Combatting roof moss problem

[Billydooker]

Got a few farm shed roof's with a lot of moss on them. Going to be Pressure washing out of a cherry picker the worst roof next week. Is a copper wire the best thing to put up along the top ridge to stop re-growth?

It does work ,,ever notice old council houses with slate roof's ,,used to have a copper cable strung across the ridge,,as it rain the oxide drip of and kills the moss ,,galvanised wire has a similar affect ,,nothing grows round chimney breast where tv aerials are clamped on

Spray the roof with a decent moss killer

I've just done some research on this and the stuff you want is apparently Sodium Percarbonate which is a consitituent of Vanish, stain remover. Just make up a solution and spray it on. Haven't tried it yet though.

The only place I've got moss on my roof is under the tv aerial

Put a wire both sides of the ridge, generally you don't get good coverage both sides with a single wire.

Right, I didn't read your post correctly as usual. I understand now

Do u just lay the wire on top of the ridge/top of last sheet? Or have a bracket at either end and tension it?

have used copper pipe in the past.

I bought some copper stuff off Ebay from german, 4 inch copper strip with adhesive on the back not put it up yet but i am hoping it will help moss is awful on our tiled roof.

I've pressured hot washed it in the past. Ok not brilliant idea but it does shift it. And then maybe a 2 yearly spray with hypochlorite via the pressure washer on low pressure.

Have also used washing powder, scrapers, the iron stuff (stains the roof), jeyes fluid, patio magic etc.

Copper wire = f**king waste of time.

 

[Cluny]

There is stuff called Wet and Forget anybody tried that supposed to just spray it on and watch all the dead moss blow away!

 

[Mursal]

We found the pressure washer hard work?
Jayes Fluid best applied with a hand lance on the sprayer, standing on the ground.
Not to much water maybe 50L with 2.5L of chemical.

But do a patch yourself first, see what you think in a few days/week.

Well that's saved me the hassle of doing it!

I've discovered I have a Prodec extension pole (http://prodec.uk.com/products/rollers/super-lock-extension-poles/) in the shed that I used for white washing the outside of the house and have been looking for a scraper head for it to remove the moss off the roof. Search for extension poles and some make very long ones. The best thing I can come up with is a gutter cleaning attachment (http://progutter.co.uk/product-info/4575763413). Might work, unless someone knows of anything better?

It does work. The dead moss does not blow away though. A wash or scrape may be needed to finish the job.

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.
