Moonshine Posted September 12, 2020 Share Posted September 12, 2020 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?

Bozza Posted September 12, 2020 Share Posted September 12, 2020 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.

tonyshouse Posted September 12, 2020 Share Posted September 12, 2020 Copper sulphate - but best plan is to scrape it off - don’t let it block the drain Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
Onoff Posted September 12, 2020 Share Posted September 12, 2020 Have a read of this thread. I actually bought some copper sulphate but haven't yet used it as I was worried about it harming the environment. https://forum.buildhub.org.uk/topic/10605-water-coming-in/?tab=comments#comment-179034 Link to comment Share on other sites More sharing options...
BobAJob Posted September 15, 2020 Share Posted September 15, 2020 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. Link to comment Share on other sites More sharing options...

BobAJob Posted September 15, 2020 Share Posted September 15, 2020 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.

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.

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. Edited September 16, 2020 by Ferdinand Link to comment Share on other sites More sharing options...

You should never use a pressure washer on a roof. Link to comment Share on other sites More sharing options...

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.

I did ask him why he doesnt pressure wash roofs as i think they look like brand new but he says pressure washing can cause some serious leaks and thats why he only scrapes the moss off not sure what he does after but i know he brushes on a chemical i think its biocide? it takes a while to change the colour of the tile from what ive seen and some just look ugly afterwards? 1 Link to comment Share on other sites More sharing options...
saveasteading Posted January 14, 2022 Share Posted January 14, 2022 23 minutes ago, Andrea Long said: pressure washing can cause some serious leaks Quite right. Also it is difficult to do well by spray without close access, Spraying water up from below can get under the tiles and into the house. Scraping gently gets the big lumps off....and a great substitute for compost. There is nothing wrong with a few bits of moss left on the roof, and it will be back soon enough. Plus the moss attracts insects and then birds. Link to comment Share on other sites More sharing options...
