    Out of curiosity, will a grinder with a slitting disc in cut slate roof tiles OK?

    Some of ours (and neighbours) overhang the gutter too far and we want to trim them a little.

    I have no idea what a slitting disc is, but yes they can be cut in-situ with a masonry or diamond bladed angle grinder or Stihl.

    Be careful of wander, snatch and the angle you hold the cutter. It will behave better whilst you are only cutting one layer but as soon as there are two layers or more it will snatch and the tiles may try and kick.

    OK cheers.

    As slitting disc is one thats used to cut metal, they are quite thin. (I have several).
    If we do this Ill get a diamond bladed one.

    Diamond disc is what you want (used for cutting tiles as well). If you're cutting real slate then fine, if they're fibre cement then beware- the factory edges are sealed, hand cut edges shouldn't be exposed to weathering (and at the foot of the roof into the gutter that is a lot of weathering).

    If it was me I'd be spacing the gutter off the bargeboard a bit - far less destructive (but also more difficult, specially if its the original cast iron stuff)

    Yes. It was a yes to your initial question.

    Nobody does what you are purposing so why not post a few pictures and then you can get some advice about a more conventional approach! without the need for an angle grinder of ladders.

    Cant do that until going up there.. so I may do eventually.
    I just wanted to be armed with some knowledge when discussing it with the neighbour.

    How old is the property? it could be a case that the unders are slipping out.

    built in 1855, mine was re roofed in 2007. next door longer than that.
    Can't tell the extent or accuracy of this until I get up there which won't be for a while.
