Eric Posted April 1, 2021 Share Posted April 1, 2021 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 Link to comment Share on other sites More sharing options...
PeterW Posted April 1, 2021 Share Posted April 1, 2021 Do you mean copper restraints on the bottom edges ..? What’s the slate size and pitch of the roof ..?? Link to comment Share on other sites More sharing options...
Eric Posted April 1, 2021 Author Share Posted April 1, 2021 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. Link to comment Share on other sites More sharing options...
tonyshouse Posted April 1, 2021 Share Posted April 1, 2021 Moss is a problem on all roofs, not sure if copper strip will do it evenly as water doesn’t run very evenly Link to comment Share on other sites More sharing options...
epsilonGreedy Posted April 1, 2021 Share Posted April 1, 2021 (edited) 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. Edited April 1, 2021 by epsilonGreedy Link to comment Share on other sites More sharing options...
