I have just scraped all the moss from our bungalow roof and never want to do that job again.
I am considering fixing copper microbore tubing just below the ridge, along the ridge and down the valley ridges, to prevent moss growth.
My question is will there be sufficient wash-off from this tubing to treat all the tiles from the ridge to the eaves (15 courses) of will there need to be more copper exposed up there?
Thanks for any advice.
