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.

Of course - normally I would not bother responding, but since spike
seemed to be posting something that is potentially confusing for someone
else reading later, it seemed wise to comment.

Yup, that can be true.

You may also need to double up rafters either side of a roof (i.e. Velux
style) roof window in some cases)

is, though. (S)he seems to have responded twice to the same original post,

Indeed!

On newish houses, with no original loft, they often use roof trusses.
Useless to make into a room without a complete re-design of the roof space.
