    has anyone used industrial/agricultural cladding on a domestic roof? Finalising a design at the moment and I am very taken by this house (below). I love how light the roof looks and I think it would look great in rural Ireland. Also there is no guttering - anyone tried that?

    I did a round half barrel roof sheeted with corrugated metal painted with red oxide. It was really only for show, we got timber round roof trusses manufactured we sheeted them and they were covered in torch on felt, then purlin were screwed to the roof and the cladding foxed over it. It looked well afterwards but I would only use it as a feature not a roof. You need a real roof underneath and fit this afterwards for show. If you used it as the roof itself you'd have to deal with condensation on the sheets and the like. Also this roof was seriously expensive!!

    Yes, in the middle of it now. A 32mm corrugated roof to imitate a traditional barn. Built up warm roof underneath. Passive build.

    Cant see the link but I guess hidden gutters are what's used...lot more design and pre thought needed for this.

    Ode To The Motorist

    “And my existence, while grotesque and incomprehensible to you, generates funds to the exchequer. You don't want to acknowledge that as truth because, deep down in places you don't talk about at the Green Party, you want me on that road, you need me on that road. We use words like freedom, enjoyment, sport and community. We use these words as the backbone of a life spent instilling those values in our families and loved ones. You use them as a punch line. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the tax revenue and the very freedom to spend it that I provide, and then questions the manner in which I provide it. I would rather you just said "thank you" and went on your way. Otherwise I suggest you pick up a bus pass and get the ********* ********* off the road”

    @Miller_63 Very interesting. Have you any concerns? Did you see it in operation before you went for it? Would love to see some pics.

    No pictures yet as material hasn't arrived yet, in fact im on the hunt for an experienced installer to help and guide me on the physical fitting of it. Im scared :-) I should be taking delivery late next week.

    With regards to that picture, im unsure if the colour would get through planning. I think basically with corrugated you have two colour arguments if you trying to imitate older structures in Ireland. Dark Grey and Red. I had to submit a sample to satisfy planners.

    I am working on an extension and have found a multitude of examples of houses/extensions that use corrugated sheet as roofing and/or wall cladding. For materials check out Euroclad (Naas). I'm inspired by a really low-cost example :http://www.irishvernacular.com/
    That one used Onduline sheeting, some users in other countries have reported problems with it.

    I have seen corrugated sheet roofing used over straw thatch in old houses, the thatch still pretty much intact and not rotted after eighty years. Contact Tegral in Athy, they may be able to help source the colour sheeting you require, also Kildare county council produced a book on traditional rural buildings which could be worth a look

    That would be our roof, guess the original CGI roof went on in the 60's and I had to replace one section recently because of rust due to some sheets being levered off when an extension was bodged on in the 70's.

    Thatch is a bit dried out under the tin but not rotten at all. Main thing to remember is NOT to use an angle grinder anywhere near it in case you set it alight.

    Superdaddy,

    When you say cost effective - what's a ballpark figure per m2 or per length? Have you have to adapt your roof build up at all? Extra starking boards or did you purchase as a SIP's type panel as shown on the quick google I did here:

    http://www.euroclad.com/roof-systems/vieo.aspx

    Those U values don't look great - well 0.15 may be ok.

    Ever seen guttering on a thatched cottage?

    What you will often find is a drain thats directly under the drip line (or near to it) running around the house. With a new build you could put modern drains around the drip line and cover with gravel.

    It's ready for the Vieo sheeting, should be here next week. Gutter, facia and soffit are made from the same material and go on first.

    Galvanized steel obviously has a limited lifespan - think of all those rusty haysheds around the country.
    Is aluminium corrugated cladding too expensive to consider ?

    And just how old do you think most of those rusty haysheds are?

    Our CGI roof is over 50 years old and has very little maintenance.

    They outlast most people reading this, I wouldn't be too worried about it.

    Over half the cladding done on the back of the house, north side, will add more photos when done. Really happy with it so far, looks great, I love the gutter and soffit. Barges and flashings yet to go on.

    Yup! That's where the standing seam roof originated from. Modern materials to imitate an original form.

    @Superdaddy I am talking to Euroclad at the moment and they are quoting VieoZinc @ €28/m2
    Vieo HPS coated steel @ €23/m2. Is this what you are using?

    Great job, looks good. How is this roof cost wise as apposed to a standard slate roof? I have an old farm yard stone shed im planning to renovate, starting to get quotes this coming week.

    Also what way are you doing insulation? Are you getting insulated cladding or insulating it seperate? Or both?
