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.


There must be tons of molten, now solidified lead piled up
somewhere, imposing a nasty non-distributed load up on
that 'roof' somewhere. It can't have all poured down to
terra-colder.


Course if that'd had been the UK the Pikey's would that had it away over
the weekend ;!..

As is their won't..
