A bit more progress on the roof.
The first 2 bay roof is installed and this part of the shed is becomeing quite ridgid. I have started fitting both roof and wall cappings. It look like I am going to see if Wills will sell me some extra roof sprues as I will need some more roof capping and if I use them the smoke jacks. I will also need 2 more packs of slate roofing. Still quite pleased with progress so far.
