Copper strip required for Cambrian slate?

[Eric]

Hello,

 

Just wondering on your thoughts regarding the use of copper strip for Cambrian slate, which is artificial/reclaimed slate.

Is it worth doing anyway or is it not required for slate?

 

Thanks

Do you mean copper restraints on the bottom edges ..? What’s the slate size and pitch of the roof ..??

Hi @PeterW

 

Sorry I should have pointed out that I was relating to the copper strip used under the ridge to stop the growth of moss etc.

I’m not sure if it is a problem on slates or more specific to tiles etc.

Moss is a problem on all roofs, not sure if copper strip will do it evenly as water doesn’t run very evenly

One expensive option for anti foul paint on a yacht's bottom is a paint comprised of epoxy + plus a copper powder mixed in just before painting. The concept has a so-so reputation and success depends on sanding the anti foul paint once a season to expose fresh copper. I only mention this to highlight that the toxic effect of copper declines as it oxidizes.
