roof moss

[LBerry]

Is there any treatment for heavy moss on domestic roof other than the rather expensive treatment offered by the likes of Aquashield? I would prefer a suggestion that someone has personally used successfully, as opposed to links to other sites. Many thanks.

The best way is to go up a ladder with a scraper & get it off as I did but I do live in a bungalow,
If you dont get it off you will end up with your roof leeking.
Good Luck.

Scraping it off is the first step. That's what our local council do on their housing.
The old remedy to stop it growing was to string a bare copper wire between the chimney heads exactly over the middle of the ridge tiles. Minute amounts of copper sulphate would form on the wire when it rained. This would be be washed down the roof, and kill off any moss trying to grow there. (You'll see no moss below a copper overflow pipe that is poking up through a roof).
