How the Moss is Removed

This is what is involved in removing moss from the roof, it’s not rocket science but the work should be carried out by a company competent and experienced in working at height:

  • Cover the ground with a tarpaulin/cover
  • Erect access equipment – ladders, ridge ladders and access towers
  • Disconnect gutters from rainwater pipes and remove moss using an instrument such as a scraper
  • Use a brush to sweep the loose moss from the roof
  • Replace any broken tiles
  • Clean Out the gutters and reconnect the rainwater pipes
  • Treat the tiles with a surface biocide to stop moss/algae/lichen from suddenly growing back
  • Carry out any minor repairs – usually gaps in cement, small roof repairs etc
  • Dispose of waste
  • Re-apply the biocide every few years to keep moss growth in check

Factors that can Affect the Cost

Here is a list of factors that can increase the cost of the roof moss removal work:

  • Higher than a typical house
  • Rare tiles that are costly to replace
  • Poor access to the roof i.e. a conservatory that needs to be scaffolded over
  • Larger company adding VAT to the quote

Can This Work be Done by the Homeowner? (DIY)

No, in most cases this work will involve ladders, roof ladders and equipment such as towers and harnesses. Working at height carries significant risk and this should not be carried out by a DIYer.

How Long Until the Moss Grows Back?

The key here is to use a strong moss killer after the moss has been removed, this will treat the tiles and any gaps in between them. If you don’t treat the tiles then the moss will start to grow back as soon as it starts to rain, so expect some minor regrowth within a year.

If the tiles are treated with a biocide then all the remaining moss spores will be eliminated and it will take several years before any significant moss growth will develop.

I would suggest having the tiles retreated every 2-3 years with the surface biocide. By keeping moss growth “in check,” you will never have to scrape the roof again!

If you are concerned about using chemicals on your property, then you could consider having a copper wire or strip installed across the roof, they are not as effective but when rainwater comes into contact with this metal a small amount of copper oxide is released. This oxide is a natural fungal/moss inhibitor. The copper will not be enough to treat existing moss on a roof but should be enough to prevent growth on a roof that has already been scraped.

Reasons Why You Should Remove Moss From Your Roof:

Here are the advantages of removing roof moss:

  • Reduces gutter blockages
  • Prevents blockages in the underground drainage system/soakaway
  • Improves appearance of roof
  • Protects tiles from surface damage
  • You can actually see the tiles underneath the moss layer and replace any that are damage
  • On certain roofs where there is excessive moss growth, you can extend the life of the tiles slightly by removing the moss, although this claim should not be exaggerated

After the Moss is Removed, Can I Paint/Coat the Tiles?

No! Re-colouring the surface of the tiles has become popular in recent years but If you wish to paint or coat the tiles with a coloured paint/sealant then the tiles should be thoroughly cleaned by using a pressure/power washer. This will remove not only the moss but also lichen, dirt, oils and pollution. Failure to remove the oils/dirt/pollution will result in the coating/paint peeling off as it won’t adhere correctly to the tile surface. Simply removing the moss is not sufficient in these circumstances.

If you want to clean your roof by using a water/powered pressure washer instead of manually then please see this page.

    I have an end of terrace standard 3-bed house in Ham, Richmond, Surrey.
    Are you able to give me a quote to clean my tiles (not pressure wash) and add moss killer, plus a copper wire to help keep the future moss away.
