Moss and lichen removal

[Andy B 23]

Hello

Looking to remove moss and lichen from a bungalow roof, the bungalow is detached so access all around is not an issue, the smaller section of the roof is accessible from the garage roof.

I am looking for a method if possible that does not involve walking on the tiles, something I can apply from gutter level would be the ideal solution.

Thanks in advance.

Wet and forgot do a product you spray on

Personally I wouldn’t bother

If you treat it, it will still come back over the winter and die off during the summer.

OP,
Whatever choice you make - why not avoid any kind of chemical treatment, especially spray on's that might stay on the roof for a bit but will most certainly wash off & stay in the ground.
Chemicals that kill moss will most certainly kill tiny soil creatures, and contaminate the ground water.

Patio Magic (which I have used) and Wet & Forget (which I have not) are basically dilute forms of benzalkonium chloride. Something like 7 or 8% and you dilute it down to 1 or 2%. I bought a lot of BAC 50, which is a 50% solution of benzalkonium chloride and use that on my rather ratty front yard.

NB Any moss killer will kill the moss, that is all, it will not remove the dead moss. On a patio the dead moss needs to be removed by brushing. On a roof it may be loose enough to blow away, but then it might not.

Chemicals that kill moss will most certainly kill tiny soil creatures, and contaminate the ground water.

Total bobbins. There is a regulatory regime so that chemicals have to be tested before being sold and the conditions for use listed on the container.

Benzalkonium chloride is used in loads of products that are applied to the body, including mucous membranes where it will be absorbed into the blood stream. The key thing is to follow the instructions and use the correct dosage.

Poster #5,
OK , on the bobbins scale - you are comparing plant killing chemicals with safe medications?
Then why dont you fill a pint pot with a correct dosage, and drink it?
Would you be happy with your kids trying this experiment?

You place your trust in chemical companies such as Monsanto & Bayer - years after massive environmental and human claims bankrupted Monsanto, its still being sued for billions.
Its been Common knowledge for decades that chemicals are killing the world's Flora & Fauna - perhaps you dont do common knowledge like you dont seem to do common sense?
