This what we use and on the patio spray it on and let it dry and then the next rain cleans it

Eh ?
Have one here the same. Would love to know why it’s doesnt work.
Tried copper pipe instead?
No, I'll probably spray it with some of the products listed on this thread.
The wire on my roof must be getting on for 40 years old. I wonder whether it should be replaced every 5 years or so ?

the vanish soap idea leads me to this https://www.ebay.co.uk/i/2721158561...&campaignid=857250873&crdt=0&var=570924807584
I use a product like wet and forget, not the genuine stuff thats too expensive, but not on the house roof as its steep and slippery with moss

Possibly because the copper is already corroded / tarnished so won't leech enough. Also works better if the wire is in contact with the roof.
"Mate of mine is a roofer and has looked at jobs where customers have complained about a leak or two. Turns out a few weeks earlier they have had there roofs power washed by gypos to remove moss.
This is on house roofs of course."
Presuming they have "liquidated" the lead flashings??

So are these companies who power wash then apply a moss killer then a couple of costs of roof sealant up to any good, or is it a waste of time and money or likely to do more damage than good.
I have concrete roof tiles with a sand textured finish which are ideal for growing moss. Usually I gently scrape with a trowel and brush the moss down but it's sore on my knees and needs doing every couple of years on the north side.
My neighbour has had a local firm power wash and coat his tiles and it looks a clean job but not sure if they cracked any tiles or how long it will last. Also wonder if the power washer will have eroded the fines off the surface of the tiles? Tiles are 50 years old.
We are semi detached and my half looks a mess now against his side which has been painted dark red as against my original sandy, grey/yellow tiles.
To keep us looking the same I would have it done but it's not cheap and not sure if it's worth it.
Any opinions?

It can get fairly thick to the point where it needs scraping off to reduce weight on the roof. It can cause water to back up under the tiles where a big accumulation occurs. My roofing contractor recommend scraping and brushing it off but it seems to need doing every couple of years.
The roof seal contractors get a bad name but to me they look to have done a good job on the neighbours roof, but time will tell how long the coating lasts or whether more moss accumulates.

put up with whatever, in 2 years time your neighbour will be sick of repairing leaks so will be having a new roof, do the same at the same time.
would never recommend anyone walking on these tiles they crack at nothing and often puncture the felt so you end up doing a proper job + having the roof painted is nearly the same as a new roof with new felt etc.

Best stuff to kill moss on roofs or tarmac etc is good old washing powder. Just sprinkle it on the moss and you’ll be surprised how effective it is. Don’t need much powder.

I wondered if copper blasting slag would work?

what about copper sulphate paste like for foot trimming bandages? looks to me as if more would go with rain water?

One good rain storm and it would be washed away. Might as well just spray the whole roof with copper sulphate solution.
