Roof Moss - is it worth having it removed?

Presumably if you left it long enough the house would turn into one of those subterranean earth houses with a delicious peaty topping.
The trouble is a lot of moss seems to end up on our patio, I’m thinking about the copper strip but I’m not getting up there myself.Presumably if you left it long enough the house would turn into one of those subterranean earth houses with a delicious peaty topping.

I reckon that you'd need loads of copper strip all across the roof to have much impact. I'm not convinced that it is sufficiently effective anyway.Too Late said:
We live with some big trees around the house and we are prone to some moss on the roof. Our house was built in the 1960's and has never had a roof clean. The neighbors have just had it done and it looks like a brand new roof
It got me thinking if we needed to do our roof.
Has anyone had their roof cleaned?
Is it worth doing?
Thanks

Or are we too late?

Why would someone jetwash a roof? Surely you're just asking for trouble?
We occasionally steam a roof if the client wishes. 95% we “softwash” which is in line with tile manufacturers guidelines.Generally you see our travelling friends pressure washing roofs.

I watched some jetwashing our elderly neighbour's roof last year. They were spraying upwards so the jet went under the tiles, walking all over the roof without ladders and at one point one of them saw me looking, slipped on his arse and slid right down the roof onto the garage. At that point I went round and had a chat with my neighbour and together we kicked them out, the neighbour paying them half, which is more than I would have done.We got my builder to go up and assess the damage, lots of broken tiles with two dozen or so that needed replacing, fortunately we were having an extension built and we gave them the ones off our roof.

When I was replacing a bay roof I gave it a quick sweep with a stiff brush
It looked the same within 9 months - so unless you kill the moss it's pointless
Correct. Using a professional grade biocide should see it moss free for around 5 years.When I was replacing a bay roof I gave it a quick sweep with a stiff brush

A lot of people choose roof cleaning for an aesthetic look, but its main purpose is to clear the roof from moss, which freezes and expands in the winter, cracking tiles, which can lead to water ingress.

I did mine myself, but I am fortunate to have some very good industrial ladders and roof ladders. It came off fairly easily with a stiff brush, I just let it all slide into the gutter and then cleaned the gutter out (Taking care to block the drain at the bottom of the downspout so moss would not get in there.)
That lot took about a day to shift.
The roof looks like new now, but it's not a job for anyone without a head for heights.
Our next house will be a bungalow...

Surely if it’s not blocking the guttering / valley.
A few on our street have done it to 70 year old tiles.
Patchy is an understatement
When they did our neighbours - the guys who did it asked could they use the few spare original tiles I had near the shed over them using brand new as it would look odd. Um... I’ve spares,8 as it happens for the very same reason on my roof + as I pointed out to them 2 have broken so 2 will go in there and no doubt others may break getting up to replace them. The roofer seemed a bit miffed/to the point I suspect he would have lent over and “borrowed” the tiles if I were not out in the garden.

For instance I have a fish pond with a raised wall. In theory it's isolated from the 'wild' world yet I find shimp like creatures in the filters. The pond gets filled with rain water and tap water. No bird can stand in it. Herons can stand on the wall though and reach downwards. I find worms in the roof gutters of my victorian house. It's astonishing how nature can thrive if we cut it some slack.
I have a tiny concrete yard by my pond. I let it run wild this year and it's almost a jungle. The amount of life that's there is epic and that draws in birds as well. I'll have to tidy it up as autumn progresses but shall still leave the stuff on the floor for the blackbirds to turn over.
