Standing seam vs Slate for pitched roof

[Mrog]

We are finalising the design for a 1.5 storey oak-frame build in a Herefordshire. Main roof will be clad in slate (probably Spanish). The design features a single storey, pitched roof area of around 20m2 that will form a snug. We are considering using a standing seam roof (zinc as a preference) for just the snug roof, if it doesn’t increase costs significantly.

 

Has anyone recent experience of pricing fitted zinc standing seam over decent quality slate? As a lighter material, I am also interested if you saved anything on the roof structure by using standing seam?

Judging (only) by a few posts on here re difficulties with quality on standing seam roofs I wonder if you might have things against you - not least a roofer wanting to 'get out of bed' for 20m2, when there are full houses to be done. Or I may be too pessimistic - 20m2 may be just enough to fill that small gap left after the last job...

When I was pricing up, zinc was an option soon dismissed, when I got the prices. In the end I did a Sarnafil pvc roof with decor profiles at 450mm centres. But we did about 200m².

Standing seam is great for large areas as the middle is easy. The edges are difficult, so it isn't great for small areas.

 

Standing seam is industrial cladding pretending to be lead. I don't mind seeing screws and saving 1/3 or more.

I wouldn’t bother swapping materials, you will need two different contractors, trying to find one is hard enough. 
stick to slate.

Great points both. I was hoping that the work would be enough to be of interest but it may be well be "too much edge and not enough middle".

At this point I was just testing if I could discount the option through on a cost basis. But you are well ahead of me in thinking of sourcing the skills, even if the work is affordable!
