    Hi All,
    I've just had my gable end chimney stack removed from my 1870's house
    by a roofing firm. I made a few enquiries beforehand and was told the
    same method of doing it by everybody I spoke to, essentially remove
    stack brick by brick to below (slate) roof level, put battens across
    gap left by chimney, attach new slates to the battens then attach
    ridge tiles and done. And thats exactly what happened and everything
    seems fine and all the new slates line up and everything looks
    perfect. Only problem is I am a born worrier, and whats bothering me
    is the weight of two ridge tiles on the battens which are presumably
    only designed to take the weight of the slates. All the other ridge
    tiles are supported by a bloody great ridge beam but that ended by the
    chimney stack so as its gone there is a gap about 26 inches where the
    chimney used to be where two ridge tiles are only supported by the
    slates sitting on the, what look like, small battens. I have this
    vision of the battens giving out and the two ridge tiles ended up in
    the loft.
    I do realise the ridge tiles are pointed to the slates and to the
    ridge tiles besides them and theres only 2 of them like this and so I
    am probably typing this for nothing but could I please just hear that
    from others to put my mind at rest or alternatively do I need to sure
    anything up?
    Thanks for any advice given,
    Steve.

    And the 18 - 24 inch thick brickwork below the battens...IE the remainder of
    the chimney.

    The rest of the roof might cave in at any moment, but this patch above the
    old chimney will still be there...and even if the chimney has been removed
    completely, the outer wall must still go up to the underside of the slates -
    the wall alone will be at least 9 inches.


    Also, it wouldn't matter if there was no brickwork supporting any of it -
    the battens aren't designed for roof tiles alone, how do you think they are
    laid? - by fourteen stone roofers walking across them.
