    hi all new to this, we are doing our roof and the timbers are fine house is 60 years old never had felt and has some dodgy looking slates, my question is on removing these light slates could we put on concrete tiles or would the old roof be fit to take the weight? would be very grateful if anyoneone who has done such a job or anyone who knows about this sort of thing could get back to me :)

    All depends on:
    The size of the rafters,
    The size of the Joists/Collars,
    Connection of the rafters to the Joists/Collars,
    Connection of the rafters to the wall/wall plate,
    Span of the roof,
    Pitch of the roof,
    Is there a purlin present, if so, what size is it,
    Is the Ridge acting as a support, if so, what size is it,
    Are all the nailed connections in good repair, and were they all carried out properly.

    Basically get an experienced AT/Engineer to look at it for you.
    My feeling is that the existing timbers are 'life stressed' to their previous loading and replacing slate for tiling is adding weight about 8 fold on the roof. I wouldn't do it, too much to go wrong.

    or it could just be a case of beefing up the carcass you have, get someone to check it on site.
