    I have a Victorian house with a big roof which is in not brilliant condition. Some of the tiles have deteriorated on the edges and a few are broken. Because there is not any underfelt I can access the roof from inside the loft space.

    I intend to inspect the roof with binoculars from accross the road then go inside my loft and replace any damaged rosemary tiles.

    Some of the tiles on the inside have had mortar thrown into the joints but most of this has dropped off (about 115 years old).

    Four questions:
    1.Is this realistic as a project - I am a pensioner and cannot afford a new roof. However, I do have all the time in the world, so can easily spend a year doing it slowly.
    2. How tight do the tiles need to be pressed next to each other. Do I allow a small gap of say 3mm or do I press them hard so that they touch each other?
    3. At the eaves it seems I need to cement them. What cement/sand mix and how far back - one tile width? (I can get access to the eaves via some opening skylights.
    4.Nailing. How often should I nail? What nails (aluminium, copper etc) and how long. (I can nail by removing two rows of tiles and can get my hammer through - I have tried it.

    Afterwards I am going to put silver foil bubble wrap across the rafters as per another post.

    Thanks for any help

    Its not a realistic project! especially with rosemary tiles.

    At that age chances are the tiles will be delamenating(the surface glaze starts blowing off) and the underside of the tiles start to degrade.

    When you start removing the worn tiles the others around them will break.

    If this is for aesthetics and the roof is otherwise doing its job i would leave well alone.

    Not to mention hanging out windows to point verges.

    Yes you are right about some of them delaminating. But I have replaced some in the past and I didn't notice any problems with the adjacent tiles.

    I had a good look this morning and it seems like I need to replace about 200 tiles.

    Is it likely that I will break the adjacent tiles? If I get a roofer in to do the job won't he effectively do the same job but from the outside?? Or am I wrong about that?

    Anyway coming back to the idea. Do the tiles need to be pressed up tight against each other ?

    I think you are right about hanging out of the skylight being too dangerous. Cannot imagine why I thought that was at all feasible :)

    How often do they need nailing?

    Thanks again

    Repairing from the roof is likely to break as many as is repaired.

    Nailing patterns will depend on exposure....Banff i would nail every tile.

    Butt them tight to each other.

    Thats the problem, the tiles will be very brittle and no matter how much care is taken the percentage of breakages will be high no matter who does the job.

    Thanks all.
    There are some parts of my roof which are not visible from the road and I am wondering about these 'double tiles' for speed and other properties. Anyone used them out of interest? Any comments on them? I know nothing at all about them but was CONSIDERING getting a roofer to do part of my roof using these.
    Obviously subject to cost and suitability and so on.

    Also, does anyone know if they look convincingly like rosemarys?

    All the best

    I know it's been a while since your this thread was started but I noticed it was never solved and I found it via google.

    If you haven't already resolved the issue, the the only options you can do from the inside are:

    1. use roof glue to fix the tiles together- this will help prevent them being flown off storms and extend the life.
    2. use roofing spray foam under the tiles. Loads of companies do this or you could do it yourself. This will fix the tiles together to prevent them being blown off, extending the life, & also add insulation. NB. It's frowned upon by people who make money from installing roofs because they want to make money, but the simple fact is if you can't afford to hire someone to replace the roof then it's a lot better than nothing. It'll make it harder for a roofer to replace individual tiles as they're glued together by the foam (he'd have to replace all the tiles with new unless you find a very skilled guy), but if your roof is at the end of its life, replacing a few tiles isn't an option anyway.

    I've done a lot of research online regarding the above options. Option 2 has a wide variety of mixed reactions- people who swear by it and others who say it's the worst thing to do. However, the latter can't imagine some people don't have enough money to replace the entire roof, or roofs that aren't at the end of their life. They don't appreciate people who are in immediate need of extending their roof life and don't have the funds to replace it. From my personal experience almost all tradesmen assume you just want to save money as opposed to literally not having the money- which says more about their finances than yours!

    Hope this helps & indeed helps anyone else searching for the same thing.
