I have just got a quote for a new roof as the existing roof tiles are not
longer made (Belgium made tiles made in 1928 and are of unusual design) I
think they are called Contre. The roofing firm has quoted for a breathable
under felt which does away with the need for venation I have heard of
breathable felts on wood framed houses, but not used on roofs, I take it
that building regulations cover this?

It is the best thing to lay before fitting new tiles MikeS. The membrane is
ideal at keeping the roof space ventilated and also keeps moisture on the
correct side of the roof timbers, so it has become the normal practice when
having this type of roofing replacement done.
