Moss on Roof tiles - ideas best way to get rid of it?

Hi

Access tower and a large high pressure washer. There are companies who will do this for you at exhorbitant rates. Dave

mr snipped-for-privacy@hotmail.com expressed precisely :

A pressure washer will shift it easily, then you will need to check your gutters are clear.

Then it will be back within a couple of years

I seem to recall that this group suggested a copper wire or tape along the ridge - as it oxydises it releases somthing that kills the moss.

Google for "roof moss copper" and got this:

OldBill has brought this to us :

So your long term solution is?

Place these strips of copper near the top of the roof. Slide the unbent edge up under a row of shingles so that the bent edge and 4 inches of copper is exposed to the weather. Each time it rains some copper molecules wash down onto the roof and create a poisoned environment that both the moss and algae dislike. Be patient as the copper eventually will turn a distinctive dark brown and then the classic green color.

would work as the moss on my roof never grows near the TV aerial.

Does the moss do any harm ? It would slow the water run off down, and its a sign of a clean environment isnt it ?

I know its a pain when ir comes loose after the winter and blocks the gutters up, but the birds like it for nesting.

I'll wait to hear what the downside is now....

Robert royall at which net

Copper is toxic to most things, if stainless worktops in kitchens were replaced

with copper they would need sterilising every day....

Why would something already toxic need to be sterilised ?

Birds sit on your aerial and s*it on the roof. It is probably this that is killing the moss on that part of the roof.

Moss likes birdshit. Aluminium salts are a herbicide though - you can find aircrash sites years afterwards by the dead circles they leave behind.

Missing letters again, n't!

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.

Best to sweep off every 5 years or so.
