i have used 7mm zinc strip before, it works pretty well but you need to install the strips about every 12th course of slate.

It will work better than the Zinc strips because they have a tendency to "glaze" over after a while and loose their effectiveness.
Would they consider just installing a copper ridge roll instead? That would do the trick without having to attach the strips every so often!
Something like what Olde Mohawk said too. If it embeds itself into the surface of the tile it would last a long time. Good luck!

Matt: I have not heard of using copper for this purpose. However, zinc strips are often spec'd to serve such a role. As an alternative, we have had great success with an anti-microbial solution from Cathedral Stone Products (link below.) "D2" was designed to serve the same purpose, but in masonry restoration applications (ie, stone walls, brickwork, etc.) It is completely safe and highly effective on slate roofs, too.

I have a project where the house has an existing slate roof which has mildew etc on it. My client is requesting that we add copper strips to the roof to the roof after washing it to maintain it's cleanliness. Will this work and what is the proper way to install it? The roof has tile caps mortared on all the ridges. I have received mixed advice on this and if it even works very well. I have also been advised to add strips every 8-10 feet up the roof. I do not want to do this for my client if it will not be beneficial in the long run. Any advise would be greatly appreciated.
