Imagine a pipe on the roof to act as a big sprinkler - early
deployment would have killed the fire. Cost - some pipes.


The roof is deigned to be waterproof, so you would need a system that
worked inside the roof space to do any good before the fire broke
through the lead cladding. That would have to be rather more
complicated than just a pipe on the roof.

Better IMO to rebuilding it on a metal framework, making inherently
non-flammable. The roof is relatively modern, so nothing would really
be lost by making it of modern materials, so long as it looked the
same from the outside.
