Step by Step Instructions

1 Prepare to start cleaning roof tiles
2 Use anti-moss spray on roof tiles
3 Clean the roof tiles with a high pressure water spray
  • Step 1. Prepare to start cleaning roof tiles

    There are three pieces of advice worth knowing before you start cleaning roof tiles. Firstly, try and always walk where the tiles overlap as it’s the strongest part of the roof. Secondly, the surface of the roof gets slippery while you are cleaning, so install a safety rail and wear sturdy, non-slip shoes. Finally, you will save a lot of time if you have someone stay on the ground to pass things up to you.
  • Step 2. Use anti-moss spray on roof tiles

    Before you start this step, disconnect any water tanks from the gutters so no chemicals get in to your water storage. Now apply the anti-moss spray across all the tiles on your roof. When you are spraying on a roof, always start on one side and walk backwards away from where you have sprayed. That way you always walk onto a dry tile.
  • Step 3. Clean the roof tiles with a high pressure water spray

    Give the anti-moss spray time to do its job, and then use the high pressure cleaner to wash the tiles down. This will remove all the moss and lichen as well as any built up dirt. As you did in the previous step, walk backwards when you are spraying, away from the wet tiles and onto the dry ones.
