cheap anti-foam roof and roofs: copper




by Christophe » 04/09/07, 16:04

We had talked about it recently but "drowned" in another subject, so I created this new subject to talk about this eco-friendly anti-foam trick which consists in putting a length of copper on the roof to prevent the development of mosses on the roof.

Some questions remain for those who have installed such a system (remember who had talked about it):

1) what is the efficiency in terms of the system's length of action?
2) what is the minimum dimensioning of the copper part (relative to the dimensions of the roof)
3) life of a piece of copper depending on its thickness?

Hello

1.5mm² copper wire is sufficient; placed parallel to the made every meter.

lifetime 10 to 15 years.

CAUTION: never use on a slate roof with galva hooks or galvanized rim (stainless steel or pvc imperative); otherwise slate that fly and goutière with guaranteed hole.

Ok and thanks for the precision, the field of action is therefore 1m for 1,5mm2.

Shit is our case .... but there are already holes in the goutières : Mrgreen:

copper was already known by the Egyptians under Ramses II and even before.
It is a powerful anti bacterial, even at homeopathic dose.

Of course, beware of electrolytic couples

I know a person who practices this "defoaming" by the copper wire and this there are already a good twenty years.
His pavilion was covered with lichen (granular concrete tiles) when he decided to lay a copper wire running the entire length of his roof on the ridge and since then it's niquel!
By cons I do not know whether to ground this wire in case of a thunderstorm! :?:

Interesting :)
Will you have 2 photos by chance? Before after? Granular concrete = Eternit?
Did he clean during the installation?

For the grounding I do not know ....

a) If the lightning falls on the roof it is not the copper wire that will change anything.

b) Does this not risk limiting the chemical release reaction of copper ions?

No pictures unfortunately because this person is more than 500 terminals from my home!
For granular concrete tiles: I do not know if they are Eternit, I only know that the pavilion was built to 1976-77 (Phoenix houses not to name it) and that this gentleman installed his thread a few years later. excessive roofing due to the greenish lichen which strongly contrasted with the dark brown color of its tiles.
I do not think he has decapé his roof before putting this thread (comfirmer).

I would have a tendency not to put this wire to the ground, in particular so that it does not make paratonerre

Hello

I never had them grounded and I never had problems : Mrgreen: : Mrgreen: : Mrgreen:

on the other hand do not tend them too much because the effect "against low" by strong wind quickly becomes boring : Evil: : Evil: : Evil:

anti foam copper wire




by egd » 19/11/15, 10:36

Hello
I would like to install anti-foam copper wire along my ridge.
my tiles are held by copper hooks.
This tiled roof pours on a steel tank roof and goes into PVC gutters.
between the two roofs there is a kind of lead fitting (to prevent the water from rising).
is there a problem with this mount
Thank you for your answers
