Corrugated roof material - recommendations?

[Great_scot_selfbuild]

Hi,

 

We’re looking to have a black corrugated roof (example photo attached) and would appreciate advice on:

 

Recommended products & suppliers

What is the layup? It will be going on top of insulated modular timber panels that have been manufactured off-site and are blown-filled with warmcel insulation once installed on site. Interested in what the various layers will be on top of this.

 

TIA

Assume min 60 yr life required, so not corrugated bitumen board, in my experience (although poorly-supported bitumen boards 'go' a lot quicker). I took off some (?pre WW2?) corrugated in about 2015 and yes, it was 'chewy' at the edges, but (a) so much thicker than modern, (b) still with most of its galvanising on and (c) solid as a rock at all but the edges. 

 

Self-coloured, of course. Epoxy if you can.

 

Layers I could guess, but I'd be guessing, so I will leave that to others. Battens and counter-battens will be involved, I suspect.

Tried searching for sinusoidal cladding? There are plenty of options.

We've got a black sinusoidal roof, bought the panels from here: https://www.panelsandprofiles.co.uk/  they might be able to advise on build up too, also some info on the Cladco website (though they seemed the most expensive IIRC). You'll also need to get flashings (eg for the ridge) and foam fillers

We have black corrugated roofs and walls to the 2 storey section of the house - images here -> https://lhc.net/projects/ashcroft-creating-a-low-energy-family-home/

 

Our son was the architect and specced the tin. From memory it has at least a 45 year guarantee - I think it was Firth steels. We used a company in Leominster to do the actual supply - Thomas Panels and Profiles.  They suggested a contractor to do the actual build but we sacked him off half way through and our main contractor finished things off. fastenings were EJOT.

 

I can get more detail if you need it.

We found it hard to find examples to go and see in real life - there's probably more around now. You're a long way away in Surrey but you're always welcome if you are up our way to have a look at ours.
