This article is meant to educate us on how to clean roof tiles and various relevant topics discussed in the articles.

To extend a roof’s life, it is essential to carry out annual maintenance consisting of washing, defoaming, and treating the coating. To clean the top of your home yourself, follow our articles for recommendations.

How to maintain your Roof Completely

  • Plan the application of treatments according to the weather. Ideally, the weather will be dry. Also, avoid periods of strong wind or high heat conducive to the evaporation of products. If cleaning in winter, wait for the foliage to drop altogether.
  • Preventively spray an anti-foam and algaecide liquid about once a year.
  • To limit the appearance of moss and mold, prune trees near the roof, and prune vegetation along exterior facades.
  • On a tiled roof, waterproof the surface with a water repellent product to improve waterproofing. For more effectiveness, apply the treatment in several layers.
  • Respect the dosages and action times of the products (some agents require rinsing).
  • Choose organic treatment products that respect the environment over polluting chemicals.
  • For cleaning a roof made of terracotta tiles, never use bleach because it increases the tiles’ porosity and weakens them.
  • To strip a surface with Kärcher, position the jet in the direction of the water flow, and move from top to bottom.
  • For particularly aggressive products, use a mask to protect yourself from odours that sometimes cause headaches or dizziness.
  • Equip yourself with a protective harness connected to a safety point if the roof slope is marked. Work in pairs for safety.

How to Clean Roof Tiles

A well-tended roof with clean tiles is an attractive sight and helps maintain the entire building’s value. However, cleaning the roof tiles is difficult due to the elevated location and cannot be carried out as quickly as cleaning the facade. The following eight tips should make it easier for you to clean the roof tiles so that your house becomes an eye-catcher in your neighborhood.


Do not rely on the high-pressure cleaner if you want to clear your roof of moss, leaves, and other dirt. Instead, make an effort and first remove the coarsest dirt manually, such as a ladder, broom, or scrubber. This increases the chances that later cleaning with high pressure will be more effective and that your roof will be cleaner.

How to Clean Roof Tiles

Moss cushions are among the most common problems with dirty roofs, which unfortunately cannot always be easily removed with a broom. If you have noticed a strong moss infestation, manual pulling out is still the most effective way of removing it.

To delay a new infestation with moss for as long as possible after cleaning the roof tiles, special protective coatings are available in the hardware store. When purchasing it, it is essential to pay attention to water vapour’s permeability, so not every protective varnish is equally suitable for sealing the bricks.

A high-pressure cleaner only makes roof tiles effective if you encourage the dirt to drain off in the right direction. Therefore, always work with the heater in which the moss and dirt should flow away, instead of merely holding the water jet on the brick without specifying the direction.

If you have recognized algae on your tiles in addition to moss, the simple water jet to clean the roof tiles is not sufficient. Instead, work with unique substrates waiting for you in specialist shops and address the algae problem. Whether you apply the cleaning agent manually and use it to clean the bricks or whether you can connect to a high-pressure cleaner depends on the technical device.

To apply protective roof paint, do not wait until the individual shingles are completely dry after cleaning the roof tiles. Most products from specialist retailers are designed so that the paint can still be applied to the damp bricks. The protective coating does not necessarily have to be involved with a brush; spraying on is also possible and ensures that the colour is evenly distributed.

Don’t hesitate to clean the roof tiles out even if you have planned on applying a protective coat of paint as a last resort. Modern protective products from specialist retailers can withstand rain and other precipitation forms just a few hours after being applied. Cleaning on a sunny day is possible, even if bad weather is expected in the evening.

If you are unsure when handling the ladder or challenging to reach large roof tiles, you should seek professional help cleaning the roof tiles. This may cost a bit more money than cleaning yourself, but it offers you the security of an optimal completion without the potential risk of injury.

Tips for Cleaning Tile Roofs

Tile roof cleaning is usually done because mold, mildew, algae, or fungus have started to grow.

Apply copper sulphate

Copper sulphate can be sprayed on roof mold, allowed to settle until mold turns brown, and then swept up with a broom. After removing mold, spray the ceiling with water and be sure to rinse the metal gutters.

Regardless of how you clean your roof, be sure to take safety precautions, as moisture and everything that grows on it creates a slippery surface.

Best Rain Gutter Cleaning Tools

For this type of cleaning, several essential tools are essential: 


Heights are dangerous; everyone knows it. Choosing the right type of ladder can be the difference between being safe and exposing yourself to a life-threatening fall. As a general rule of thumb, use a stepladder for one-story homes and an extension ladder for a two-story house. 

Ensure your ladder shows no signs of damage like rust, dents, or anything that could cause it to collapse while you work. Additionally, be sure to position it on solid ground and have someone hold it if necessary. Consider purchasing aluminum ladders, as they are light but sturdy.

Remember to also protect your eyes by wearing safety glasses, and wear a dust mask to protect yourself from mold spores.

This is a drill machine that you can insert into your downspout to help break up any solid mass inside so that you can rinse it out later.

Vacuum or a leaf blower with extension

This way, you can vacuum or expel the leaves and other debris that clog them, speeding up the cleaning process. These tools’ shortcomings are that they do not work for homes with more than two stories since extensions of this length are not readily available in stores. They are also not very efficient at cleaning wet debris because these tools do not generate enough force to lift heavy debris.
