Finishing touches on the roof

You can see here that there is a gap, at the back, between the top of the wall and the new roof. This is because the angles on the back and front of the roof were previously different and are now the same.
We filled it in with stones (that have been taken out of the wall to fit the ridge pole of the roof etc) and lime mortar. We needed less than100kg of sand, but the man with the giant tipper truck at the quarry went a bit mad so we got 700kg. We will have plenty of use for the leftovers I am sure.
