Bernd:
Darren,

That roof is looking pretty good. A couple of questions. Appearently no subroofing material is used, just purlins (the small pieces of wood run running parallel with the slate) to nail the slate to? And does the slate have holes in it already to nail through?

It's facinating to see how in different countries the build techniques are so much different.

Bernd

Darren:
Hi Bernd,

No purlings in this roof, what we have here are trusses, though I made them up myself. The down bits we call rafters and the cross pieces we call battens.

The rafters are 2x4's and the rafters are 2x1's. The sheet is a breathable waterproof membrane.

The proper way to slate a roof is to sheet the whole roof in ply, then the water proof membrane, battens and finally the slates themselves. but in all the years I have crawled in roof spaces as an electrician I have never once seen the ply sheets...

Do you use ply over there?

Most slates come ready holed, but I'm tight so bought mine without to save on cost. 700 slates would have cost me £90 to have holed. I did it in 3hrs so that's £30 an hour.
I'd do it all day for £30 an hr...!!

You just bang a 4" nail through with a hammer to make the holes. I made a wooden frame/jig and did four slates at a time. You could hole them as you put them up with the copper nails but it's easier if you hole them on the ground first.

Darren:
BTW, Here I could have used metal sheets, polyroof, or just about anything for a garage or shed.

But in this area of the UK all house roofs have to have slate, a ruling to help the local industry as it's a slate mining area, nothing else is allowed. Slate is produced here but everyone, inc me, uses Spanish slate..

Go figure....

John Stevenson:
I like slates, they are permanent.



Shot of the back of our house, the main roof was put up in 1901, the kitchen extension is done with new slates and was done in 2004 and there is hardly any difference.

JS.

Darren:
I'm still trying to work out why you needed an extension .....  :lol:

That house is huge.... :clap:

Yes, I like slates, next door has just had it's roof re done, last time was nearly 200yrs ago apparently.
And they reused the old slates, nothing wrong with them. Just some of the timbers had gone, but not all of them !!

I chose slate cos I'm getting older, 10-15yrs other products would need attention and I would be way past getting up there again.
By the time this roof needs looking at I'll be long gone  :ddb:
