Moss on roof copper ridge supplier neede

Hi,
I have a problem with moss growing on my bungalow roof. Having read many
articles on the use of copper strip to combat the problem, I would like to
give it a go. My roof is a doddle to access and walk about on, so I'm
looking for a supplier only of copper ridge, or at least a supplier of
copper strip ( probably 30 mm wide by a few mm thick and around 100 metres
or so).The copper needs to be reasonably pure to work best.
I've searched as best I can but other than strip mill supplies I've drawn a
blank. Anybody got any addresses I could try?

thanks,

David

Still unable to get a supply other than bulk, thanks anyway.
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.

Thanks, Ian. I have read various articles on the use of copper (and zinc)
most suggest that copper will work, but has to be reasonably pure, and does
take a few years. I don't want to get a contractor in due to the cost for
something which I am perfectly capable of safely doing myself,

regards,

David

The reasons why moss grows on a roof. The roof tiles are either made of
concrete or hand made clay tiles. In the case of concrete tiles, after
about 15 to 20 years, the cement starts to detereate, releasing the sand
gravel and in conjunction with any trees close by is a perfect mixture for
vegetable growth. This is more prone on flat pitch roofs down to a 30 to 15
degrees. Hand made tiles hold water, hence moss growth. If you can walk on
the roof it can be cleaned, using a flat blade garden hoe and jet washer.
One word of warning if you use a jet wash, never point it up the roof or you
will flood the attic. Start from the top and point the jet towards the eave.
You will never stop moss from growing once its started, it will need to
repeat cleaning every year.
The only way is to have the roof tiles taken of and replaced with new.

Thanks Tony. The tiles are indeed concrete and some 30 years old, although
in very good condition. Roof pitch is shallow and I have plenty trees around
which as you mention are perfect growing conditions. I think when the
weather gets a bit better I'll follow your advice and get my pressure washer
out. Do you think that it's worthwhile using mosskiller to help slow it's
return?

to walk
From my experience of cleaning moss off a roof, you have to clean every bit
out, form in between the side over laps and in the case of double lap hand
made tiles, in between every single joint. Its a job I don't like and
usually refuse to under take. The trouble is it re accurse. Most of the
grit that moss grows in is hidden under the side channel.
As to the use of moss killer, I'm not sure if this is allowed, do to the
chemical the moss killer contains as the it all finishes in the fresh water
drain which goes straight into water courses. Best way is to scrape it off
and out with a garden hoe or small pointing trowel then jet wash off. Its a
long and tedious job. Be careful to keep an eye on how much moss goes down
the rainwater down pipe, don't block that or the main drain.

Thanks for the advice, Keith. At least access and working on my roof is easy
as it looks as if I could be up there for quite a while!

I wouldn't advise power washing concrete tiles that are 30 years old,(
brother inlaw did this then had to have the tiles coated with Aquaseal to
seal them) to kill the moss either a propriety moss killer sprayed on or a
solution of copper sulphate if you can still get the copper sulphate
crystals. Then a couple of strips of copper earthing wire wound together
along each side of the roof ridge.

As access to the roof is easy could you not just go up there with a pressure
washer and anti fungal agent and remove it that way.

Moss on Roof

STUART PENROSE21 Mar 2013 - Public
Moss on the roof a growing problem?

The question is it a problem and how serious is it.
Some roofing materials cope with moss better that others and should be removed or controlled.
Firstly, let’s deal with the power wash and treatment; under no circumstances should you let someone near your roof with a power washer!
If your roof coverings are manufactured from concrete or cement fibre the power washer will blow holes in the structure, remove the protective coating and the moss will return twice as bad as before.
There is also a very good chance of loosening fixings, dislodging flashings and cement bedding.
Most houses built in the 70s and 80s and almost in every case prior to that will have a reliance on natural air movement through the roofing materials to assist in combating condensation, if the channels become blocked with moss and algae this will reduce the air flow and can lead to damp forming. The inclusion of air vents can combat this.
North facing elevations will always have greater concentrations of moss due to the lack of sunlight, damp and dark conditions, moss thrives.
Moss spores absorb water and retain the moisture, during freezing temperatures this expands and can crack the roof tiles.

Chemical sprays
Put simply, a short term solution, to a long term problem.

How effective is Copper?
Copper when exposed to moisture produces copper sulphate, it is antimicrobial, inhibiting the growth of bacteria, moulds, algae and killing moss.
When using copper for this purpose in roof elevations there is not a “one size fits all “approach , consideration must be given to the geography of the building the proximity of trees, shrubs and sunlight exposure. Copper is not an overnight fix. Copper should be seen as an ongoing maintenance product, the longer it is exposed the more effective it becomes. It will reduce moss growth year on year, and with our air becoming more pollutant free, reduction of fossil fuels, lower emissions, healthy air more moss.
We offer free advice and can recommend the best product matched to your project.
