in buildings the roof is very important if it is tiles there is close

the building has been compromised it could be a big cost and it could
land you in some hot water with your local council

Why would the rafters require strengthening anyway? They were designed
to carry the load of tiles they have, you you have presumably not added
more.

With loft conversions, the primary thing that needs strengthening is the
floor of the loft, not the roof.

I presume you noticed the original posting date :-)

ISTR that if you replace tiles with a different type then the roof loading
can be increased. Concrete tiles? However no suggestion this happened.

I'm not sure how clued up the person posting tales of doom 7 years late
is, though. (S)he seems to have responded twice to the same original post,
as well.

Ah, well, summer holidays.
