After a mammoth late night session last night (I promise to go to bed earlier tonight!), the roof was finished. It needed a few bits re staining this afternoon but was soon looking like this;

And then before I could get too attached to it;

Actually it took quite a long time carefully damage it as did not want to destroy it completely and then a few dabs of glue to secure some of the flapy bits. Still much work to do in getting the weathering and the brick colour right as well as some detail parts and general junk but much of this will need putting in when the building is bedded down on the layout to make it blend in properly. One major area needs a lot of work - roofing tiles. On my reference picture there are none at all on the roof which can only mean that they are all dumped in side! I have a plan for these which I shall reveal when I know it works.
