How to Efficiently Clean Roof Tiles to Remove Moss Buildup

Updated: Jul 12, 2023

A moss buildup on the roof tiles can be an eyesore and can also cause significant damage to the roof if left untreated for a long time. Moss buildup can clog the gutters and trap moisture, which can lead to leaks in the ceiling. It can also cause the tiles to become brittle and deteriorate over time. Therefore, cleaning the roof tiles regularly is essential to remove moss buildup.

This blog post will discuss some tips to efficiently clean roof tiles to remove moss buildup.

Safety First

Climbing onto the roof can be dangerous, so it is essential to take adequate safety precautions. Wear slip-resistant shoes with good traction to avoid slipping.

Use a sturdy ladder to support your weight and safely reach the roof. If you are uncomfortable climbing onto the roof, consider hiring a professional to do the job for you.

Assess the Condition of the Roof

If the tiles are old or damaged, they may not be able to withstand the pressure of cleaning. In such cases, replacing the damaged tiles before cleaning the roof is best. If the tiles are in good condition, you can proceed with cleaning.

Gather the Required Tools and Materials

You will need some essential tools and materials to efficiently clean roof tiles. These include a pressure washer, a garden hose, a stiff-bristled brush, a bucket, a cleaning solution, and safety gear.

The cleaning solution can mix water and moss-killing solutions, such as bleach or copper sulfate. However, using the cleaning solution proportionally is important to avoid damaging the roof tiles.

Start with Manual Cleaning

Use a stiff-bristled brush to scrub the moss buildup off the roof tiles. This will help loosen the moss and make it easier to remove. It is essential to be gentle while scrubbing to avoid damaging the roof tiles.

Leave the Cleaning Solution on the Roof Tiles

Apply a cleaning solution to the roof tiles to kill any remaining moss. However, leaving the cleaning solution on the roof tiles for some time is essential to allow it to work effectively. The time required will depend on the type of cleaning solution used.

Rinse the Roof Tiles Thoroughly

Use a garden hose to rinse the roof tiles, starting from the top and working your way down. Ensure all the cleaning solution is washed off the roof tiles to avoid damaging them.

Clean the Gutters

Moss buildup can also clog the gutters, leading to water damage to the roof. Therefore, it is essential to clean the gutters regularly. After cleaning the roof tiles, remove any debris or moss buildup from the gutters.

Prevent Future Moss Buildup

Preventive measures must be taken to prevent future moss buildup on the roof tiles. Trim overhanging tree branches to prevent them from falling on the roof tiles and trapping moisture. Clean the roof tiles regularly to prevent moss buildup.

Hire a Professional

Cleaning roof tiles can be a time-consuming and labour-intensive task. If you are uncomfortable cleaning the roof tiles yourself, consider hiring a professional to do the job for you. A professional can clean the roof tiles efficiently and safely, ensuring the job is done correctly.


Cleaning roof tiles to remove moss buildup can help prevent damage to the roof and improve its overall appearance. However, following the proper cleaning techniques is essential to avoid damaging the roof tiles. If you are uncomfortable cleaning the roof tiles yourself, consider hiring a professional to do the job for you.
