Fixing the Roof

The roofers who started some maintenance work on the roof to the rear of the house yesterday finished the job this morning, initially to my complete satisfaction, and left, after which I spotted, only visible from the end of the garden, a gap in the tiles and a brush-head in the gutter; fortunately the gaffer was calling later with the bill so he was able to shin up the ladder, put the offending tile back in place, and retrieve his brush before making off with the money.
