Sodium percarbonate serves as the basis for oxygen bleach, which often comes in the form of a powder. In the presence of water, sodium percarbonate decomposes into sodium carbonate which is also soda ash, and hydrogen peroxide.

For this method, follow the steps below:
- First, fill a bucket with one gallon of boiling water.

- For rinsing, you have two gallons of water to fill a separate bucket, or you can use a garden hose.
- Use a ladder that has been placed in a stable position to ascend to the roof.
- Once on the roof, use a broom to sweep the roof to remove loose dirt, dust, and debris from the concrete tiles.
- In the cleaning solution, dunk a scrub brush with a long handle. Use the cleaning solution to scrub the concrete roof tiles.
- While cleaning, rinse the scrub brush frequently.
- Depending on how dirty the roof is, leave the oxygen bleach mixture on the concrete tiles for 10 to 30 minutes. The mixture needs to stay on the tiles longer, the dirtier the roof is.
- Finally, use a garden hose or the clean water in the bucket to rinse the roof.
When vinegar and baking soda combine, the acid present in vinegar breaks down baking. This leads to the release of carbon dioxide gas that can aid in removing grime off concrete roof tiles.

Sodium hydroxide is the ideal cleaning agent for mold and algae on concrete roofs since it kills the algae and clears the soil from your concrete roof tiles. It functions as a cleanser and a degreaser. In the algae and debris, it dissolves deposits made of fat, grease, oil, and protein, creating a water-soluble solution that you can wash away.
We refer to this procedure as saponification. Ensure you apply the cleaning agents with the correct dilution rates, for a set amount of time. Subsequently, then thoroughly wash with high flow rates but not high-pressure rates to eliminate the chemical and cease any lingering action.
Unfortunately, if you do not completely remove it from the surface even after it has dried it can be activated again and, once wet, continues its normal chemical reactions.
Follow these steps to clean,
- Stir the sodium hydroxide a little into a large volume of water.
- Dilute the solution to make a liter.
- Place this solution in a pressure washer,
- spray it on the roof.
- Rinse the roof with a lot of clean water afterwards.
Utilizing cold water with a high pressure is part of this cleaning technique. The force of the spray aids in liquifying and eliminating dirt, moss, and algae.
Follow these steps to carry out this cleaning process:
- Add one percent of household bleach to the water.
- Link your pressure washer to your garden hose.
- Next, set your ladder in place and use it to ascend to the roof.
- Set your pressure washer to 1,200 PSI or a medium pressure because higher pressure will damage the tiles, and point the nozzle directly over the area you wish to clean. Keep the nozzle at least one foot away from the tiles while operating.
- Start the pressure washer, then wash the debris off the roof.
- Rinse the roof with unbleached water, and then blot it dry with a clean towel.

- Once you finish cleaning the floors, discard the ammonia mixture. Rinse the bucket thoroughly to get the ammonia out.
- To remove the ammonia, use a garden hose to rinse the roof with clean water.
This method makes use of an environmentally friendly diluted cleaning solution for killing bacteria caused by mold.

- Fill your pressure washer with a solution of mold inhibitor cleaner,
- use a steady ladder to climb onto the roof.
- Turn the pressure washer on and set it at a very low-pressure
- Spray the roof and allow it to dry before rinsing with clean water.
Vinegar is a natural cleaner that is effective at removing dirt, grime, and stains from surfaces. To clean terracotta tiles with vinegar, do the following steps:
- Fill a bucket with about a gallon of water. The warmer the water, the better it will be for loosening stuck-on dirt and grime.
- Add a cup of distilled white vinegar. Aim for a ratio of roughly ½ to 1 cup (0.24 liters) of vinegar for every gallon of water.
- Stir the mixture to ensure it forms a perfect solution.
- Place the solution in a spray bottle.
- Spray the solution on the tiles and scrub with a brush to remove the dirt and grime.

Reducing vegetation or overhanging trees that may hinder roof drainage is a good idea.
To check for cracked and damaged tiles, regularly inspect your roof. If any, replace them directly.
Regularly schedule expert inspection and upkeep. Request at least twice a year’s worth of roof inspections from your contractor.
Avoid cleaning with products that contain acids, vinegar, or ammonia since these can harm or stain terracotta tile floors.
You should use copper or zinc roof trim. Because these strips produce noxious compounds that are damaging to plant life after absorbing rainwater and releasing them into the air, they stop organisms like lichen and moss from developing on roofs.
