Because it can create problems if it is left untouched.
This - my garage is down at the bottom of the garden and under trees - and I live halfway up a Pennine, and my word it's damp here. The roof is about and inch thick in damp, spongy moss. Every couple of years I have to climb up and scrape it all off - you can fill a couple of those big Travis Perkins builders bags with it.

Any suggestions on here as to how to stop it are just golden to me. If a copper strip really will prevent it then I'd be soooo happy.

Someone mentioned this earlier Wet & Forget, i sprayed my roof with this early summer, took a few weeks for it all to die and its not returned 6 months later.

I also did some fencing that was totally green after a few weeks its like new, been totally amazed at this product it just works.

Hardest bit is find a few dry days to apply it here in West Yorkshire.

I imagine for some under big trees with inches of the stuff, it may well.....but for the example shown, I cannot believe any issue would EVER occur due to the light moss as shown. Evidence to say otherwise please!

I have to get mine done every 6 months. Not a moss issue, just the stty gutter design the cowboys fitted.

Good stuff but use the equivalent from Wilko it is far cheaper and the same chemical. I use it on my paths every year.

My roof man said it's best left alone. Any attention just makes it worse.
This was what our roof man said too yes
You were both advised correctly.

See earlier in the thread, moss can lift the tiles allowing wind and rain under them if it is allowed to go unchecked.

& I would still say, given the picture shown, that this is NOT an issue for the OP. I bet Dog Star would dream of the “hint of north facing roof moss” the OP has!!

I'll find a pic - it's pretty bad and it gets this bad in a year.

ETA - is that mossy enough?

first I have head of that copper strip but that sounds interesting, other wise nature is a good combat to moss that down pour we had few months ago where we had 1 months rain in one day pretty much cleaned all the roof clean had plenty of fun cleaning the drains afterwards.

Also the ice and snow will harden it up this winter and wind and rain will flake it all off naturally, so get ready to clean your drains again this spring.

Try Bleach with some water and spray it is another method, just need a good sprayer and ladder and wear eye and face protection and any other safety gear before you do it.
