Moss on Roof
Hi All
How does this 'copper wire' malarky work to stop moss on a roof? Where do you run the copper wire? -- Dave The Medway Handyman www.medwayhandyman.co.uk 01634 717930 07850 597257 |

Moss on Roof
Runs of copper along roof ridges. Copper salts formed with rain water.
Washes down over moss. Moss either dies or doesn't start growing there. No idea what salt is formed or why moss doesn't like that particular salt. |

Tried it on my last house, I once hung copper stripped from 2.5mm mains wire on the roof ridge in order to reduce moss on my last house. Did reduce on the tiles nearest to the wire but bugger all reduction else where, so not too sure if copper really works. Went a nice shade of green after a while. Easier to let moss build up and brush off. |

No idea what salt is formed or why moss doesn't like that particular salt. Copper Sulphate probably. Rain water was a very weak sulphuric acid due to volcanic dust, and now more significantly, a stronger acid due to industrial pollution. Is this safe to use in a children's playground? Dave |

More surface area, hence more leaching. I have used a solution of a few tablespoons of copper sulphate in a two-gallon sprayer. Spray it on the moss, wait a few weeks for it to turn black, and then get it off. Thomas Prufer |

If you want to use T&E you could run a wire across every 2'. Reason I ask. The client is a pensioner living in a bungalow and the gutters block with moss every few months.

If I completely remove all the moss it will be quite a big job so I'd like it to last as long as possible. Copper flashing lasts 100 years, but is certainly more money than lead. Thin T&E isnt so robust, but if you've got several such wires up there, even if half were to go it should still work.. My roof is slates, each held in place by a copper rivet. THe whole roof apart from the actual copper rivet is covered in moss and lichen. It doesnt work. Unless there is a serious problem with your roof, rain doesnt wash over the copper fixing. NT |

Slates have 3 holes, two about 2/3 way up at the sides which you can nail some copper nails in and one at the bottom in the middle. With that one a large rivet is inverted and slid up between the two slates below and the wire part of the rivet enters the hole from below and its bent down to secure the tile. Look like this: http://www.rylandswire.com/discrivets.htm I dont know what they are talking about with "penultimate row", as each tile has one. |

If it's legal, you could probably do the same job by spraying with weak Copper Sulphate once a year. Magnesium Sulphate (same effect) is what does the job in lawn moss killer, or used to before grandma got elected. Eh? Magnesium sulphate is Epsom Salts, you can buy it at any chemist and probably some supermarkets. Mary R. |

YOu dont know how slates are attached I think ;) There are two nails which are protected from rain and a rivet that isnt. I wonder if youre thinking of asbetos imitation slates. Real slate is attached with a single nail at the top - at least on every slated house round here I've ever seen anyway. Rarely one might find 2 hole fixing, holes side by side at the top. NT |

Round here the slates have just the first two holes you mention. Looking at the web page you quote it's clear that those rivets are intended for top row slates only. Most slates are kept in place partly by the weight of two tiles in the row above. However, for slates in the top row, there is no row above. Hence the idea of clipping the top row slates to the second-to-top row ("penultimate" row) with those rivets. Of course it's possible that in some parts of the country *all* slates are fixed that way, but I've never seen it. -- Mike Barnes |

I ask for 2' by 1' slates at the BM and thats all they have. I'll post some pictures as soon as I can face the ladders, and I'll try a length of copper wire for a while as an experiment to settle the argument. |

Look like this: http://www.rylandswire.com/discrivets.htm I dont know what they are talking about with "penultimate row", as each tile has one. The slates you refer to with three holes, are fibre cement man made slates, known as Eternite or Fasnet. The two upper holes are for the fixing nails and the bottom hole is for the copper rivet. This rivet is there to stop the slate from curling up in hot weather and wind up lift, as these slates are not ridged as natural slate. They are noted for attracting the growth of moss in between the side joints on a low pitched roof. This is caused by the ingress of dirt holding in the side joint. |
