How to prevent the build-up of dirt and moss on roof tiles

Once you clean roof tiles, we’d recommend employing a range of preventative measures that aid in keeping the roof in good condition, safe and solid structurally sound.

Clean roof tiles regularly

First of all, it is essential to keep the roof tiles clean and remove any accumulation of dirt, algae, or lichen. Regularly cleaning the roof will avoid massive accumulations of moss and dirt and allow moisture to move freely out of the roof, ensuring that there is no risk to the roof’s structure. Moreover, the roof will be attractive to the eye.

Repair, inspect, and maintain the roof

Make sure you have your roofing examined and maintained. Also, any damaged tiles or broken areas of the roof must repair or replace as quickly as possible. Doing this can help ensure that your tiles remain in good condition since there aren’t any gaps or cracks in which dirt and moss could get trapped.

Install strips of zinc or copper

When your home is exposed to a significant amount of lichen and moss, you can put copper or zinc strips on the roof. Installing zinc or copper strips on the roof tiles will stop organisms like moss or lichen from growing. When it rains, the water flows through the roof and soaks up chemicals absorbed by the metal strips. These chemicals are poisonous to plants, and so any existing moss or lichen will be destroyed. No new vegetation can develop as the surroundings are poisonous.

Why clean roof tiles

Issues related to moisture

If roof moss, algae, or dirt are left on the roof tiles and are left untreated, it can cause many negative effects. In the first place, moss absorbs moisture quickly and does more than add weight to the roof, placing it under pressure and causing water to enter through the roofing space. Roof tiles don’t dry in the sun because dirt, moss, and lichen from barriers keep the tiles dry, causing rainwater to soak onto the roof. This could seriously harm important elements that make up your roof structure, like the rot of timber rafters that can cause permanent damage. Furthermore, moisture may cause cracks and splits in your roof tiles.

The structural bonds are damaged

Moss is a good ally for cement, meaning that it is often growing on the bond between the apex tiles, ridge tiles, and the roof. Its growth in these areas could cause serious damage by agitating and breaking bonds which are vital to the structural integrity and strength of the roof.


The presence of algae, moss, and dirt accumulations on roof tiles may cause an overheated attic and roof area since it covers the tiles, blocking heat from exiting the structure. This not only creates uncomfortable living or working circumstances, but it may also lead to expensive energy bills for air conditioning and cooling.

Blocked gutters

The presence of algae, moss, or other dirt accumulated on roof tiles may cause blockages to the drainage system for your roofline. The accumulation of moss and other debris can block the guttering system that runs along the tiled roof, which causes water to flow across into the walls of the building that can leave ugly marks but can also cause dampness inside the walls of your home.


It is important to clean roof tiles typically carry out because mold, mildew algae, fungus, or mold are beginning to appear.

Spray using the hose

Although you should never use a heavy-duty weight washer, the normal nursery hose or low-pressure washer can eliminate organisms without any issue. To avoid granule loss and water damage, keep the splashes within a few feet of shingles and then shower down.

Rub lightly with a brush

A soft bristle brush can take away dirt and most mold, but it must do gently. If you apply too much pressure, it will scratch the granules, damaging the roofing.

Mix a bleach solution

There are oxygen and chlorine bleach products that are available. You can use them to make a bleach solution. Chlorine bleach can cause damage to shingles if it is not applied correctly. Oxygen bleach is safer and less harmful.

Apply copper sulphate

Copper sulfate is a good option to spray on the roof, allowing it to sit until the mold begins to turn brown, followed by sweeping it away using the help of a bristle. After removing the mold and dust, spray the ceiling using water and ensure you wash the metal gutters. No matter how you wash your roof, you must be certain to take precautions to ensure that moisture and all that grows on it causes an unsteady surface.
