The roof space is effectively three roof spaces – one for each of the cottages. Two end walls with a wooden “A” frame in between the two. The “A” frames look in reasonable condition. I have had a look in the roof space in one of the other cottages and the construction is the same.
The roof is constructed using traditional stone slates (called Yorkshire Greys). These have a single hole in the top and a wooden peg that us used to hook them over wooden battens.
I have no idea what this tells us about the date of the construction. The one thing that strikes me as odd is that the end walls seem to have been painted. Not quite sure why anyone would want to want inside the roof space.
