If a terraced house had a slate roof with no underfelt, would this be

Or is having no underfelt on a roof not a major problem, and
something
which can be lived with i.e. not usually considered an "urgent"
problem.


Our roof (1930s) isn't felted. It's not a problem except where there
are
gaps in the slates. When we replace the roof (probably this year) we
will felt it.
Hopefully with a breathable membrane and not 'felt' (old-fashioned?)

Our new (to us, built 1880) house doesn't have felt, and others in the same
street have had problems after felting theirs due to lack of ventilation to
the roof members. one thing about not having felt is there's plenty of space
for air to get in and dry things out. If the house was built without one,
just keep an eye out for missing tiles in high winds. If it originally had
one though, I'd be inclined to get it re-felted pretty quickly.
