I have mechanically cleared some moss off my clay roof tiles.

I am not going to pressure wash the tiles, but is there any week killer type product I can use to kill the rest of the remaining plant life? Application via a sprayer?

Wet & Forget is a product that gets good reviews.  I have bought some to remove moss from a north facing stone wall, But yet to use it so cannot comment further hopefully someone else can,  Costco were doing it a few weeks back.

Copper sulphate - but best plan is to scrape it off - don’t let it block the drain

I scraped as much moss off as I could and then sprayed Wet & Forget. Didn't kill or remove the existing moss but I have found there is a lot less new moss but this could just be to do with the weather.

I bought Smartseal Moss Clear.  It gets ok reviews on Amazon.  I used a Skyscraper on a pole to clear the moss then sprayed the roof with Moss Clear.

It's a metal head that is shaped to the profile of your roof tiles.  It comes with something like 10 different profile blades.  You screw it to a pole like they use for window washing brushes and run it up and down and across the roof from the ground or a ladder to remove the moss.  Removing the moss is ok. It's getting all the moss down to you so you can take it off that takes the time. It cost around £200 for head and all the profiles, which is expensive for what it is.  Definitely use a carbon pole not a aluminium one as the weight of the pole will be a problem when you have it fully extended to reach the tiles up by the ridge tiles.

 I googled it.
 

Bit much to justify for a typical householder.

True. It's being marketed as a tool property maintenance companies could use to offer roof cleaning services that don't involve them getting up on the roof.

There I was thinking you had a sleeping mistake but no....

I used a wallpaper scrapper taped to and extendable pole from a ladder 😂

 

If you want the short (24 ft) pole package it comes to £562 from there .... more from elsewhere.

 

No idea what the long - 34ft - pole costs.

 

Pole must have used Sergei Bubka as a consultant and paid him in gold medals.

wow, someone saw a market and invested, hope it pays off. a lot better than an oik with a pressure washer walking up the roof and firing it under the tiles, but still.......

You should never use a pressure washer on a roof.

Have to be a right sucker for that sort of money...

It seems to do a good job at sucking all the moss and dust out of the gutters after a moss clearing job.  It probably saves a lot of time if you were doing it professionally.
