I've got some solar water vacuum heating tubes to experiment with,
but how to attach them to my slate roof?

I'm thinking of using standard scaffold bars and clips,
so that I can easily adjust the height and angles.

But how to attach the scaffold to the wooden roof beams/rafters/joists?

And how to get the scaffold tube up through the slate waterproofly?

Are there fittings I can buy, what are they called, and whereform?

Or how else can I do it?

I've just done the solar panel thing.. I bought a kit of bits off
Navitron though. The frame that holds the tubes and manifold is held
onto the roof via four thin stainless steel strips, (2 at the top, 2 at
the bottom) pushed up between 2 tiles then wrapped round a batton behind
the slates. (No felt in my roof) Seems to hold it very securely in-place.

Steel scaffolding is really heavy... Not sure I'd use that myself.

Have a look on the navitron site for piccies, forums, etc.
