Material compatibility

[eandg]

We are considering wrapping zinc (or, more likely, a cheaper metal) around the roof and gable walls of our build with cedar shingles at the front and rear. I've read that cedar is acidic and can corrode metal which makes me question its suitability. It wouldn't be fixed to the metal but would but against it in places, and with aluminium clad windows. 

 

Thoughts?

It's the run off from one material to the other where you can end up with issues - I'm sure zinc and cedar aren't a good combination but it makes a difference on which way around the run off is going, vmzinc have a little bit of technical info https://www.vmzinc-us.com/zinc-basics/compatibilities.html but I've seen something much more detailed recently (just can't put my finger on where!)

Great, thanks - I'll have a look after work!
