Advice for roof/loft space wanted, have pictures

[Ricmisch]

We moved into a housing association 3 story house 3 years ago in the June. By the September we realised that there was damp coming into the top 2 bedrooms and reported it. They came out and said it was a few tiles on the roof, replaced a few and left. That December my son ended up in hospital with pneumonia. Once we got him well again we fought for months to get a surveyor to sent out. The house was suffering subsidence and so in the May of 2013 some remedial works took place and yet our concerns about the roof which the surveyor did not go into still continued. They continued to say things like its fine etc....December 2013, we told them the roof was still leaking and rain water was pooling on the bedroom walls below and on peeling the wallpaper back it exposed black mould. It was then they said they would re-roof the house. Fast forward to September this year, we realised that water was still coming in. We phoned repairs team again and we got told there is nothing wrong with the loft and that it was bird droppings that was to blame??? After battling for many months again, they sent in a roofer to have a look. He only really popped his head through the loft hatch to be fair and noticed instantly that the chimney stack was perished.
After he left my partner went up and had a good look round and took some pictures. Any feedback and opinions on our roof would be appreciated. Apologies for the long essay.

The perished brickwork of the stack inside the loft will not necessarily be a problem
What looks more likely is that the leadwork around the chimney on the outside is shot and needs re-doing. It's often a problem at the upper side of the stack.
(You appear to have a boarded roof instead of battens, which is quite unusual
and not nowadays regarded as good practice).

Quite right - the Scottish practice is better than just using battens, as long as there are counter-battens to lift the felt. Makes for a stronger roof.

(BTW, OP is in Lancashire, not Lanarkshire, was it mis-read by any chance? )
