Thinking about getting the roof overhauled using the same tiles, and
then getting http://www.warmroof.co.uk to bond it all together with
foam, to cut down on further slippages and add some insulation. We can't
have much traditional insulation over the ceiling, the ceiling joists
don't allow much depth and we still want to use the loft space for
storage.


Don't even think about it. It's a bodge of the first order and you'll
regret it.


I can't see anything wrong with bonding slates together from below but
that wouldn't involve covering the whole surface with foam. A couple of
lines of foam between each joist would probably be sufficient, and
that's an easy d-i-y job. It would make the slates unuseable in the
event of a refit though
