    Hi all

    My neighbour and I have erected scaffolding around the Oast House we share in preparation to re-slate the roof which is looking rather worse for wear. Initially we thought we would retain as much of the old slate as possible to reuse and incorporate new slate when necessary, but now we wondering if it might not make a cleaner job to just re-slate it all with new. The new tiles are Spanish, apart from the expense is there any reason to incorporate the old? I have this thing in my head that old is often better than new but the old slate will have multiple holes in them and we're worried about future breakage and slipping, etc no matter how thoroughly we check them. The Oast house is pretty inaccessible and any slipping or loose tile can only be fixed with a scaffolding tower erected.

    Any experience of this would be much appreciated.

    Thanks. P
    Given the stated difficulty if any repairs are needed and the new slates will probably be just enough slightly different dimensionally to annoy the slaters (= higher labour cost) I would put up all new and sell any useable slates as second-hand when the project is over.

    I agree with PIH but before you go down that route check that you are happy with the look of the Spanish slate I find them lacking in character they also break easily I was told by a slater who did my roof so check with your slater about % allowance. Also check if here there is any sort of conservation orders in your area that might mean you need to retain the look of the roof and match the slate.
    We had a house where part of the roof had been re-slated at some point and TBH it didn't look good.

    The traditional slates were random sizes and the old time slaters had sorted them into courses of different sizes, with big ones at the eaves progressing to little ones at the ridge, the perspective effect looked pleasing to the eye.

    The ones on the modern bit of roof were all uniform size and thickness so looked a bit naff when seen next to the trad ones.

    There is no guarantee new slates wont crack, I find Spanish prone to diagonal cracks/fissure lines which drop off

    existing slates if Welsh are likely to be as good if not better - I also like reusing but carefully inspect them especially for frost damage/delamination

    Sort the existing slates to retain what’s good and then ring round the reclaimed slate companies for a good used slate. Spanish are all well and good , but won’t really ever look right. Where is the Oasthouse?

    Thanks for the replies everyone.

    We are based in Surrey Artiglio. What do you mean when you say they won't ever look right, do you mean they won't look right if mixed with the old tiles? Tim, my neighbour who's doing the bulk of the work, doesn't want to mix the two types, its either one or the other.

    A mix will most certainly look odd, but to many new spanish slate often looks “wrong” on an older building. Though once they mellow a bit in 5 plus years the effect is not as obvious.

    Reslate one side with new and reuse the old slates for the other side? You'll never see both side of the house together. A lot of roofs here have clearly been done like that over the years.
