I realise the risks with sprinklers and the very high cost of their

enough.

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.
