A question for the knowledge of PH.

We have some moss growing on the front of our roof, this is almost North facing so does not get much direct sun.

I personally don't think it is an issue other than blocking the gutters if it comes off the roof and into the gutter.

She thinks we should pay someone to go up and clean it and I presume weedkiller it all.

Have a look at the pic, I think it's nowt yes there is some moss but it's not like it is covered, but I know nothing it's just my opinion.

Copper strip works, it’s not actually doing any harm though.

Best time to clean it is in the summer when it’s dried out. What doesn’t fill up your gutters will be easy to remove.

A stiff brush to get the moss off and a copper strip on the top of the ridge , 3 hours work tops , or that's what it used to be when I used to sort this problem .
Forget about the jet wash and paint it crew .

It can also stop the water running of the tiles quickly enough and with wind can go under your laps more than usual.

Thanks for all the replies.

I think I will ignore it for now and look at getting it done next year.

Just have to convince her indoors that it's the right course of action so she will shut up about it.

I've recently been on my roof and cleaned all my moss off....(I had all the proper roof ladders and safety equipment), half a days work, best wait for a nice dry day with no wind whatsoever.

I can appreciate 95% of people wouldn't fancy tacking this though.

Genuine question, but how does a copper strip in the ridge tiles work? Is it leaching sulphate from the copper?

Edit: having reread what I wrote, what I actually intended to ask was ‘if the copper strip at the top leaches sulphates in rainwater, do these then flow down the roof, killing moss, hence no need to coat the entire roof in copper’?

Maybe I'm just a scutter, but I've never, ever felt the need to clean my roof.

My roof man said it's best left alone. Any attention just makes it worse.

It can eventually lift the tiles and allow water and wind under them, it came up on a survey I looked at recently with a house that came on the market I was interested in.

We use Wet and Forget here in NZ. Spray it on and it all dies and washes off after a month or so.

I've lived in houses with moss on the roofs for 55 years, never had a problem bigger than having to remove some moss from gutters every few years. Why do people spend money on stuff that does not need doing?

We feel this.
Actually popped in some “gutter hedgehogs” in the gutters a couple of years back....now get a fair bit of moss on the ground to pick/sweep up, but better there than clogging the down pipes! Plus I don’t have to go up the ladder so much to clear it!

Really? It feels far to light and fluffy to be lifting tiles, surely!

It's all a bit sad really and is what Attenborough has been pointing out just recently and in his current TV series. Instead of wanting to live alongside nature, most of us are just intent on killing it off one way or another.

Because it can create problems if it is left untouched.

If she is into saving the environment, isn't moss supposed to be a handy little carbon sink? (Any excuse to save a few quid!)

Can it ?

I've never had a problem, it tends to just die after a while. My roofer says to leave it alone.
