Plan of NW corner of roof showing location of defects
Two chimney pots have fallen, causing fairly extensive damage to slates; the chimney pots need to be replaced and the roof mended to prevent leaks.
Chimney A missing two chimney pots
Roof damage B caused by falling chimney pots
The haunching around the remaining chimney pots on this stack does not show visible signs of decay, but is built up in several layers which could conceal hidden defects; it will need to be replaced sooner or later.
Remaining haunching on chimney A
The haunching around the chimney pots on these two stacks is badly decayed, and some of the pots are leaning at an angle and move when pushed; I believe it needs to be replaced as a matter of urgency.
