Cleaning Roof Tiles - Your Complete Guide

Cleaning Roof Tiles

Tile roofs are beautiful and can add a touch of classic charm to your home. But over time, dirt, moss, and grime can grow on them. A dirty tile roof makes the outside of your house look bad, and if you don’t clean it, it can harm you in the long run. The good news is that cleaning roof tiles can be easy. In this complete guide, we’ll show you how to get your roof back to how it looked when you first got it.

How to clean roof tiles?

Here is our step-by-step guide for cleaning roof tiles

Safety First

Before you step foot on your roof, you need to make sure you are safe. You will need a robust and tall ladder to reach your roof while staying stable and comfortable on a flat surface. If working at heights makes you feel wrong, wear shoes that won't slip, and consider getting safety gear.

Assess Damage

Your roof tiles may have damage that must be fixed before you start cleaning them. This prevents damage from getting worse and ensures you clean them right. If the tiles have holes or cracks, your roofing system may have more significant problems. For help with this step, it's best to contact a professional.

Remove Debris

Over time, the most common things that damage tile roofs are leaves, other waste, water, and other things that can break down the tile buildup. You can cut down on the number of big cleans you need on your roof by using a soft brush or leaf blower to clear debris regularly. Use a ladder and safety gear to get up on the roof. Also, be careful when you walk on the tiles. Too much pressure on the tiles will break them. It can also do a lot of damage to the roof structure.

Wet the Roof

Use a light spray from your yard hose to wet the surface of your tile roof. This will prepare the tiles for cleaning.

Use the Cleaner on the Roof

After removing all the trash, it's time to use cleaning agents. We suggest using specific roof tile cleaners to prevent your tiles from combining chemicals with other cleaners' ingredients.

Chemicals and Solvents

Several roof cleaners are available that you can use by hand or in a power washer. Bleach or sodium percarbonate is used in popular solutions. You can also mix bleach and water on your own. Some other  popular cleaners are:

Another popular choice is TSP, which comes in powder form. Many people use a 50/50 mix of bleach and water to clean their floors because it removes tough spots without scrubbing. But if that doesn’t work, you can fix it by adding some TSP powder to the fluid. You can use baking soda and vinegar to remove black marks caused by mineral buildup. Sprinkle the powder on the marked areas, pour the vinegar over it, and scrub with a rough brush.

Rinse and Dry

Keep in mind that solid chemicals can harm tile roofs if misused. After using the solution, rinse it off immediately. Do not let the solution dry on your roof. If it’s not used correctly, rust is likely to occur. Use a fine-bristled brush to scrub the tiles together. Chemicals and too much force can damage the tiles, so don’t use them. This process ensures that all the dirt, waste, and cleaning products are gone. This part of the process is dangerous because the roof will be slippery. Make sure someone is on the ground watching your every move, or spray from below if you can.

After Cleaning Roof Tiles Maintenance

Cleaning roof tiles is one of many things you can do. You will also need to perform some after-cleaning maintenance.

Hiring a professional roof cleaning service can save you time and ensure the job is done right, restoring your roof tiles to their original state. Cleaning the roof is essential for maintaining its appearance and functionality.

Pressure Washing Roof Tiles

A common way of cleaning roof tiles is with high-pressure water. You will need to rent a power washer or contact professionals. Get a 1500 PSI pressure washer and set it to medium pressure. Hold the tip 30 cm away from the tiles and wash the roof this way. As you work your way up, start at the bottom because too much water from the roof can damage the supports. Before you start, move the drainage pipes out of the way. A pressure washer can clean a roof tile well and get to all the places moss grows, but you might need to switch to high pressure for callous spots. Take care if your tiles are broken. It’s an easy way to get rid of moss, algae, and other things. You can use a mould inhibitor to keep it from returning after you clean. If you want a professional to do your task, you can rely on our Mould Cleaning Service and Pressure Washing Services.

Cleaning Terracotta Roof Tiles

You will need to start chemical cleaning of terracotta roof tiles using clean water to wash the tiles on the roof. Next, use a recyclable, water-based, high-powered cleaner. This cleaner will start killing the spores of any algae, mushrooms, lichen, or moss that is there right away. The solution will stay on your roof for up to 24 hours. This is an essential step because it will help stop the growth of new roots and keep your tiles healthy and whole. Last but not least, use filtered rainwater in a high-pressure power wash to clean your roof.

Cleaning Concrete Roof Tiles

If your roof is made of concrete tiles, hire a professional to clean it. The same is true if your house has a slate roof. Cleaning these buildings is difficult, so you could risk your life if you need to learn more and have enough experience. Pros often use a high-pressure water gun to clean concrete tile roofs. It works the best and is friendly to the environment. But you must know how to use this machine to keep it safe.

We hope you will find our cleaning roof tiles guide very helpful. One important thing you can do to keep your home in good shape is to clean the roof. Ensuring that a professional cleans your roof once a year will significantly improve the look of your home and help protect it from costly damage like roof leaks. A roof that is clean and well taken care of will last for many years.


Mixing vinegar, bleach, and soapy water can remove moss from roof tiles.

A yard sprayer, a low-powered hose, and a soft brush are the best tools to carefully and safely clean each roof tile. When washing your tiles, pay close attention to your surroundings and consider where you stand.

Using roof tile paint to restore the colour of concrete tiles can make the roof look brand new. The paint will shield the tiles from UV light’s damaging effects and keep water out.

An easy way to remove algae on your roof is to spray it with half water and half bleach. Instead of a pressure cleaner, use a hose-end sprayer. Too much water pressure can damage the shingles and make the roof last less long.

A good mix is one gallon of water, one quart of bleach, and 1/4 cup of heavy-duty cleaner like trisodium phosphate before cleaning roof tiles. When mixed with bleach, ammonia-based cleaners give off dangerous fumes, so don’t use them. Or, mix 1 cup of oxygen bleach with 1 gallon of water to make a better solution for plants.
