If in doubt best check with a builder for safety. Some pictures would be great!</p> Hi Paul best to use an insulated flu pipe- from the stove up it can be single skin but should be insulated as it passes through the roof, which also helps the stove burn more efficiently.

I am about to put the green roof on(similiar to the way you did yours using builder and silage cover). I want to put a flue up threw the roof? I was thinking of using a couple of sheets of galvanised steel with the flue threw it with led around. Do you think this would work. I dont want the plastic to melt, or any insulation to go on fire. I see you put your flue out the side. I am building my walls with straw, plus I already have a straight flue sourced. Thanks again Graham, will I send u pictures so far?PaulC</p> Graham, Paul here again. I have my structure up and braced.

Any pictures would be appreciated. Here is the only article I can find about skylight in reciprocal roof: http://small-scale.net/yearofmud/2009/07/30/making-a-custom-tractor-tire-skylight/</p> <p>Thanks!!</p> Hey Graham, please write what did you use to cover the hole on the top of the roof(the inner circle).

Some people have used raw wool instead, usually they have added borax to it to deter pests. This could be done by spraying it once it is placed in situ in the walls. I chanced the washed wool without borax- the debate as to which is better continues... On the roof I used 2 layers of builders plastic, and then a couple of layers of pit sileage cover which comes big enough to cover the whole roof several times in one piece with no joins. On a similar roof we used radon barrier plastic, but it required joining with adhesive and tape. I didnt bother with drainage, but there is a down-pipe at the lowest corner. No plans for a cordwood course at present Im afraid.</p> The wool was purchased from the UK washed. Some people have used raw wool instead, usually they have added borax to it to deter pests.

Could I ask you another qeustion please? How did you wash all that sheeps wool for insulation? Washing machine or do you buy it washed? Your green roof, did you just use several layers of that cheap builders plastic that comes in roll, then rotted hay? what a bout gravel for drainage? Appreciate it again, I am getting there. Oh and do you planon doing a cordwood coarse soon?Paul</p> Graham, very well explained article. Could I ask you another qeustion please? How did you wash all that sheeps wool for insulation?

This could happen I suppose if there was a persistent leak - but for it to be that bad the building would have had t have been in a state of severe neglect for a long period i think! True enough, it might only take one pole to go for the whole roof to cave in but it would be unlikely to happen all of a sudden- I think there would be a chance to try a repair before complete collapse- hopefully the same for society as a whole! :) Im not sure what would happen</p> Hi Nick I think I understand your point but a single pole failing would be extremely unlikely- there is no reason to suppose one would fail unless it became completely rotten.

is each main pole of your reciprocal roof fixed into a common element such as a steel hoop at ther top? I wonder what happens if a single main pole fails for any reason. Much like a lattice truss, the reciprocal roof without a tensile common top element does a fine job of spreading the load but relies on every pole being perfect. You’ll notice that most buildings utilising conical roofs without a central support are designed with each pole fixed into a tensile ring so that a number of poles could fail without the roof coming down.

I’m a bit of a worrier and I imagine the weight of the whole roof relying on the integrity of one pole: which one, of course, would only be known in the case of a failure – the load only being spread elegantly between the poles if they are all in pefect condition.

By the way, I’m not a structural engineer but my family had a structural engineering practice for many years and the phrase in the design office was “never trust a truss on its own”.

Otherwise, a beautifully simple and elegant building!

Best wishes

Nick

Just wanted to say how much I liked this post. Our family is looking at more sustainable green living. Step by step we are trying to adopt a more natural lifestyle. I think that what you have done here is wonderful. Thanks for sharing.</p> Found your blog by chance today. Just wanted to say how much I liked this post.

I like the careful framing you did for the opening and your choice of plastic for the roof liner. Are you still without leaks? Any suggestions you'd offer to someone also doing a reciprocal roof with timber? Thanks for any suggestions!</p> Hi G, I’m loving your roof!
