Hi all,

Is there some way of replacing sarking in a roof from the inside and
without removing (or disturbing too much at any rate) the tiles? Or the

Not realistically... To serve any real purpose it needs to be a
continuous membrane under the tile battens.


Wot John said - there is no way to do it that has any meaning.
