by an expert without delay.

it looks like dry rot to me, But even if its not they will need replacing,

Make sure there is adequate ventilation in your roof space as condensation can be a real problem for roof timbers - find more advice on that here https://www.diydoctor.org.uk/projects/damp-and-mould.htm
